Abstract

This thesis presents a method for calibrating regional scale hydrologic models using the

upper South Saskatchewan River watershed as a case study. Regional scale hydrologic

models can be very difficult to calibrate due to the spatial diversity of their land types.

To deal with this diversity, both a manual calibration method and a multi-basin

automated calibration method were applied to a WATFLOOD hydrologic model of the

watershed.

Manual calibration was used to determine the effect of each model parameter on

modeling results. A parameter set that heavily influenced modeling results was selected.

Each influential parameter was also assigned an initial value and a parameter range to be

used during automated calibration. This manual calibration approach was found to be

very effective for improving modeling results over the entire watershed.

Automated calibration was performed using a weighted multi-basin objective

function based on the average streamflow from six sub-basins. The initial parameter set

and ranges found during manual calibration were subjected to the optimization search

algorithm DDS to automatically calibrate the model. Sub-basin results not involved in

the objective function were considered for validation purposes. Automatic calibration

was deemed successful in providing watershed-wide modeling improvements.

The calibrated model was then used as a basis for determining the effect of altering

rain gauge density on model outputs for both a local (sub-basin) and global (watershed)

scale. Four de-clustered precipitation data sets were used as input to the model and

automated calibration was performed using the multi-basin objective function. It was

found that more accurate results were obtained from models with higher rain gauge

density. Adding a rain gauge did not necessarily improve modeled results over the entire

watershed, but typically improved predictions in the sub-basin in which the gauge was

located.

Introduction

1.1 Problem Description

Hydrologic simulation models have been used since 1966 to help hydrologists better

understand different hydrologic processes, describe the hydrology of a specific region,

and to predict the potential hydrologic impact that future development may cause. While

hydrologic models are often useful, accurate model predictions can be difficult to

achieve. Hydrologic modeling software typically requires large quantities of input data

that may necessitate extensive pre-processing before a model can be properly run.

Additionally, the number of unknown parameters in hydrologic models is often large, and

a significant degree of calibration may be required to ensure the model is able to

represent historical and future trends.

For regional scale hydrologic models, data management and calibration can be a

very complex task. The modeled region of interest can contain diverse land types, which

can be difficult to classify and parameterize. Regional scale models can also have

inconsistent and poorly distributed input data (i.e., precipitation, temperature, wind speed,

and humidity). The availability and relative density of weather stations strongly

influences the accuracy estimated rainfall, temperature, etc., between stations. Since these

inputs drive the model, poor data density or interpolation can lead to flawed results.

This thesis presents two contributions to the scientific literature on regional-scale

hydrologic modeling. First, a general approach used for calibration of regional scale

hydrologic models, with application to a WATFLOOD model of the Red Deer River, the

Bow River, and the Old Man River watersheds in Alberta, is presented. In this method, a

structured approach towards manual calibration is initially used to determine parameters

that have a significant influence on model output. This parameter set is then subjected to

automated calibration to optimize parameter values. The objective function used for the

automated calibration is calculated based on the model results from multiple sub-basins.

2

The second component of this study is an investigation into the impacts of de-clustered

precipitation data upon hydrologic model calibration. The goal of this portion of the

study is to determine a relationship between gauge density and a hydrologic model’s

potential to be accurately calibrated.

1.2 Objectives

There are two objectives of this study. The first is to calibrate a regional scale hydrologic

model using both manual calibration and automatic calibration methods. The steps taken

to meet this objective include:

1. Model development and assessing project limitations: The study area and the

pre-calibrated model are assessed with the purpose of determining major study

limitations. Three types of limitations are encountered. The first is caused by

missing historic data. Data sets used to fuel the model (historic precipitation), and

data sets used to evaluate the model (historic streamflows) both have missing data

for portions of the study period. The second limitation is the unknown behavior

of certain man-made hydrologic features within the study area such as dams,

irrigation canals, and reservoirs, and incorporating these features into a

continuous model is outside the scope of this project. The final limitation comes

from WATFLOOD itself. While WATFLOOD is designed to handle many

hydrologic features, not all processes can be modeled and this puts restrictions on

the ability to accurately model portions of the watershed.

2. Manual calibration: This involves trial and error variation of each of the

unknown model parameters with the purpose of determining how each parameter

influences modeling results, and to improve the modeling results. Each parameter

is also given a range based on model sensitivity that is used during automated

calibration. Both subjective visual inspection and a formal objective function are

used for model comparison in this step.

3

3. Automated calibration: The objective function used in this step is designed to

consider the results of multiple sub-basins in the model. Using the parameter set

and ranges obtained through manual calibration, a search algorithm is used to

optimize the objective function and the find calibrated values for each parameter.

The calibration is performed based on the objective function alone and the model

is validated using the results from sub-basins not used in the objective function

calculation.

The second objective of this study is to assess the relationship between rain gauge

density and calibration accuracy. Four models are set up, each with a reduced rain gauge

density. Each model is calibrated using the calibration method used in the first portion of

the study, and impacts of the de-clustered input data sets are discussed and interpreted.

1.3 Site Description

Located mostly in southern Alberta, Canada, the watershed used for this study is the

upper South Saskatchewan River, which consists of the Red Deer River, the Bow River,

and the Old Man River. With a contributing area of over 120,000 km2, these three basins

flow through diverse land types including mountains, foothills, and prairies. The study

area drains from west to east between the Rocky Mountains at the western border of

Alberta (continental divide) and the prairies of western Saskatchewan. Figure 1.1 shows

a satellite image of the study area with an overlay of the boundaries of the watersheds.

Background

This study uses a multiple basin calibration approach to calibrate a regional scale model

comprised of multiple sub-basins and multiple stream gauges. This multiple basin

calibration method has the benefit that it allows a hydrologic model to be efficiently

calibrated when testing the model against rain gauge density alterations and de-clustering.

This chapter is dedicated to providing a background on both the techniques and

tools used to complete this study. The literature review (section 2.1) provides a

background on hydrologic modeling, calibration of hydrologic models, and methods for

interpolating and de-clustering rain gauge data. This chapter also provides a brief

summary of the WATFLOOD hydrologic modeling software (section 2.2).

2.1 Literature Review

2.1.1 Hydrologic Modeling

Hydrologic modeling is an attempt to represent different aspects of the hydrologic cycle

through statistical and/or mathematical simulation. It is a powerful tool that can be used

for both research purposes and for planning and development (Seth, 2004). Software

codes capable of simulating several parts of the hydrologic cycle are sometimes used to

represent an entire hydrologic system. Although the understanding of the hydrologic

cycle continues to improve, there is still much to be learned on how hydrologic systems

function, and how they can be better modeled to meet the needs of today’s researchers

and practitioners.

Computer-based hydrologic modeling started during the 1960’s when large

computer models were used to attempt to match historical hydrologic data. The ability to

7

perform many calculations using the computer was helpful for answering complicated

hydrologic questions.

The first computational hydrologic model was created at Stanford University and

was called the Stanford Watershed Model (Crawford & Linsley, 1966). It was able to

effectively simulate precipitation, evaporation, evapotranspiration, infiltration, surface

runoff, ground water flow, and streamflow (Bedient & Huber, 2002). The goal of these

earlier programs was to continuously simulate hydrologic processes and to include all of

the interacting processes in the same model structure (Crawford & Burges, 2004).

Since the development of these early computer-based hydrologic models, there have

been several types of software of varying complexity developed to assist hydrologists in

understanding complex hydrologic processes. As a result of continued advancement,

hydrologic modeling remains a key component of the advancement of hydrologic study.

Often, the development and calibration of hydrologic models gives insight into the

limitations of modeling specific hydrologic processes and leads to improvements in

modeling software. Additionally, increased computing power has created a demand for

more field data, which in turn allows for further hydrologic study. If applied correctly,

hydrologic models are currently the best way to estimate and understand complex

hydrologic systems (Bedient & Huber, 2002). There are many types of hydrologic

models, but the three most used types are: conceptual, stochastic, and physically-based

models.

Conceptual hydrologic models use very little information about the watershed, and

provide efficient estimates of how a watershed will respond to precipitation (Fenicia et

al., 2007). Some examples of conceptual hydrologic models are linear models, Nash

instantaneous unit hydrograph, the rational method, and kinematic or dynamic wave

methods for overland flow (Bedient & Huber, 2002).

Stochastic hydrologic models use mathematics and statistics to produce an output

based on a set of input data. A typical example of this would be producing synthetic

streamflows based on a set of input precipitation data based on historical statistics from

the specific watershed (Bedient & Huber, 2002).

8

Physically-based hydrologic models attempt to simulate the hydrologic processes as

they occur in the real world and are based on our understanding of the physics of

individual hydrologic processes, e.g., infiltration, snowmelt, etc. (Seth, 2004).

Physically-based distributed models can be applied to many types of hydrologic problems

(Seth, 2004). Some common inputs for a physically based hydrologic model include

precipitation, temperature, wind speed, humidity, and initial snow depth. These are used

as input parameters to mass transfer and energy budget equations that can be used to

model snow melt, evaporation, and infiltration (Bedient & Huber, 2002).

Physically-based hydrologic models are typically set up to be single event models

or continuous models. Single event models are primarily used for the design of hydraulic

systems to handle large floods based on a single extreme precipitation event. They are

convenient in that it is easy to set up the antecedent conditions in the system, and because

they have very short run times. Continuous models are long term simulations that usually

simulate several historic precipitation events. These can range from a single season to

many years. Like single event models, continuous models can also be used in the design

of hydraulic systems, but may also include simulation goals related to base flow

depletion/recharge, evaporation, or snow melt as these hydrologic processes take much

longer than would be simulated by a single event model.

2.1.2 Calibration of Hydrologic Models

Most hydrologic models contain general equations that are intended to be useful over a

large variety of geographic areas. These equations include parameters that can be varied

to account for the hydrology of a specific study area. Without calibration, such “general-

purpose” models will not likely produce accurate, acceptable results (Debo & Reese,

2002). This is partly because the equations intended to represent natural hydrologic

processes contain parameters and coefficients that are difficult if not impossible to

estimate from field data. Once a hydrologic model has been set up to represent the

diversity of the specified, model calibration can begin.

9

Calibration of a hydrologic model is the process by which parameters that heavily

influence model output are modified in an attempt to replicate the model outputs with

historic data from the watershed (Debo & Reese, 2002). For example, it is often

desirable for the model to be able to simulate historic streamflow data given historic

precipitation data. Depending on the purpose of the model, the requirements for

calibration may vary: one model may be intended to best meet peak flows, another may

be focused on simulating low or mid flows. The goals of calibration are typically

expressed in terms of a calibration objective function defined such that the optimal

solution is that with the smallest (or largest) objective function.

There are several objective functions that can be used to assess the accuracy of a

hydrologic model. The objective function selected may depend on the specific goals of

the study. The most common objective function used for calibration of hydrologic

models is the Nash-Sutcliffe model efficiency coefficient (Nash & Sutcliffe, 1970)

defined as:

where Qo is observed discharge and Qm is modeled discharge. The coefficient is a

measure of the model’s predictive ability. The Nash-Sutcliffe model efficiency

coefficient has a range of -∞ to 1.0. The maximum value of 1.0 indicates a perfect match

between the model and the observed data. A value of 0.0 indicates that the model is as

good of a predictor as the mean of the observed flows. A value greater than 0.0 means

that the model is a more accurate predictor than the mean of the observed data, while a

value less than 0.0 results when the model is a less accurate prediction than the mean of

the observed data.

While the Nash-Sutcliffe model efficiency coefficient is one of the most common

methods for evaluating the accuracy of a hydrograph, it has been shown that very poor

models can possess relatively high Nash-Sutcliffe coefficients, and low Nash-Sutcliffe

10

coefficients can result from a good model. Because of this, it is beneficial not to

conclude on the performance of a model based on the Nash-Sutcliffe coefficient alone

(Jain & Sudheer, 2008).

Once an objective function is selected, the calibration process can be executed using

either manual calibration or automated calibration. Manual calibration is a method in

which parameters are manually varied one at a time in an attempt to improve the model

results and gain an understanding of how certain parameters influence model outputs.

Automated calibration is a method where parameters are simultaneously varied using a

search algorithm to find the parameter set that produces the most accurate model results.

Manual calibration is the most widely used method to calibrate hydrologic models

(Boyle et al., 2000). Usually used in the early stages of the calibration of a hydrologic

model (prior to automated calibration), it is a method that essentially uses trial-and-error

parameter adjustment to improve the model and determine a good parameter set (Madsen,

2000).

Often, the comparison between the observed hydrograph and the simulated

hydrograph is made purely from visual inspection. Experienced modelers can obtain

very accurate models through manual calibration, but without an objective function, it is

difficult to quantify its quality in comparison to equally plausible models (Madsen,

2000). If automated calibration is to take place following manual calibration, it can be a

good idea to monitor the selected objective function during manual calibration so that a

better understanding can be gained of how that objective function is reacting to visual

improvements in the model.

Manual calibration provides modelers with some advantages over automated

calibration. Because parameters are varied one at a time, modelers see each varied

parameter changes model outputs. This allows a modeler to determine the set of

dominant parameters that strongly influence the specific watershed. Through this

process, a modeler is also able to understand the sensitivity of each parameter and

determine reasonable starting points and ranges for the parameter set to be used during

automated calibration; this will reduce the number of iterations required during

11

automated calibration. Modelers that manually calibrate their models gain a better

understanding about how different hydrologic processes impact the output hydrographs.

Additionally, these modelers are better prepared to identify problems that may be

encountered during automated calibration (Madsen, 2000).

Though popular and useful, manual calibration has drawbacks. Each model run

requires visual hydrograph analysis (and possibly objective function calculation) and

parameter adjustment by the modeler, and makes manual calibration a labor intensive

process. The method can be complicated, and expertise from one modeler is difficult to

pass on to another modeler as the best method for improving one’s manual calibration

skill is through hands on experience and training (Boyle et al., 2000).

An increasingly popular method of improving the quality of hydrologic models is

automated calibration; however, because automated calibration approaches often require

a mathematical background and use more complicated computational tools than manual

calibration, it still remains unused by many modelers (Boyle et al., 2000). Each

parameter varied in automated calibration must be given a range defined by maximum

and minimum values. The set of specified parameter ranges is called the parameter

space. Automated calibration uses optimization algorithms to search the parameter space

to find the parameter set that will result in the best value of the objective function. The

technique is not labor intensive, nor is it biased by the modeler’s expert knowledge or

opinions (Madsen, 2003), except in the selection of the objective function and parameter

ranges.

Three things are necessary to complete an automated calibration: an objective

function, a parameter set with an initial parameter space, and an optimization algorithm.

As previously discussed, there are different objective functions to choose from. Properly

selecting an objective function that meets the needs of the specific study is critical for

developing a model that meets the needs of the modeler. It has been found that

performing a single criteria approach to automated calibration can lead to good curve

fitting, but can lead to a parameter set that is hydrologically unrealistic (Boyle et al.,

2000). A method that can help to avoid this situation is to complete in-depth manual

12

calibration prior to automated calibration to see that there are hydrologically realistic

parameter values.

The final component of an automated calibration is an optimization algorithm. For

this, there are many to choose from, which can be categorized as either local or global

search methods. Both local and global search methods are used for computationally

complex problems in which no specific algorithm can be used to solve the problem in its

entirety (MacFarlane & Tuson, 2008). While both methods may start searching from the

same point in the parameter space, local search methods will improve the result of the

objective function towards a local maximum (or local minimum) value. Global search

methods are designed to solve optimization problems that may have multiple optima

(Zabinsky, 1998).

Because rainfall runoff models can have numerous locally optimal solutions within

the parameter space (Duan et al., 1993), local search methods will often not produce a

global optimum because the results will depends on the search starting point. Because of

this, global search methods should be employed to solve hydrologic calibration problems

(Madsen, 2000). Some of the most popular methods for automated calibration are

evolution-based searches such as the shuffled complex evolution (Duan et al., 1993) and

genetic algorithms (Wang, 1991). Several studies (Duan et al., 1993; Gan & Biftu, 1996;

Cooper et al., 1997; Kuczera et al., 1997; Franchini et al., 1998; Thyer et al., 1999) have

compared genetic algorithms and shuffled complex evolution (SCE), and find that the

SCE algorithm is more effective and efficient. It has been widely used in conceptual

rainfall runoff models (Madsen, 2000).

The optimization algorithm chosen for this study is a dynamically dimensioned

search (DDS) (Tolson & Shoemaker, 2007). The DDS algorithm is novel and simple

stochastic single-solution based heuristic global search algorithm (Tolson & Shoemaker,

2007). With a purpose of finding good global solutions instead of globally optimal

solutions, the algorithm is designed to scale the search to the user-specified number of

function evaluations (Tolson & Shoemaker, 2007). Initially, the algorithm searches

globally, and as the number of specified objective function evaluations approaches, the

13

search becomes more localized (Tolson & Shoemaker, 2007). To interact with a

hydrologic model DDS requires a parameter set with pre-determined user-assigned

ranges for each parameter.

DDS has been compared to the SCE method, and has been shown to require only

15-20% of the model evaluations used by the SCE method to obtain equally good values

of the objective function (Tolson & Shoemaker, 2007).

2.1.3 Temporal and Spatial Data Interpolation Methods

The most important input to a hydrologic model is the temporal and spatial distribution of

rainfall (Lynch & Schulze, 1995; Yoo, 2002). The output of a regional scale model with

sparse rainfall data can be strongly influenced by the interpolation routine that generates

rainfall values for unmeasured areas of the watershed, and having an accurate areal

precipitation representation is crucial in hydrologic modeling (Dorninger et al., 2008).

Selecting a method to estimate rainfall distribution from rain gauges can often be a time

consuming but important problem (Lynch & Schulze, 1995).

In regional scale models with complex terrain, properly using the available data is

an important aspect of developing an accurate model (Dorninger et al., 2008). Rainfall

interpolations for regional scale models are effected by the distribution and density of

rain-gauges as this can significantly contribute to the sampling error in the estimation of

the total volume of rainfall over a given area (Yoo, 2002). Beven and Hornberger (1982)

found that, for predicting streamflow hydrographs, the correct assessment of rainfall

input volume is more important that the spatial rainfall pattern.

While a majority of this study is dedicated to the calibration of a regional scale

model, once complete, the calibration method is tested using several rain-gauge input

data sets. Input data sets are generated by interpolating precipitation input sets that

decrease in density with each subsequent trial. Though the method of interpolation is not

14

varied to generate these data sets, it is a key aspect of this study and as such must be

selected carefully.

Many techniques exist that modelers use to estimate rainfall between rain gauge

point measurements. Common techniques include: inverse distance interpolation,

Shepard’s weighted interpolation, Schafer interpolation, SACLANT interpolation, and

Kriging (Lynch & Schulze, 1995).

Inverse distance weighting (IDW) is determined according to the following

equations (Shepard, 1968):

∑=

=n

iii fwyxF

),( (2.2)

∑=

dw

(2.3)

where d is the distance between the location (x,y) where rainfall is unknown and the

given weather station (i), and F is the value of rainfall at the given weather station.

Shepard’s method employs the same weighting function, but only within a certain radius;

otherwise the weighting function is equal to zero. The radius should be selected based on

the geographic density of the data points (gauge density), and should be chosen so that

each sample radius includes at least five sample points (Yoeli, 1975).

Schafer interpolation makes use of the assumption that daily rainfall distribution

similarly resembles median monthly rainfall distribution (Lynch & Schulze, 1995). The

daily rainfall measurements from each rain gauge station are transformed into a

percentage of the median monthly rainfall at that station for that specific data (Schafer,

1991). Those values are interpolated using a two dimensional interpolation technique

onto a rectangular grid (SACLANT, 1979). The interpolated values are then multiplied

by the gridded median monthly rainfall values to result in daily rainfall estimates (Dent,

Lynch and Schulze, 1988).

15

SACLANT interpolation is another two dimensional interpolation used for a

rectangular-gridded shaped study area, such as that used in the WATFLOOD software.

Values are initially assigned to each unknown point in the rectangular grid and then an

iterative process is performed where the unknown values are altered (improved) until the

surface of the precipitation values has obtained a targeted value of smoothness through

the known data points (SACLANT, 1979).

The Kriging method of interpolation uses a semi-variogram model to interpolate a

set of points (ArcInfo, 1991). The semi-variogram is a function that represents the

expected difference in value between sample points based on a given radius and

orientation (Clark, 1979). This model can be altered to be spherical, circular,

exponential, Gaussian, linear, universal linear or universal quadratic. A study

investigating the influence of different semi-variogram models (Lynch & Schulze, 1995)

found the universal linear model to produce the lowest root mean square errors when

attempting to interpolate known rainfall data. Statistical methods like Kriging can be

optimal in a statistical sense but are not applicable to some studies (Ahrens, 2005).

It has been found that for a regional scale models with a strong climactic gradient

and a sparse data set that IDW and Kriging are the most efficient towards generating a

model that can produce accurate hydrographs when calibrated (Ruelland et al., 2008).

The IDW method was found to be a significantly less time consuming process relative to

Schafer, SACLANT, and Kriging (Lynch & Schulze, 1995), and is the method selected

for this study.

2.1.4 De-Clustering

While it has been found that varied rain-gauge density can have very little effect on

modeling results in regions with relatively high rain-gauge densities (Allen &

DeGaetano, 2005), this study focuses on a region with a sparse, poorly distributed data

set. For this study, rain-gauge density will be decreased using the de-clustering method

16

described in this section, and the impacts on hydrologic model calibration will be

assessed.

De-clustering is a term used to describe a method in which data points are removed

to reduce the known, unknown, or estimated negative effects of clustered data to obtain a

data set that is more representative of underlying data (Smith, Goodchild, Longley,

2006). While several methods for de-clustering data exist, the technique has not been

extensively studied in the context of hydrologic modeling. Ahrens (Ahrens, 2005) found

a slight improvement using de-clustering for one of four rain gauge densities evaluated.

The method used by Ahrens (Ahrens, 2005) selected the closest pair of rain gauges and

eliminated the gauge which had the next closest rain gauge to it. For this study, de-

clustering will be performed using a search that will calculate a “clustering index” for

each rain gauge as follows:

∑=

=N

iidCI

1

2 (2.4)

where di is the distance between the selected rain gauge and the closest neighboring rain

gauge and N is the number of neighboring rain gauges used to calculate CI. For each rain

gauge, di is calculated for the closest four neighboring rain gauges and the gauge with

lowest CI is removed and the process is repeated. An example study area is shown below

in figure 2.1. In this example, the x-y locations of the rain gauges, labeled Xi, are shown

in table 2.1.

Table 2.2 shows the CI calculated using the lowest four distance squared values for

each rain gauge. The gauge selected through this method was gauge X5 with a CI of 28.

That gauge would be removed from the interpolation, and if further de-clustering was

desired, the process would be repeated, but starting with the updated gauge distribution.

2.2 Watflood

The hydrologic model used for the study is WATFLOOD. It is a physically-based

routing model combined with a conceptual hydrologic simulation model (Kouwen, 2007).

In WATFLOOD, a watershed is divided into a Cartesian grid, and each grid square is

subdivided into one or more land use types based on satellite imagery. The behavior of

each assigned land class is then governed by the equations of conceptual hydrologic

models and the land class parameters of WATFLOOD (section 2.2.2). An example of

how a specific grid square is handled is shown in figure 2.2.

Figure 2.2 – Group response unit and runoff routing concept (Donald, 1992; Kouwen,

2007)

In figure 2.2, the grid square is allocated in to land types (A, B, C, D) based on the

satellite image, and each land type is handled in the model as a separate watershed. The

runoff from each of the individual land class models is added to the physically based

streamflow routing model (Kouwen, 2007).

19

WATFLOOD simulates only a subset of the physical processes occurring in nature,

but includes: infiltration, evaporation, snow accumulation, interflow, base flow, and

overland channel routing (Kouwen, 2007).

2.2.1 Model Requirements

The WATFLOOD model used for this calibration is essentially fuelled by just two

hydroclimatic inputs: temperature and rainfall. Each of these inputs is taken from historic

data sets, and unknown data points (grid cells) are interpolated. Additionally, each grid

cell requires information to describe the specific land it represents including (Kouwen,

2007):

N – Grid cell number

NEXTI – Receiving cell number. This tells WATFLOOD which grid cell the streamflow will be sent to.

XX, YY – Grid cell location from bottom left corner of grid.

DA– Drainage area in km2.

IBN – River class

1,2,…N – Fractions in each land cover type.

The model requires parameter assignment for both the land type and river class

parameters (described in section 2.2.2) as well as values for the initial conditions of both

snow depth and streamflow, all of which can be modified in the WATFLOOD input files.

2.2.2 Model Parameters

While directly measured meteorological data is used to fuel the model, model behavior

heavily relies on the values of many adjustable system parameters. The primary

parameters driving the model results may be divided into land class parameters, which

20

are dictated by land use and soil type, and river class parameters, which are dictated by

drainage area, geographic location, and sub-basin boundaries. The default values listed

with each parameter shown are not considered WATFLOOD specific defaults, but are

simply the defaults arrived at in this study.

There are five river class parameters. The first two are related to how

WATFLOOD handles base flow:

LZF – Lower zone function (default = 0.200 x 10-5)

PWR – Exponent on lower zone function (default = 0.200 x 101)

Both LZF and PWR effect base flow the depletion function (QLZ) according to the

following equation:

PWRLZSLZFQLZ *= (2.5)

where LZS is the lower zone storage in each grid cell and QLZ is the lower zone flow

(base flow). All land classes present in each grid (except impervious) contribute to the

lower zone storage.

There are two river roughness parameters:

R1 – Flood plain roughness coefficient (default = 0.200 x 101)

R2 – River channel roughness coefficient (default = 0.100 x 101)

Both R1 and R2 are transformed to values of Manning’s n and then subject to

Manning’s equation to determine the average channel velocity:

21

32

SRnk

V h= (2.6)

where k is a conversional constant, n is the Gaucklet-Manning coefficient, Rh is the

hydraulic radius, and S is the slope of the water surface.

21

MNDR – Meander factor (default = 0.100 x 101)

The meander factor is a ratio of how long each channel in the grid is relative to the

length of the grid.

The parameters related to land use are as follows:

• DS – Depression storage (mm) (default = 0.200 x 102)

• DSFS – Depression storage for snow (mm) (default = 0.200 x 102)

• RE – Interflow depletion coefficient (default = 0.302 x 10)

• AK – Soil permeability for bare ground (default = 0.904 x 101)

• AKFS – Soil permeability under snow (default = 0.140 x 102)

• RETN – Upper zone specific retention (default = 0.750 x 102)

• AK2 – Upper zone resistance factor for bare ground (default = 0.125 x 10)

• AK2FS – Upper zone resistance factor under snow (default = 0.984 x 10)

• R3 – Overland roughness for bare ground (default = 0.101 x 102)

• R3FS – Overland roughness under snow (default = 0.394 x 102)

• R4 – Impervious area roughness (default = 0.100 x 102)

• CH – Channel efficiency factor (default = 0.900 x 10)

• MF – Melt factor (mm/°C/hr) (default = 0.139 x 10)

• BASE – Base melt temperature (°C) (default = -0.115 x 101)

• RHO – Snow density (relative to rho H20) (default = 0.333 x 10)

• FTAL – Forest vegetation coefficient (default = 0.850 x 10)

Not all parameters described above will have a significant effect on modeling

results. Depending on the specific model, certain parameters can strongly influence

different portions of the model. The entire parameter set will be analyzed for

significance during manual calibration; however, not all parameters will be adjusted

during automated calibration.

Chapter 3

Model Development & Calibration

Properly calibrating a hydrologic model is an essential step towards using that model as a

basis for experimentation and understanding. While many methods of calibration can be

used to improve the accuracy a model’s outputs, no method can guarantee the most

accurate model possible; in fact, it is likely that no ‘best’ solution exists and that several

equally accurate models can be produced with very different parameter sets (Beven,

2000).

Parameters that affect the behavior of the entire model are sometimes determined

through the calibration of only one sub-basin. For local scale models, this can be very

effective since many parameters are not likely to vary significantly through the basin.

However, due to variation of land types of a regional scale model, calibrating parameters

one sub-basin at a time is less likely to produce a parameter set that represents the

behavior of the entire watershed; therefore, multi-basin calibration approaches are

needed. The calibration method described this chapter is performed on a regional scale

model. It promotes parameter determination through an objective function that is

calculated from the results in multiple sub-basins.

The following sections review the development of the hydrologic model for the

Upper South Saskatchewan River case study, as well as model calibration as it applies to

WATFLOOD hydrologic models. Section 3.1 outlines the model development and data

analysis that was performed prior to calibration. This includes the model discretization,

gauge locations, available data sets, and study limitations. Section 3.2 provides a

description of the manual calibration process. This section includes a description of the

objective functions used, sub-basin selection methods, a description of the parameters

used for calibration and how they affect model outputs, an example manual calibration

for a single sub-basin, and a summary of the calibration results. Section 3.3 outlines the

steps taken during automated calibration. These include a brief overview of the

23

optimization algorithm, a summary of the parameters selected and their optimization

ranges, a description of the objective function weighting method, an overview of the sub-

basins used for the automated process, and a summary of the automated calibration

results.

3.1 Upper South Saskatchewan River Model Development

Before model calibration can begin, the study area and the available historic data must be

understood. This section provides an overview how the study area has been represented

using a WATFLOOD hydrologic model, a summary of the data sets available for the

study, and a review of some limitations that were encountered during model

development.

3.1.1 Study Area & Model Discretization

The watershed used for this study is the Upper South Saskatchewan River. Located in

southern Alberta, Canada, this watershed is made up of three major rivers: the Red Deer

River, the Bow River, and the Old Man River. The watershed has a contributing area of

over 120,000 km2 and flows east from the continental divide. For the purpose of

developing a regional scale hydrologic model of the watershed, the study area has been

divided up into 1341 grid cells, each with an area of approximately 100 km2 (10 km x 10

km). Figure 3.1 shows a map of the study area, while Figure 3.2 shows the gridded form

of the study area.

24

25

Each grid cell must have a designated river class, and must be assigned one or more

land uses. Using a combination of satellite imagery, sub-basin boundaries, and

contributing area, three river classes were designated. The three river classes are:

Class 1 – Mountain/Foothills stream (contributing area < 1000 km2 and visually

identifiable as a region with high vegetation from satellite imagery)

Class 2 – Prairie stream (contributing area < 1000 km2 and visually identifiable

as a region with low vegetation from satellite imagery)

Class 3 – Major River (contributing area > 1000 km2)

Figure 3.3 shows the assigned river classes for each grid cell.

For this study, land use was divided into nine land classes: dense forests, light

forests, mixed forests, open, wetlands, agriculture, glacier, water, and impervious. Each

land class was assigned using remotely sensed land cover data (Kouwen, 2007). Figure

3.4 shows the distribution of each land class in the watershed.

As shown, a majority of the land use (86%) in the watershed is characterized as

The model is set up to output streamflows at 30 grid cell outflow points in the

model which roughly corresponds to the 30 sub-basin stream gauges that exist in the

watershed and are shown on figure 3.5. The modeled (and measured) drainage areas and

3.1.2 Gauge Locations & Available Data Sets

For this study, the hydrologic model has been set up to simulate continuously from

January 1, 2002 to December 31, 2005. This study utilized historic data from 30 stream

gauges (Environment Canada, 2007a) and 28 weather stations (Environment Canada,

2007b). Stream gauge data are in the form of average daily flow from each stream. Each

stream gauge provides data for the corresponding sub-basin and is located at the outlet of

a grid cell.

The available historic streamflow data from each stream gauge determine which

sub-basins should be used for calibration. The available stream gauge data are shown in

table 3.2.

3.2 Manual Calibration

This section provides an outline of how manual calibration was performed on a

WATFLOOD model of the Upper South Saskatchewan River watershed. The purpose of

manual calibration is to determine a finite set of parameters that strongly influences

modeling outputs. These parameters will be manually adjusted to values that result in

significant improvements in model outputs. Selecting the influential parameter set and

31

determining an initial value for each parameter through manual adjustment reduces the

parameter set and parameter space to be used for automated calibration and may produce

more accurate results. Described here are the objective functions used during manual

calibration, the method used for selecting sub-basins to calibrate, a description of the

most relevant and sensitive parameters that control model outputs, sensitivity of

calibrated parameters, and results obtained from manual calibration.

3.2.1 Objective Function

The objective function used for manual calibration (and later automated calibration) is the

Nash-Sutcliffe model efficiency coefficient (Nash & Sutcliffe, 1970). The general form

of this equation is:

where Qot is the observed discharge and Qm

t is the modeled discharge for the time period

t. Either daily flows or monthly average flows were used as a basis for model

comparison. For the daily coefficient, the daily peak flows were used for Qo and Qm, and

for the monthly coefficient, the average of the daily peak flows for each month were used

for Qo and Qm.

In addition to the daily and monthly Nash-Sutcliffe model efficiency coefficients,

visual hydrograph inspections were performed to determine the effect of each parameter

on model outputs. Since the study does not aim to compare calibration results found

using different objective functions, no other measures will be used.

32

3.2.2 Sub-basins Selected for Calibration

Each time a parameter was varied, the objective function was calculated for certain sub-

basins and visual inspection of the hydrographs was performed. Prior to any parameter

variation, the most appropriate sub-basins were selected for the purpose of learning the

most from each parameter variation.

Throughout the calibration process, results from certain sub-basins are used to

calibrate the model, while others are used for model validation. Validating the model is a

process in which results from some sub-basins that were not used to measure model

performance are compared to confirm model improvements. Limitations encountered in

this study restricted the number of sub-basins that could be trusted for calibration or

validation. Before sub-basin selection could take place, it was important to recognize and

address the limitations this case study. Here, these limitations can be classified into three

categories: data limitations, limitations caused by man-made hydraulic features,

hydrologic modeling limitations.

Data Limitations

While the streamflow data set contains historic measurements from 30 stream

gauges, it is clear from table 3.2 that the data set is not complete. Of the 30 stream gauge

locations, only 13 contain daily data for the entire study period. One gauge has no data

available for the study period, and several others are missing entire years of

measurements. The remaining gauges have only summer data, which can still be useful

for model validation purposes. The limited data set must be considered when selecting

basins for calibration (section 3.2.2).

Man-made Hydraulic Features

One portion of the study area is heavily affected by man-made reservoirs and

irrigation canals. Sub-basin three (see figure 3.5) is the watershed of the Little Bow

River and has a drainage area of approximately 6,800 km2. Of that area, drainage from

the upper 4,230 km2 is diverted into Travers Reservoir, and only 30 % of the annual

33

drainage is released back into the Little Bow River (Atlas of Alberta Lakes, 2005). The

other 70% of the drainage is diverted into Little Bow River Lake which feeds irrigation

canals for the region. Since the drainage released to the Little Bow River is controlled

and depleted rather than naturally drained, the model output from this sub-basin, which

only considers environmental influences, can not be used for calibration. Since this sub-

basin makes up over 20% of the drainage area for Oldman River watershed (sub-basin 2),

modeling results from the Oldman River are not useful for calibration.

Hydrologic Modeling Limitations

Hydrologic modeling limitations are the modeling software’s inability to represent

certain hydrologic processes. Here, the major hydrologic modeling limitation is the

simplification of processes simulated on prairie agricultural land use. Fifty-nine percent

of the entire watershed is allocated as agricultural use, most of which is located in the

prairie region of the study area. Two aspects of prairie hydrology make hydrologic

modeling on a regional scale extremely difficult. First, blowing snow can transport up to

75% of annual snow fall from open fields (Fang et al., 2007). This leads to varied snow

melt patterns due to drifts, and lengthens spring runoff. This phenomenon is not

simulated with WATFLOOD. Second, because much of the prairies contain glacially

formed depressions many basins are internally drained. The runoff from internally

drained basins contributes to pools that are formed in these glacial depressions. From

there, water either infiltrates or evaporates. Only during the most extreme runoff events

will these pools spill over and contribute to streamflow (Fang et al., 2007). The model

could not be setup to simulate these hydrologic processes because of limitations with the

WATFLOOD software. Because these two aspects of prairie hydrology are not

simulated with WATFLOOD, calibration of sub-basins dominated by the agricultural

land use is limited in this study. The agricultural land class parameters are not used

during the initial manual calibration process; however, they are altered to improve

modeling results once the other land class parameters have been estimated through

manual calibration.

34

A second hydrologic modeling limitation in this study is the presence of glaciers in

the mountains that lie along the western portion of the study area. Though they make up

a very small percentage of any sub-basin (15% maximum), streamflow in watersheds that

contain glaciers tends to be dominated by their summer melt cycles. WATFLOOD holds

a limitation on initial snow depth at 8850 mm (8.85 m). This is not a high enough value

for a glacier, as the snow cover should be effectively infinite for the purposes of

modeling. If the glacier land class was assigned an initial snow depth of 8.85 m, the

snow would melt off during the first spring, and the glaciers would no longer contribute

to streamflow in the model as they would in reality. For this reason, several basins that

contain significant glaciers (>5%) are not used in model calibration or validation.

The goal of initial sub-basin selection was to remove sub-basins with flawed or

incomplete data sets. For the selection of sub-basins used during manual calibration, sub-

basins with complete sets of streamflow data are desired. Additionally, sub-basins that

are dominated by a certain land class are determined. When a sub-basin is dominated by

a specific land class, the modeling results are heavily reliant on those land class

parameters. For example, sub-basin 25 is the best candidate for calibrating the dense

forest land class parameters (63% coverage – table 3.1). Starting with the default values,

dense forest land class parameters could be calibrated using sub-basin 25, and then the

parameter values would be applied basin-wide.

The land class parameters chosen for manual calibration were dense forest, light

forest, mixed forest, and open land. These were selected because they represent the

largest portion of the study area that is not dominated by different prairie drainage

phenomenon. Agricultural land class parameters are calibrated as well, but because of

unpredictable prairie hydrology, they were manually adjusted last and while considering

the results from several sub-basins at a time. Considering the agricultural land class

parameters last prevents the unpredictable behavior of prairie hydrology from producing

parameter values that have poor accuracy throughout the entire watershed. Instead,

knowing that the hydrology is unpredictable, the agricultural parameter values are

adjusted last. These adjustments will be for the purpose of improving the objective

function and not necessarily to represent the hydrology of a specific sub-basin’s

35

agricultural land use (which is known to be unpredictable and geographically diverse).

The sub-basins selected for manual calibration are shown in table 3.3.

Figure 3.7: Sub-basins selected for manual calibration

36

As shown above, the sub-basins are diverse in drainage area, but not in geographic

location as the southern portion is not well represented in manual calibration. The

presence of Travers Reservoir in the southern portion of the study area controls and

diverts too much water for model results to be considered relevant.

It is important to note that, while only the sub-basins shown above have been

selected for manual calibration, results from other sub-basins are also compared to gauge

data for validation purposes.

3.2.3 Calibrated Parameters

First, a sensitivity analysis was performed on all model parameters, and then only

sensitive parameters were subjected to manual calibration. To determine which

parameters should be calibrated, it is important to understand the function each parameter

serves within the model. This section summarizes the parameters that were found

through trial and error to have a significant effect on model outputs when altered.

River Class Parameters

Starting with the pre-calibrated model (all parameter values set to defaults as

described in section 2.2.2) each parameter was varied one at a time (+ 25%) and the

model was run. After each model run, the daily Nash-Sutcliffe coefficient was calculated

and the hydrograph of a specific basin was visually analyzed. Visual analysis combined

with parameter descriptions (Kouwen, 2007) helped determine how each parameter

altered the modeling of each hydrologic process in WATFLOOD. Often, the visual

analysis was challenging since changes in the hydrographs were small and difficult to

decipher, which is why the objective function value was also as a primary tool during

manual calibration. The sub-basin used for this initial sensitivity was sub-basin nine, and

had an initial daily Nash-Sutcliffe coefficient of -0.096. Table 3.4 contains a list of river

class parameters, the parameter variation for the sensitivity trial, the objective function

changes that resulted from parameter variation, and how it influences the hydrologic

37

model. Each parameter was varied from their respective default values (described in

section 2.2.2).

Table 3.4: River class parameter initial sensitivity and hydrograph impacts for sub-basin

nine

R1 + 25% 0.011 magnitude and timing of peak flowR2 + 25% 0.044 magnitude and timing of peak flow

MNDR + 25% 0.023 magnitude and timing of peak flow

The river class parameters all produced measurable differences in the daily Nash-

Sutcliffe coefficients. Only one parameter was removed from the manual calibration as a

result of the river class sensitivity analysis, and it was R1. Even though adjustments of

R1 produced measurable hydrograph changes, this process showed that both R2 and

MNDR influence the model in the same fashion as R1 and thus it was eliminated as a

calibration parameter.

Land Class Parameters

Land class parameters are analyzed in the same manner as river class parameters,

but are considered separately for the purpose of selecting a parameter set that represents

all of the significant hydrologic and hydraulic functions that influence the model. The

land class parameters that were considered during the initial portion of manual calibration

are described in section 2.2.2. Table 3.5 contains a list of land class parameters, the

parameter variation for the sensitivity trial, the objective function changes that resulted

from parameter variation, and how it influences the hydrologic model.

There are several parameters that have little to no effect on the modeling results

(DS, DSFS, AK, AKFS, R3, R3FS, R4, CH, and RHO) and were removed from the

manual calibration process. Of the seven remaining land class parameters that had a

higher impact on modeling results (RE, RETN, AK2, AK2FS, MF, BASE, and FTAL), the

RE, AK2, and AK2FS parameters were observed to have the same effect on the output

hydrographs. Since RE had a more significant effect on the daily Nash-Sutcliffe

coefficient, it was retained for the manual calibration and AK2 and AK2FS were removed

from the list of parameters to be further calibrated.

The parameters that were considered for further calibration were: LZF, PWR, R2,

MNDR, MF, BASE, RE, RETN, FTAL.

3.2.4 Manual Calibration Steps

This section outlines the method used during manual calibration. Using sub-basin nine as

an example, the parameters selected for manual calibration in section 3.2.3 are varied in a

specific order to improve the accuracy of the modeling results.

39

Starting with the pre-calibrated model the hydrograph and daily Nash-Sutcliffe

coefficient were analyzed for a specific basin. One of the sub-basins used during manual

calibration was sub-basin nine. A comparison of measured vs. modeled results with

default parameter values for sub-basin nine is shown in figure 3.8.

Figure 3.8: Measured streamflows vs. modeled streamflows from pre-calibrated model of

Red Deer River below Burnt Timber Creek (sub-basin 9)

The modeled hydrograph consistently predicted flows that were less than the

measured values. This was a result of both the magnitude of peak flows, and the shape of

the base flow depletion curves. The Nash-Sutcliffe daily coefficient for the pre-

calibrated sub-basin was -0.096. A general algorithm used to improve the hydrograph

manually for each sub-basin is described as follows:

1. Set initial parameters (default values) for all calibrated parameters

2. Run model and identify visually analyze for strengths and weaknesses in

the output hydrographs (magnitude of peak flows, etc)

40

3. Adjust base flow parameters (LZF, PWR) to improve the base flow

depletion curve using both visual hydrograph analysis and the results of

the objective function

4. Adjust streamflow parameters (R2, MNDR) to improve timing of peak

flows using both visual hydrograph analysis and the results of the

objective function

5. Focusing on the initial melt portions of the model outputs, adjust the snow

melt parameters (MF, BASE) to improve the timing and magnitude of the

peak flows resulting from snow melt using both visual hydrograph

analysis and the results of the objective function

6. Adjust remaining parameters (RE, RETN, FTAL) to improve magnitude of

all peak flows (those influenced by snow melt included) using primarily

the results of the objective function

Steps 2 – 6 were performed iteratively using small parameter adjustments to ensure

that certain land class parameters were not adjusted to hydrologically unrealistic values to

compensate for inadequacies in the default parameter values of other land classes.

The purpose of visual hydrograph inspection was that particularly in the early

stages of manual calibration, adjusting parameters that vary the timing of peak flows and

base flow depletion (LZF, PWR, R2, MNDR, MF, and BASE) sometimes lead to an

improved objective function, but a model that is further away from a reasonable

representation of historic hydrographs when visually inspected. The objective function is

not a perfect measure of model performance, and visual inspections help to ensure that

modeling improvements occur when the objective function improves as sometimes the

opposite can be the case. Since RE, RETN, and FTAL did not alter the timing of the

hydrographs they were manually adjusted using objective function results only (though

intermittent visual observations were still made to for validation). Adjusting only the

parameters selected in section 3.2.3 the manually calibrated hydrograph for sub-basin 9

41

produced a daily Nash-Sutcliffe coefficient of 0.738. The hydrograph is shown in figure

While the monthly Nash-Sutcliffe coefficient was not considered during calibration,

it was used as a form of validation for the calibrated model. The monthly Nash-Sutcliffe

coefficient improved from -0.026 to 0.893.

The process of manual calibration was performed on each of the sub-basins shown

in table 3.3, each time focusing on the land and river class parameters that dominate those

basins respectively (shaded values). To complete the process of manually calibrating

four river class parameters for three river types, and five land class parameters for five

land types required approximately 2500 model runs.

3.2.5 Calibration Results

Manual calibration was performed on land class and river class parameters that had

significant effects on the sub-basins listed in table 3.3. Outputs from several sub-basins

with incomplete data sets were considered for the purpose of model validation.

Additionally, while the performance metric of the Nash-Sutcliffe monthly coefficient was

not used directly as a measure of accuracy, it was compared for the pre-calibrated and

manually calibrated models to provide another measure of model accuracy. The

parameter values found through manual calibration for each river class and land class

parameter described in section 3.2.3 are shown in table 3.6 and 3.7 respectively.

To determine the success of manual calibration, results from sub-basins that were

not used to manually calibrate the model (sub-basins not in table 3.3) were considered.

Though these sub-basins did not have complete data sets, their Nash-Sutcliffe coefficients

were calculated by comparing only the data available with modeling results. The pre-

calibrated and manually calibrated values for the Nash-Sutcliffe daily and monthly

coefficients are shown in table 3.8. Shaded rows indicate sub-basins used to manually

Though not all sub-basins were used during the manual calibration process, model

accuracy was improved for almost all cases. Since the calibrated parameters influence

modeling results watershed-wide, adjusting a parameter value to improve the results of

one sub-basin can change (hopefully improve but possibly degrade) modeling results in

other sub-basins. The model’s accuracy was improved for 15 of 19 sub-basins (7 of 9

validation sub-basins) for the daily Nash-Sutcliffe coefficient, and for 19 of 19 sub-basins

(9 of 9 validation basins) for the monthly Nash-Sutcliffe coefficient through automated

calibration. The average of both the Nash-Sutcliffe daily and monthly values also

increased significantly through manual calibration. Although the average values of the

objective function may not be the best way to evaluate the success of all hydrologic

calibrations it is effective in this case since each sub-basin (with the exception of sub-

basin 1) is a head water basin and is considered independently of all others. Another

option for comparing watershed-wide success would be a weighted average of the Nash-

Sutcliffe coefficients using sub-basin area, rainfall, streamflow, or another measure as the

weighting function. The objective function is weighted by average streamflow during the

automated calibration in the following section.

44

3.3 Automated Calibration

The purpose of using an automated algorithm to calibrate the model was to refine some

of the estimated parameter values found from manual calibration to improve model

results. While manual calibration was used to identify important parameters, automated

calibration searches the parameter space of some of those parameters to find the best

solution within the given parameter ranges. This section provides an outline of how the

manually calibrated model was improved using automated calibration. The method uses

an objective function that is calculated using the results from multiple sub-basins in each

trial. Described in this section is a brief description of the optimization algorithm

selected for this study, an outline of the parameter ranges used, the objective function

used, the selection of sub-basins, and results.

3.3.1 Optimization Algorithm (DDS)

The optimization algorithm chosen for this study is the dynamically dimensioned search

(DDS) (Tolson & Shoemaker, 2007). For DDS to function with WATFLOOD, it

requires a model parameter set, and the corresponding parameter ranges in terms of

maximum and minimum values. The DDS manual (Tolson & Seglenieks, 2007)

recommends that for optimization problems involving 10 or more parameters that 1000

function evaluations can typically generate reasonable results, so that will be the value

used for this study. Details on the specifics of the DDS algorithm can be found in

(Tolson & Shoemaker, 2007).

3.3.2 Parameter Selection & Parameter Ranges

The parameters selected for automated calibration are chosen with a goal of representing

the major hydrologic processes that heavily influence modeling results. Through the

manual calibration the dominant processes were found to be: snow melt, base flow

45

depletion, evapotranspiration, streamflow rates, evaporation, and interflow. The

parameters selected to represent each process are shown in table 3.9:

Table 3.9: Automated calibration parameters selected by hydrologic process

Hydrologic Process ParametersSnow Melt MF, BASEBaseflow Depletion LZFEvapotranspiration RETNStream Flow Rates R2Evaporation FTALInterflow RE

Each process was assigned one parameter for automated calibration except for snow

melt. For snow melt, two parameters were selected since both MF and BASE have

significantly different effects on the output hydrographs. Both PWR and MNDR were not

included in the automated calibration process because they influence the output

hydrographs in a very similar manner to LZF and R2 respectively, but less significantly

(table 3.4).

Initially, the range of each parameter was chosen as approximately +/- 50% of the

value obtained from manual calibration as long as that range does not exceed the

reasonable boundaries for the parameter which are governed by hydrologic and physical

limitations (i.e. MNDR cannot be less than 1). For BASE an initial range was selected as

+/- 1.5 degrees, and for FTAL, initial ranges were selected as +/- 0.2 (minimum of 0.01,

and maximum of 1.0).

Following each automatic calibration trial, the ranges for each parameter were reset

according to the results of the trial. Figure 3.10 depicts a decision diagram outlining how

parameters were adjusted after each trial.

3.3.3 Objective Function Weighting Method

The objective function used for automated trials is a weighted sum of the Nash-Sutcliffe

average measured flow for the calibration period from each sub-basin involved in the

calculation.

47

3.3.4 Sub-basin Selection

The sub-basins selected for automatic calibration were not the same set selected for

manual calibration. The purpose of this was to increase the number of sub-basins that

could be used as validation sub-basins to gain more information about the success of the

weighted objective function. The sub-basins used for the automated calibration objective

function calculation are selected from the sub-basins listed in table 3.3. The sub-basins

were chosen to represent all major land classes, and represent a variety of geographic

areas so that the automated algorithm calibrates to an objective function that represents

historic data from a variety of regions within the watershed. The sub-basins were also

chosen to have a full historic streamflow data set for the simulation period (January 1,

2002 to December 31, 2005). The sub-basins used in automated calibration are shown in

table 3.10 and figure 3.11.

Figure 3.11: Sub-basins used for automated calibration

The simulation outputs (streamflow) from the six selected sub-basins are subjected

to the daily Nash-Sutcliffe coefficient, and then incorporated into the weighted objective

function (equation 3.2) using a script called “MultiNash” (Appendix B). Although a

small portion of the watershed is represented during automated calibration, results from

several other basins will be considered for validation purposes once the calibration

process is complete.

3.3.5 Automated Calibration Results

Automated calibration was performed using the iterative process described in figure 3.10.

Although the model is calibrated using the results from the six sub-basins listed in table

3.10, model validation is considered for all sub-basins with acceptable data (table 3.8).

The manually calibrated model had a weighted (using sub-basins in table 3.10) Nash-

Sutcliffe daily coefficient of 0.669. This weighted Nash-Sutcliffe daily coefficient was

improved through the automated process to 0.743. The parameter values found through

49

the automated calibration process for each river class and land class parameter described

in section 3.2.3 are shown in table 3.11 and 3.12 respectively.

The automatic calibration was done using the weighted objective function as a

measure of model accuracy, and the parameter values found were applied across the

entire basin. Although the weighed objective function improved through automated

calibration, the success of the method is measured by considering modeling

improvements from the individual sub-basins in the model. Additionally, the Nash-

Sutcliffe monthly coefficients are used as performance metric since the automated

process measures considered only the daily measurements. The Nash-Sutcliffe daily and

monthly coefficients resulting from automated calibration are compared to the manually

calibrated values for all acceptable basins in table 3.13. Shaded rows indicate sub-basins

that were automatically calibrated.

Although only six sub-basins were automatically calibrated, improvements were

made in the Nash-Sutcliffe daily and monthly coefficients in most cases. Automated

calibration improved the model accuracy for 15 of 19 sub-basins (9 of 13 validation sub-

basins) for the daily Nash-Sutcliffe coefficient, and for 14 of 19 sub-basins (8 of 13

validation sub-basins) for the monthly Nash-Sutcliffe coefficient. Although the weighted

average showed improvement, the method is validated by the improvement of the basins

that were not considered during the automated calibration.

Finally, the pre-calibrated model results were compared to the fully calibrated

(automated) results. The Nash-Sutcliffe daily and monthly coefficients resulting from

automated calibration were compared to the pre-calibrated model for all acceptable

The automated calibration using a multi-basin approach produced improved

modeling results relative to pre-calibrated results in 17 of 19 sub-basins for the daily

Nash-Sutcliffe coefficient and 19 of 19 sub-basins for the monthly Nash-Sutcliffe

3.4 Summary

The Upper South Saskatchewan River watershed was modeled in WATFLOOD and

calibrated to a daily Nash-Sutcliffe coefficient using both manual and automated

calibration. Figure 3.12, 3.13, and 3.14 display hydrographs from the pre-calibrated

model and those produced by manual and automated calibration respectively for sub-

basin 9.

Calibration was successful in that manual calibration produced improved modeling

results in 15 of 19 sub-basins for the daily Nash-Sutcliffe coefficient and 19 of 19 sub-

basins for the monthly Nash-Sutcliffe coefficient. Automated calibration using a multi-

basin approach produced improved modeling results relative to manually calibrated

results in 15 of 19 sub-basins for the daily Nash-Sutcliffe coefficient and 14 of 19 sub-

basins for the monthly Nash-Sutcliffe coefficient. The automated calibration using a

multi-basin approach produced improved modeling results relative to pre-calibrated

results in 17 of 19 sub-basins for the daily Nash-Sutcliffe coefficient and 19 of 19 sub-

basins for the monthly Nash-Sutcliffe coefficient.

The approach was very effective in improving modeling results over the entire

watershed, producing consistent improvements in almost all of the sub-basins used for

validation. There are several potential improvements that could be made to improve the

calibration. First, more parameters could be included in the automatic calibration

process. Although this would provide the opportunity for a more accurate model, but it

54

might come at the cost of increased computational time as more model evaluations might

be required to ensure a sufficient solution has been found.

A second possible way to improve the calibration of this model would be to alter

the weighting function used for the automated calibration or to change the sub-basins

used in the calculation of “MultiNash.” Though this would not guarantee improved

modeling results, it would give insight into how the weighting function and sub-basin

selection can impact automatic calibration.

Chapter 4

Impacts of Precipitation De-clustering

The first portion of this thesis dealt with hydrologic model calibration using both manual

and automated calibration methods. This chapter applies the automatic calibration

methodology to four models, each with a precipitation data set that has been reduced

from the original set used in chapter 3. The first goal of this chapter is to determine how

removing specific rain gauges from the precipitation data set affected the calibration

potential of hydrologic models on both the local (sub-basin) and global (regional scale

watershed). The results of this study will not only provide information on the effects of

removing precipitation data, it is intended to provide insight into the potential to improve

hydrologic models by increasing the number and/or density of available meteorological

stations. Results from areas of the watershed with different spatial distributions of

precipitation gauges are also analyzed in an attempt to determine a relationship between

rain-gauge density and calibrated Nash-Sutcliffe coefficients.

The second goal of this portion of the study was to observe how parameter values

vary from the “optimum” values found from calibrating the model described in chapter 3.

Comparing how each parameter varies when the precipitation inputs are changed will

reveal how uncertainty in precipitation translates to potential uncertainty in different

parameter values.

The rain gauge data set that was used to produce the input precipitation data for the

model was reduced several times through a de-clustering method. Each time the rain

gauge set was reduced, a new input data set was interpolated (using equation 2.2 and 2.3)

and the model was re-calibrated using the method outlined in Chapter 3.

The results of this study will help to determine how removing precipitation data

points impacts hydrologic modeling calibrations. It will help to determine areas of

regional scale hydrologic models that require more precipitation gauges and areas that

56

can have use a reduced data set without significantly decreasing the accuracy of modeling

results.

4.1 De-clustering Method

De-clustering is the process of removing data points in an effort to improve the spatial

distribution of the data. De-clustering of the precipitation data reduces rain gauge density

and provides a rain gauge set that is used to create a new interpolation to be used as an

input data set.

4.1.1 Rain Gauge Removal Order

Starting with a set of rain gauges that included all 28 gauges in the study area, a

clustering index was calculated using a variation on the nearest neighbour removal order

(Ahrens, 2005) according to:

∑=

=N

iidCI

1

2 (4.1)

where CI is the clustering index, di is the distance between the selected rain gauge and the

closest neighboring rain gauge and N is the number of neighboring rain gauges used to

calculate CI. For each rain gauge, di is calculated for the closest N (4 for this study)

neighboring rain gauges and the gauge with lowest CI is removed and the process is

repeated. An example of how CI values would be calculated is shown in section 2.1.4.

The order of removal of the 28 rain gauges according to equation 4.1 is shown in

table 4.1.

57

Table 4.1 – Rain gauge removal order

2 N/A16 N/A5 N/A18 N/A

The final four gauges (2, 16, 5, and 18) listed above do not have a clustering index

because at least four other gauges are required for this calculation.

4.1.2 De-clustering Trials

De-clustering of the initial rain gauge set was done four times. Each trial removed five

rain gauges (including those removed in previous trials). Table 4.2 shows summarizes

the gauges removed each step.

58

Table 4.2: Rain gauges removed for each de-clustering trial

The rain gauge sets were interpolated to generate precipitation data for each grid

cell according to the IDW interpolation method outlined in section 2.1.3 (equation 2.2

and 2.3), with a maximum search radius implemented according to Shepard’s method

(Yoeli, 1975). The search radius selected for this interpolation was 100 km, and the

minimum number of points required for the interpolation was 1.

The locations of the rain gauges used in the complete set (used for calibration in

chapter 3) are compared to the rain gauge sets used in the de-clustering trials in figure 4.1

4.2 Calibration Results

Once the interpolation for the rain gauge set was complete, the model was run with the

new precipitation interpolations used as the input data set. The parameter values for this

first model run were the final parameter values from the automated calibration (Table

3.11 and 3.12).

As may be expected, the general trend of the pre-calibrated models was a decreased

Nash-Sutcliffe coefficient as the number of rain gauges used to interpolate the input data

was reduced. Starting from each pre-calibrated model, each of the models was calibrated

using automated calibration as described in section 3.3.

Automated calibration identified unique parameter sets for each model with de-

clustered input data sets. Parameter variation was tracked for each river and land class

parameter to determine how they varied from the “optimal” values that were found from

calibration of the complete data set. Figure 4.2 shows the parameter variation of the river

class parameters (LZF and R2) from the de-clustering trials.

Figure 4.2: River class parameter variation resulting from de-clustering trials

The values of LZF and R2 found through automated calibration of the de-clustered

models were all very similar. The river class parameters LZF and R2 control the base

flow depletion curve and the timing of the peak flows. It was expected that these values

would not vary significantly when a de-clustered precipitation set was used as the model

input since they have already been calibrated to match the shape of the base flow

depletion curve (LZF), and the timing of the peak flows (R2) of the historic data set.

They have very little to do with modeled runoff volume which is where most of the

uncertainty in the de-clustered models comes from.

Land class parameters control the magnitude of the peak flows and the volume of

runoff simulated by WATFLOOD. Different interpolations would likely lead to different

volumes of input precipitation, and thus, variation of the land class parameters optimize

the Nash-Sutcliffe coefficients was expected. Figure 4.3 shows the parameter variation

of the land class parameters (RE, RETN, MF, BASE, and FTAL) from the de-clustering

trials.

Figure 4.3: Land class parameter variation resulting from de-clustering trials

Compared to the river class parameters, the de-clustered models produced more

variation in the land class parameter values. The variation of the land class parameters

was within a reasonable range, with all parameters having variation less than one order of

magnitude, and with BASE having no variation more than two degrees Celsius.

The initial and calibrated weighted daily Nash-Sutcliffe coefficients for each trial

are shown in table 4.5.

Although the weighted daily Nash-Sutcliffe coefficients were improved for each

trial through automated calibration, analysis of the results for each sub-basin was

required to determine how precipitation de-clustering impacts modeling results on a local

and global scale. Table 4.6 and 4.7 show the daily and monthly Nash-Sutcliffe

coefficients respectively for each trial for each sub-basin. The shaded values indicate the

Two things to consider are that the results from sub-basins 16-25 had consistently

better daily and monthly Nash-Sutcliffe coefficients with the full precipitation data set

used as a model input. Additionally, the best daily and monthly Nash-Sutcliffe

coefficients for sub-basins 26-29 resulted from models that used de-clustered

precipitation data sets. Figures 4.4 and 4.5 show the average daily and monthly Nash-

Sutcliffe values for each de-clustering trial. Three values are shown: the total average for

each trial, the average value for basin 16-25, and the average value for basins 26-29.

Figure 4.7: Sub-basin 26-29 shown with full precipitation set locations

Sub-basins 16-25 (with the exception of 25) are all located in a region of the

watershed that has a very high density of rain gauges, while sub-basins 26-29 are located

just outside of the same dense region. The sub-basins located within the dense rain gauge

68

region (sub-basins 16-23) produced better modeling results when the entire rain gauge set

was used, and thus, benefited from the proximity of the gauges. The sub-basins located

just outside of the dense region (sub-basins 26-29) were heavily influenced by the

clustered points. When some of those points were removed, the precipitation

interpolations that influence these sub-basins were more balanced and the Nash-Sutcliffe

coefficients were improved.

It is apparent that some of the de-clustering trials produced certain sub-basins where

the best daily and monthly Nash-Sutcliffe values did not correspond to the model with the

most complete input data set; however, a majority of sub-basins were best represented by

the model developed with a full precipitation data set. On a global scale, the full

precipitation set produced a model with the highest average daily and monthly Nash-

Sutcliffe values.

4.3 Discussion

The primary findings resulting from the work outlined in this chapter is the relationship

between rain gauge density and calibrated model results on a local and global scale. It

was found that watershed-wide (globally), modeling results were more accurate when

more rain gauges were used for the model input. There were, however, geographic areas

of the model (local) that had improved modeling results when a de-clustered data set was

used as the input. This section discusses potential interpretations and implications of

results of the calibrations described in this chapter.

On a global scale, the results are quite straight forward to interpret. The average

Nash-Sutcliffe values of each de-clustering trial show that models with more input data

produced more accurate modeling results upon calibration. This supports the theory that

more input data will produce regional scale models with stronger predictive abilities over

the entire watershed.

69

On a local scale, the results shown in this chapter are more complex. Since some

sub-basins had the best Nash-Sutcliffe coefficients from de-clustered models, the results

require more interpretation. It should be noted that some of the more complex results

might be due to poor optimizer performance as the calibration method used is not perfect

(nor is any). Additional optimization trials might lead to significantly better results. The

sub-basins previously shown in figure 4.7 are all located in a geographic region with a

low local rain gauge density and no rain gauges actually lie within the sub-basin

boundaries. The best modeling results were produced by using a de-clustered data set. If

this study was done in reverse (i.e. starting with 8 rain gauges and increasing to 28), no

rain gauges are added within the sub-basin limits, and thus, there is no guarantee that

more data would improve modeling results.

The sub-basins previously shown in figure 4.6, which are located in a region with a

higher local rain gauge density, suffered from de-clustering. Again, if the study was

performed in reverse, several rain gauges would have been added within the limits of the

displayed sub-basins, and improved modeling results would have been expected.

The local rain gauge density in this study was found to be very important to

modeling results when the rain gauges were within the limits of the sub-basin being

modeled. When rain gauges are added outside the limits of a sub-basin, it is very difficult

to predict the effect it will have on modeling results.

This case study shows that portions of the model (sub-basins 26-29) with low local

rain gauge density can still produce reasonably accurate results (0.33 to 0.56 daily Nash-

Sutcliffe coefficients for this study as shown in table 4.6); however, sub-basins located

within geographic regions of higher rain gauge density (sub-basins 16-25) produced

significantly better and more consistent results (0.56 to 0.81 daily Nash-Sutcliffe

coefficients as shown in table 4.6). For a regional scale model it would be very difficult

to trust modeling results fuelled by a scarce data set regardless of the quality of the

model’s predictive power. With good values determined for the river class parameters,

the uncertainty in precipitation mainly translates to uncertainty in the land class

70

parameter values and can offset inaccurate precipitation input data produced by poor

local rain gauge density.

The results presented in this chapter are difficult to generalize to hydrologic models

in general, as the site was quite data poor with respect to available rain gauge data.

Without using an initial data set that contains consistently spaced rain gauges, the

importance of the rain gauge density for each trial can be very difficult to interpret. The

ideal scenario to test the effects of de-clustering would involve having a rain gauge

located in every grid cell in the study area. Gauges would then be removed according to

equation 4.1, and the model would be re-calibrated. Starting off the scenario with equally

spaced rain gauges would give more importance to the rain gauge density values when

compared to the resulting Nash-Sutcliffe coefficients of each de-clustered model.

A limitation that is always present in hydrologic modeling is the error in the

recorded historic precipitation data at each individual rain gauge, and this error can be

compounded when less data is available. While each rain gauge is likely to have some

error in each recorded precipitation event, the errors in models with a high density of data

points can even each other out when spatially interpolated. With a low density model

that essentially becomes subjected to a nearest neighbour interpolation, huge portions of

the model are fuelled by an input that is based on only one rain gauge that may have

significant error. The potential for this compounded error is another reason why models

with low rain gauge density are very difficult to trust.

The value of an added data point is only as good as the proximity it has to the sub-

basin being studied. In a regional scale model, with many sub-basins there are bound to

be geographic locations of the watershed that are relatively data-poor with regards to rain

gauge availability. To trust the results of a regional scale model that has parameter

flexibility similar to the WATFLOOD model used in this case study, the local rain gauge

density must be sufficient and at least partially within the boundaries of the sub-basins

considered. Though there is evidence that some data points can be removed without

significantly decreasing modeling accuracy in geographic locations with high rain gauge

71

density, the results of this chapter show that the best results for a regional scale model

will come from using all available precipitation inputs.

72

Chapter 5

Summary

This primary purpose of this thesis was to present a general approach to calibrating a

regional scale hydrologic model using a WATFLOOD model of the upper South

Saskatchewan River watershed as a case study. Initially, manual calibration was

described and performed on several sub-basins within the watershed. Using the manual

calibration results as a basis for automated calibration, a multi-basin automated

calibration approach was developed and applied to the model. The results demonstrated

that both methods were effective tools for improving modeling results. Not only were the

daily Nash-Sutcliffe coefficients of the sub-basins subjected to calibration all improved,

the results from x of y sub-basins used for validation were also improved. Additionally,

improvement in the monthly Nash-Sutcliffe coefficient was observed for every sub-basin

in the calibrated model relative to the pre-calibrated model. Overall, the average daily

Nash-Sutcliffe coefficient of the 19 calibration and validation sub-basins improved from

an initial value of 0.17 before calibration to 0.43 after manual calibration and then to 0.56

after refinements with automatic calibration.

The calibration method was applied to four models that used de-clustered

precipitation data as their input with the purpose of determining the effects of rain gauge

density on modeling results. The results of the four calibrations, based on the daily and

monthly Nash-Sutcliffe coefficients of all 19 sub-basins, were compared to the initial

calibrated model that used the entire precipitation data set. Of the 19 sub-basins

considered, 11 of had the best daily Nash-Sutcliffe coefficients in the model that used the

entire precipitation data set, and the best values for the remaining 8 sub-basins were

produced from a de-clustered model.

Calibration of the de-clustered models produced almost no variation in the river

class parameters from the values found during the calibration of the initial model.

Variation was found in the land class parameter values, but it was within a reasonable

73

range, with optimal parameters being modified less than one order of magnitude from

their original values. Because the variation in the river class parameters was so low

compared to the land class parameters, future de-clustering studies should consider

placing a priority on re-calibrating land class parameters and not river class parameters.

De-clustered models create uncertainty in precipitation volume which translates to

uncertainty in land class parameter values since they have a much higher influence on

runoff volumes than river class parameters.

In general, models that used more input data produced better modeling results than

de-clustered models; however, de-clustered models did produce better results in some

cases. Because the variation of the parameter values was within reasonable ranges for

each of these improved cases, extended study into the effects of precipitation gauge

density on modeling accuracy may provide stronger conclusions on how input

precipitation data can be modified or supplemented to improve modeling results.
