Introduction to Kenue

• Formerly called EnSim Hydrologic• Developed at the National Research Council (NRC)• Integration of environmental data, GIS and model data.• Data preparation, analysis, and visualization for

hydrologic modellers • Pre- & post-processing for hydrological models

(WATFLOOD and HBV-EC) – Including creations of MAP file, used to create SHD file required

by MESH, SPS

• FREE- available through NRC-CHC website

Page 10 – March-6-14

Data Views- Report View

• Can create templates for reporting

Page 11 – March-6-14

Kenue Native Formats

• ASCII and binary file formats are well-documented in Green Kenue manual

• Code for reading & writing Green Kenue native files is available upon request

– Users can use Green Kenue as a data-preparation and visualization tool for their own models

Key Features- DEM Processing

• Drainage area delineation, stream delineation– Allows for artificial diversions

• Suite of sophisticated basin metrics and DEM analysis tools

Page 13 – March-6-14

• Calculation of % land class

Key Features- GeoTIFF Processing

Breakdown by basin Breakdown by gridcell

% Forest

Page 14 – March-6-14

Key Features: GeoTIFF draping

• GeoTIFF can be draped over a DEM for 3D visualization of landscape

Page 15 – March-6-14

Key Features: Manipulation of gridded data• Support for fst, GRIB1 and GRIB2 (including rotated lat-

long)• Perform calculations on time-varying gridded data:

– Temporal maximum, minimum, range, sum, mean, standard deviation

• Calculator Tool can perform computations on gridded data sets (single frame or time-varying)

• Extract areal information (i.e. basin-wide sums, averages, min, max)

Key Features- Environmental Databases

• HYDAT (Water Survey of Canada’s published hydrometric data)

– Microsoft Access mdb file

• Canadian Daily Climate Data (CDCD)• North American Regional Reanalysis (NARR)• Python scripting capabilities

Page 19 – March-6-14

Key Feature- python scripting

• New feature (likely won’t be included in public version)• Allows access to GreenKenue libraries through python

scripts• Allow automation of all functions currently available in
