INTRODUCTION
In order to improve their understanding of the environment, water resources engineers use measurements of
variables like temperature and flow rate that are measured through time. By analyzing these time series of data,
they can spot trends and make inferences about how a hydrologic system responds to events like storms or
construction in a sensitive watershed. Critical to this analysis is the ability to find time series data and put them in
a spatial context.
HydroDesktop is a free and open source Hydrologic Information Systems (HIS) application that helps users
discover, use, and manage hydrologic time series data. It includes data query, download, visualization, graphing,
analysis and modeling capabilities. HydroDesktop use open source GIS components called DotSpatial and and open
source relational database called SQLite to provide an information base with which users can efficiently collect and
synthesize large quantities of hydrologic data. HydroDesktop is designed to exploit the utility of WaterOneFlow
Web services developed by the Consortium of Universities for the Advancement of Hydrologic Science, Inc.
(CUAHSI) Hydrologic Information Systems project (CUAHSI‐HIS). The result is a spatially‐enabled system that
facilitates the aggregation of time series of observational data describing the water environment.

GOALS AND OBJECTIVES
The goal of this exercise is to introduce you to the tools and functions available in HydroDesktop that allow you to
search for and synthesize hydrologic time series data in an area of interest. This exercise will teach you how to find
and obtain streamflow data in Texas, visualize the data and then finally communicate your findings in a printable
layout.
Objectives for this exercise include:
Find where streamflow is measured in Texas.
Download streamflow for a watershed in Texas.
Visualize time series data in tables and graphs.
Export time series data for use in other programs.
Create a printable map and graph to communicate your results.
COMPUTER AND DATA REQUIREMENTS
HydroDesktop is currently designed to run only on a Windows operating system such as Windows XP or Windows
7. To carry out this exercise, you will need the latest version of HydroDesktop, which is HydroDesktop 1.1 Beta
RC6 at the time of this writing. Because HydroDesktop’s functionality continues to grow, the installer is periodically
updated. Check back often for the latest version of HydroDesktop. You will also need an Internet connection since
you will be accessing live online data.
It is expected that you will do this exercise on your own computer. Because the software is still being evolved, it
is not installed in the computer labs being used for ArcGIS in this course, and you will not be able to install it there
because you do not have administrator privileges on the laboratory computers.
To install HydroDesktop:
1. In a Web browser, navigate to http://www.hydrodesktop.org (this converts automatically to
http://hydrodesktop.codeplex.com/ ).
2. Click the Download link on the right to download the installer for version 1.1 Beta RC6, as shown
below.
