Purpose
The purpose of this document is to introduce Hydrologic Terrain Analysis in ArcGIS using the TauDEM
toolbox. This guide is not intended to be comprehensive in documenting the use and functionality of
TauDEM. Rather it is intended as a brief introduction to guide a reader through the initial steps of
installing TauDEM obtaining data and running some of the more important functions required to
delineate a stream network. Comprehensive documentation on the use of each TauDEM function is
given in the online help that is part of the program (that will be introduced in this quick start guide).
TauDEM (Terrain Analysis Using Digital Elevation Models) is a set of Digital Elevation Model (DEM) tools
for the extraction and analysis of hydrologic information from topography as represented by a DEM.
This is software developed at Utah State University (USU) for hydrologic digital elevation model analysis
and watershed delineation and may be obtained from
