Abstract
Generalized Terrain-Based Flow Analysis of Digital Elevation Models
Track: Water Resources
Author(s): Kimberly Schreuders, Matthew Baker, David Tarboton, Daniel Watson
Digital Elevation Models (DEMs) of topography are widely used to derive information for the modeling of hydrologic processes. We present a general method for recursive flow analysis that builds upon the D-infinity model for the representation of downslope flow used in the Terrain Analysis Using Digital Elevation Models (TauDEM) package to enable the calculation of a rich set of flow-based derivative surfaces. This paper will present some new tools that have been added to TauDEM to extend its capability for hydrologic analysis using these recursive flow analysis methods. These new tools have been packaged as an ArcGIS toolbox so that they may be used in Model Builder and within the ArcGIS geoprocessing framework. Algorithms for some of these tools have also been modified to take advantage of parallel processing architectures, thereby enabling the rapid processing of large datasets.
