TauDEM 5.1

TauDEM is a suite of Digital Elevation Model (DEM) tools for the extraction and analysis of hydrologic information from topography. This tool can calculate flow paths (directions) and slopes, as well as contributing area using single and multiple flow direction methods.

The app provides multiple methods for the delineation of stream networks including topographic form-based methods sensitive to spatially variable drainage density, objective methods for determination of the channel network delineation threshold based on stream drops, and specialized functions for terrain analysis.
