TauDEM (Terrain Analysis Using Digital Elevation Models) is a suite of
|
|
|
|
|
Digital Elevation Model (DEM) tools for the extraction and analysis of
|
|
|
|
|
hydrologic information from topography as represented by a DEM. TauDEM
|
|
|
|
|
provides the following capability:

flooding approach

|
|
* 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
|
|
|
|
|
* Delineation of watersheds and subwatersheds draining to each stream
|
|
|
|
|
segment and association between watershed and segment attributes for
|
|
|
|
|
setting up hydrologic models

Note TauDEM also works fine with MPICH, so if you have it installed it
|
|
|
|
|
is not necessary to install OpenMPI.
