Describe input parameters	Digital elevation model
Input format	Binary
Other input format	GeoTIFF and Shapefiles
Describe output parameters	Hydrologic information derived from DEM
Output format	Binary
Other output format	GeoTIFF and Shapefiles
Pre-processing software needed?	No
Describe pre-processing software	TauDEM is essentially preprocessing software for hydrologic use of Digital Elevation Models
Post-processing software needed?	No
Describe post-processing software
Visualization software needed?	Yes
If above answer is yes	ESRI
Other visualization software	Any software that can visualize GeoTIFF and shapefiles can visualize the output

Describe processes represented by the model	Flow processes that are driven by the topographic gradient
Describe key physical parameters and equations	Elevation, slope and contributing area related quantities
Describe length scale and resolution constraints	Applies to any resolution topographic grid, though is most sensible for grids with resolution from 2 to 50 m.
Describe time scale and resolution constraints	This is a static model so there is no time scale or resolution
Describe any numerical limitations and issues	Presently limited to grids up to 4GB

Describe available calibration data sets	This is not a model with adjustable parameters so calibration is not required. Example datasets are available
Upload calibration data sets if available:
Describe available test data sets	The Logan River DEM is a small test dataset useful for learning how to use the software
Upload test data sets if available:	Media:LoganDemo.zip
Describe ideal data for testing

Do you have current or future plans for collaborating with other researchers?	Yes

Is there a manual available?	Yes
Upload manual if available:
