Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Model type Tool Model part of larger framework Note on status model Date note status model Incorporated models or components: Spatial dimensions 2D Spatial extent Watershed-Scale Model domain Hydrology One-line model description A suite of Digital Elevation Model (DEM) tools for the extraction and analysis of hydrologic information from topography as represented by a DEM. TauDEM 5 is a new version implemented to take advantage of parallel processing Extended model description TauDEM provides the following capability: •Development of hydrologically correct (pit removed) DEMs using the flooding approach •Calculates flow paths (directions) and slopes •Calculates contributing area using single and multiple flow direction methods •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 •Specialized functions for terrain analysis Details of new parallel Version 5.0 of TauDEM •Restructured into a parallel processing implementation of the TauDEM suite of tools •Works on Windows PCs, laptops and UNIX clusters •Multiple processes are not required, the parallel approach can run as multiple processes within a single processor •Restructured into a set of standalone command line executable programs and an ArcGIS toolbox Graphical User Interface (GUI) •Command line executables are: -Written in C++ using Argonne National Laboratory's MPICH2 library to implement message passing between multiple processes -Based on single set of source code for the command line execuables that is platform independent and can be compiled for both Window's PC's and UNIX clusters Keywords: hydrologivally corrected DEM, watershed, Name David Tarboton Type of contact Model developer Institute / Organization Utah State University Postal address 1 8200 Old Main Hill Postal address 2 Town / City Logan Postal code 84322 State Utah Country United States Email address dtarb@usu.edu Phone 4357973172 Fax Supported platforms Unix, Linux, Mac OS, Windows Other platform Programming language C++ Other program language Code optimized Multiple Processors Multiple processors implemented Nr of distributed processors Nr of shared processors Start year development 1997 Does model development still take place? Yes If above answer is no, provide end year model development Code development status When did you indicate the 'code development status'? Model availability As code Source code availability (Or provide future intension) Through web repository Source web address http://hydrology.usu.edu/taudem/taudem5/index.html Source csdms web address Program license type GPL v2 Program license type other Memory requirements Depends on data Typical run time Depends on data 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 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: Model website if any http://hydrology.usu.edu/taudem Model forum / discussion board Comments This part will be filled out by CSDMS staff OpenMI compliant No but possible BMI compliant No but possible WMT component No but possible PyMT component Is this a data component Can be coupled with:
