The Watershed Modeling System (WMS) is a comprehensive environment for hydrologic analysis developed by the Environmental Modeling Research Laboratory (EMRL) at Brigham Young University in cooperation with the Coastal and Hydraulics Laboratory (Cl-IL) of the U.S. Army Engineer Research and Development Center (ERDC). WMS merges information from digital terrain models and GIS data sources to generate the model structure and parameters for a variety of watershed models. The watershed models that are supported in the WMS include traditional lumped parameter rainfall-runoff models such as HEC- 1 and TR-20, the CASC2D distributed parameter watershed model, and newly developed support of the HSPF model. With WMS, the modeler can easily create an input file for the chosen model, run the model, view the model output, and make adjustments during the calibration process using the extensive set of tools provided in the system.
