WMS is a comprehensive software package for developing computer simulations of watersheds. The WMS software package is used at hundreds of sites around the world. These sites include federal, state, private, and educational institutions. WMS is the new standard for watershed modeling.

WMS can be used for:

1. Visualizing and delineating sub-basins in a watershed
2. Computing hydrologic and geometric parameters for each sub-basin
3. Defining hydrologic parameters that cannot be automatically computed
4. Running several hydrologic models, including HEC-1, HMS, TR-20, TR-55, the Rational Method, F0601, and the National Flood Frequency Method
5. Viewing the results of these hydrologic models
6. Importing and exporting Geographic Information System (GIS) data

WMS is distributed commercially through Environmental Modeling Systems Incorporated (EMS-I). EMS-I also sponsors regularly scheduled training courses featuring WMS. If you are interested in downloading, evaluating, or purchasing WMS, please visit the EMS-I site.
