WMS Public Domain Version

The Watershed Modeling System (WMS) can now be obtained for public domain use - free of charge!  This freeware version of the software will allow anyone to set up and execute a hydrologic model using the schematic set up option in the Hydrologic Modeling Module of WMS.  Features of the public domain version include:

 Choose to use HEC-1 (HEC-HMS), TR-20, TR-55, NFF, MODRAT, or Rational Method
     for hydrologic analysis.
 Create a complete model schematic including diversions and reservoirs with the simple
     ``hydrologic tree" tools in WMS.
 Use the full graphical interface to each model to enter model parameters, execute the
     model, and view results.
 The freeware version of WMS will increase your productivity by eliminating the need to learn
     complex file formats required for set up of the models listed above.  Further, the simple
     graphical representation will allow you and your clients to visualize the layout of the watershed
