WMS (Watershed Modeling System) is a complete program for developing watershed computer simulations. WMS supports lumped parameter, regression, and 2D hydrologic modeling of watersheds, and can be used to model both water quantity and water quality. It also supports river hydraulic and storm drain models. Currently supported models include HEC-1, HEC-RAS, HEC-HMS, TR-20, TR-55, NFF, Rational, MODRAT, HSPF, CE-QUAL-W2, GSSHA, SMPDBK, and other models.


WMS was initially developed by the Engineering Computer Graphics Laboratory at Brigham Young University in the early 1990s on Unix workstations. The development of WMS was funded primarily by The United States Army Corps of Engineers. It was later ported to Microsoft Windows platforms in the mid 1990s. WMS 6.0 (2002) was the last supported version for HP-UX, IRIX, DEC-OSF, and Solaris platforms.

Development of WMS was done by the Environmental Modeling Research Laboratory (EMRL) at Brigham Young University until April, 2007. At this time, the main software development team at EMRL entered private enterprise as Aquaveo, LLC.
