What is HEC-HMS?

The Hydrologic Modeling System (HEC-HMS) is a free, comprehensive software package developed by the U.S. Army Corps of Engineers (USACE). It is the standard tool for simulating precipitation-runoff processes of dendritic watershed systems throughout the United States.

  • Rainfall-runoff simulation for single storms or continuous events
  • Multiple loss methods including SCS Curve Number and Green-Ampt
  • Channel and reservoir routing for flood analysis
  • GIS integration through HEC-GeoHMS
