The HEC-HMS model simulates rainfall-runoff processes in a dendritic (single outlet) watershed. The model simulates the individual fluxes of the hydrologic cycle, such as snow-melt, infiltration, evapotranspiration, base flow, and channel routing. The model is applicable to a number of analyses, such as flood studies, reservoir spillway design, streamflow forecasting, urban drainage, future urbanization impacts, water quality, erosion and sediment transport.
Key features of the model include multiple methods to model physical processes of runoff where the user selects an appropriate method based on data availability and requirements; calibration using an optimization algorithm; uncertainty analysis; and GIS capabilities. A companion model, HEC-GeoHMS, allows for GIS analysis with the model.
