Webinar: Modelling with HEC-HMS

An introduction to rainfall-runoff modeling considerations, including sensitivities to catchment parameters. We will highlight updated features that allow GIS-based rainfall-runoff modelling and provide a walk-through of a basic model setup.

The Hydrologic Modeling System (HEC-HMS) is a free program developed by the U.S. Army Corps of Engineers. HEC-HMS simulates the complete hydrologic processes of dendritic watershed systems including infiltration, unit hydrographs, and hydrologic routing. HEC-HMS also accounts for evapo-transpiration, snowmelt, and soil moisture and can be used in conjunction with other software for studies of water availability, urban drainage, flow forecasting, urbanisation impacts, reservoir spillway design, flood damage reduction, floodplain regulation, and systems operation.
