Find out how the latest HEC-HMS developments are taking advantage of vast amounts of newly available meteorological data to provide increasingly realistic simulations of the rainfall-runoff process. The U.S. Army Corps of Engineers Hydrologic Engineering Center’s Hydrologic Modeling System (HEC-HMS) simulates the entire hydrologic process. We invite you to join this free webinar demonstrating the process of building and running a model in HEC-HMS and providing an overview of new features and capabilities.

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.  For more information, click here.
