Hydrologic Engineering Center Hydrologic Modeling System, HEC-HMS: Interior Flood Modeling
Publication: World Environmental and Water Resources Congress 2008: Ahupua'A
Abstract
The Hydrologic Modeling System (HEC-HMS) is designed to simulate the precipitation-runoff processes of dendritic watershed systems. It is designed to be applicable in a wide range of geographic areas for solving the widest possible range of problems. This includes large river basin water supply and flood hydrology, and small urban or natural watershed runoff. Hydrographs produced by the program are used directly or in conjunction with other software for studies of water availability, urban drainage, flow forecasting, future urbanization impact, reservoir spillway design, flood damage reduction, floodplain regulation, and systems operation. Since its last release in 2005, the HEC-HMS software has incorporated many enhancements. These include reservoir simulation, lateral weirs, pump stations, channel loss methods, automatic areal rainfall adjustment, gridded continuous simulation methods, snowmelt and improved computational speed among many others. Combining the capabilities of the reservoir, pump stations and diversions has allowed it be used for modeling interior drainage situations.
