HEC-RAS
Hydrologic Engineering Center's (CEIWR-HEC) River Analysis System (HEC-RAS). HEC-RAS is an integrated system of software, designed for interactive use in a multi-tasking environment. This software allows the user to perform one-dimensional steady flow, one and two-dimensional unsteady flow calculations, sediment transport/mobile bed computations, and water temperature/water quality modeling. The HEC-RAS modeling system was developed as a part of the Hydrologic Engineering Center's "Next Generation" (NexGen) of hydrologic engineering software. The system is comprised of a graphical user interface (GUI), separate analysis components, data storage and management capabilities, graphics, mapping and reporting facilities.
It is a flow hydraulic model designed to aid hydraulic engineers in channel flow analysis and floodplain determination. The results of the model can be applied in floodplain management and flood insurance studies. This software allows the user to perform one-dimensional steady flow, one and two-dimensional unsteady flow calculations, sediment transport/mobile bed computations, and water temperature/water quality modeling.
