SOFTWARE COVERED

HEC-RAS

The HEC-RAS software was developed at the Hydrologic Engineering Center (HEC), which is a division of the Institute for Water Resources (IWR), U.S. Army Corps of Engineers. The software was designed by Mr. Gary W. Brunner, leader of the HEC-RAS development team.

This software  allows you to perform one-dimensional steady, one and two dimensional unsteady flow hydraulics, sediment transport/mobile bed computations, water temperature modeling, and generalized water quality modeling

HEC-RAC is used in stream investigation for various purposes including Calculation of flood levels of waterways, Flood hazard mapping, Floodplain management, etc.

Key points about software: Supported by Corps of Engineers, Public Domain / Free / Widely used, Continuing Improvement, Graphical Abilities/GIS tool/Online support, Good Documentation
