The Hydrologic Engineering Center's (HEC) River Analysis System (HEC-RAS) software allows the user to perform one-dimensional (1D) steady flow, and 1D and two-dimensional (2D) unsteady flow river hydraulics calculations. HEC-RAS is an integrated system of software, designed for interactive use in a multi-tasking, multi-user network environment.

USDA‐ARSBank Stability and Toe Erosion Model (BSTEM)in HEC‐RAS User Manual ‐Draft v 1 Background HEC‐RAS has included mobile bed capabilities since version Thesecapabilities have followed the HEC‐6 approach that computes vertical bed changes in response to dynamic. HEC-RAS has been developed for the U.S. Army Corps of Engineers (USACE). However, software developed at the Hydrologic Engineering Center is made available to the public whenever appropriate. Use is not restricted and individuals outside of USACE may use the program without charge. HEC will not provide user assistance or support for this software to non-USACE users. Step 2 - Creating RAS geometry. Step 3 - Add river attributes. Step 4 - Creating RAS mapper. Step 5 - Run HEC-RAS model. Step 6 - Export HEC-RAS output. Step 7 - Mapping inundated areas in HEC-RAS. Introduction. The goal of this Flood Hazard Mapping Recommended Practice is to evaluate the possible inundation extent in a river reach using the.
