For details on how to use the Channel Design/Modifications Capabilities in HEC-RAS, please review Chapter 13 of the User’s Manual. The tool labeled Channel Modification (original) is the original channel modification tool developed for HEC-RAS. Log in to either your Dev/Test system as user fews.Ĭhannel Design/Modification is a new tool for HEC-RAS version 4.0. When the program opens, the main HEC-RAS window will pop up on your desktop: Many of the program features may be selected using the File, Edit, Run, or View menus. To start the HEC-RAS program, double-click on the HEC-RAS 3.1.3 icon located on your desktop, or go to the Start menu and click on all programs, HEC, HEC-RAS, HEC-RAS 3.1.3. HEC-RAS supports multi-tasking, multi-user network environment which means if in your office you have a. HEC-RAS is a computer program/software that allows you to perform one-dimensional steady and unsteady flow river hydraulics calculation including modeling and analysis.

Hydraulic Engineering Center (HEC) is situated in Davis, California, USA. Then the program starts using the flow rates entered for the first two hours. In this example, HEC-RAS forces the stage to be 108 feet until the simulation begins. An example of an Internal Boundary Stage and Flow Hydrograph (from the HEC-RAS User’s Manual) is shown above.
