HEC-RAS (River Analysis System) is an integrated system of software, designed for interactive use in a multi-tasking environment. The system is comprised of a graphical user interface (GUI), separate hydraulic analysis components, data storage and management capabilities, graphical and tabular output, and reporting facilities. HEC RAS (HEC, 1996) is the successor to the current steady-flow HEC-2 (HEC, 1991) Water Surface Profiles Program. The capabilities of the current version of HEC-RAS will be described.
