Hydrologic Engineering Center's (CEIWR-HEC) River Analysis System (HEC-RAS)

HEC-RAS 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.

HEC-RAS is designed to perform one and two-dimensional hydraulic calculations for a full network of natural and constructed channels. The following is a description of the major capabilities of HEC-RAS.

• User Interface
• Hydraulic Analysis Components
• Data Storage and Management
• Graphics and Reporting
• RAS Mapper
