HEC-RAS 6.5

Provides analysis over steady and unsteady water flow, as it executes one-dimensional calculations for steady flow and two-dimensional for unsteady flows. Also, it does mobile bed computations and takes the water temperate. Sediment transport is also analyzed.

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