About HEC-RAS
HEC-RAS is river-analysis software for modeling water flow through river systems and open channels. It supports one-dimensional steady-flow calculations and one- and two-dimensional unsteady-flow calculations. These methods allow users to examine river behavior under different flow conditions and channel configurations. The system also supports sediment transport and mobile-bed computations, as well as water-temperature and water-quality modeling. This makes HEC-RAS relevant to hydraulic and environmental studies involving rivers and open channels. The supplied information does not specify input formats, calibration tools, or mapping capabilities. Results depend on the data, geometry, and assumptions used in the model. These flow models support analysis of river and channel behavior under different conditions.
