HEC-RAS is designed to perform hydraulic calculations for a full network of natural and constructed channels. At its core, the software allows users to model steady and unsteady flow in both 1D and 2D domains. Its applications are diverse, ranging from standard floodplain encroachment studies to the analysis of complex dam break scenarios and the evaluation of levee overtopping. : At least 1 GB of free hard
Until that day arrives, do not treat HEC-RAS like a phone app where you can roll back to "how it used to be." Treat it like a scientific instrument. You calibrate to the instrument you have.
Historically, users had to calculate rainfall runoff externally in hydrologic models like HEC-HMS and import the hydrographs. HEC-RAS 6.0 allows you to apply spatial precipitation grids and wind forces directly onto 2D flow areas. It also features built-in infiltration methods, including: Deficit and Constant SCS Curve Number Green and Ampt 2. HEC-RAS Mapper Overhaul
