3D view. HEC-RAS is simulation software used in computational fluid dynamics – specifically, to model the hydraulics of water flow through natural rivers and other channels.. The program was developed by the United States Army Corps of Engineers in order to manage the rivers, harbors, and other public works under their jurisdiction; it has found wide acceptance by many others since its ...
The HEC-RAS model calculated that the water backs up to a height of 9.21 meters at the upstream side of the sluice gate, which is the same as the manually calculated value. Normal depth was achieved at approximately 1,700 meters upstream of the gate. HEC-RAS modeled the hydraulic jump to occur 18 meters downstream of the sluice gate.

HEC-HMS is a product of the Hydrologic Engineering Center within the U.S. Army Corps of Engineers. The program was developed beginning in 1992 as a replacement for HEC-1 which has long been considered a standard for hydrologic simulation.
Hydrodynamic models, such as the Hydrologic Engineering Center's River Analysis System (HEC-RAS) or the MIKE suite of models, simulate water flow and its interaction with the surrounding environment, providing detailed predictions of flood extent, depth, and velocity.

HEC-RAS, [61] the Hydraulic Engineering Center model, is among the most popular software, if only because it is available free of charge. Other models such as TUFLOW [62] combine 1D and 2D components to derive flood depths across both river channels and the entire floodplain.
The input file can include data describing network topology, water consumption, and control rules, and is supported by many free and commercial modeling packages. While EPANET is used as the computational engine for most water distribution system models, most models are developed and maintained in hydraulic modeling packages based on EPANET's ...
