The new HEC-HMS provides almost all of the same simulation capabilities, but has modernized them with advances in numerical analysis that take advantage of the significantly faster desktop computers available today. It also includes a number of features that were not included in HEC-1, such as continuous simulation and grid cell surface hydrology.
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 models were created with the software Surface-Modeling System (SMS) of Aquaveo LLC" (Gerstner, Belzner, and Thorenz, 976). [ 17 ] This article "describes the mathematical formulation, numerical implementation, and input specifications of rubble mound structures in the Coastal Modeling System (CMS) operated through the Surface-water Modeling ...
HEC-1 is software that was developed by the US Army Corps of Engineers [1] to estimate river flows as a result of rainfall. It was written in the FORTRAN language and until 1984 could only be run on a mainframe computer. When desktop computers became popular the program was ported to the PC. [2]
The 1-D equations are used extensively in computer models such as TUFLOW, Mascaret (EDF), SIC (Irstea), HEC-RAS, [5] SWMM5, InfoWorks, [5] Flood Modeller, SOBEK 1DFlow, MIKE 11, [5] and MIKE SHE because they are significantly easier to solve than the full shallow-water equations.
The Hollerith Electronic Computer (HEC) was produced by the British Tabulating Machine Company (BTM) and was based on a design by Professor Andrew Booth of Birkbeck College, London. [1] It was Britain's first mass-produced business computer.
