  2. HEC-RAS - Wikipedia

    en.wikipedia.org/wiki/HEC-RAS

    HEC-RAS has merits, notably its support by the US Army Corps of Engineers, the future enhancements in progress, and its acceptance by many government agencies and private firms. It is in the public domain and peer-reviewed, and available to download free of charge from HEC's web site.

  3. Standard step method - Wikipedia

    en.wikipedia.org/wiki/Standard_Step_Method

    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.

  4. Shallow water equations - Wikipedia

    en.wikipedia.org/wiki/Shallow_water_equations

    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.

  5. HEC-HMS - Wikipedia

    en.wikipedia.org/wiki/HEC-HMS

    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.

  6. EPANET - Wikipedia

    en.wikipedia.org/wiki/EPANET

    EPANET's computational engine is available for download as a separate dynamic link library for incorporation into other applications. [7] The source code for EPANET 2 is available on the EPA's EPANET website. [8] In 2012, Baseform released a rewrite of the EPANET toolkit in Java under the GNU GPLv3 license. [9]

  7. SMS (hydrology software) - Wikipedia

    en.wikipedia.org/wiki/SMS_(hydrology_software)

    SMS (Surface-water Modeling System) is a complete program for building and simulating surface water models from Aquaveo. It features 1D and 2D modeling and a unique conceptual model approach.

    The last image we have of Patrick Cagey is of his first moments as a free man. He has just walked out of a 30-day drug treatment center in Georgetown, Kentucky, dressed in gym clothes and carrying a Nike duffel bag.

  9. Flood forecasting - Wikipedia

    en.wikipedia.org/wiki/Flood_forecasting

    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.
