  2. MODFLOW - Wikipedia

    en.wikipedia.org/wiki/MODFLOW

    MODFLOW-OWHM [11] (version 1.00.12, October 1, 2016), The One-Water Hydrologic Flow Model (MODFLOW-OWHM, MF-OWHM or One-Water [12]), developed cooperatively between the USGS and the U.S. Bureau of Reclamation, is a fusion of multiple versions of MODFLOW-2005 (NWT, LGR, FMP, SWR, SWI) into ONE version, contains upgrades and new features and ...

  3. Groundwater model - Wikipedia

    en.wikipedia.org/wiki/Groundwater_model

    Groundwater models are used in various water management plans for urban areas. As the computations in mathematical groundwater models are based on groundwater flow equations, which are differential equations that can often be solved only by approximate methods using a numerical analysis, these models are also called mathematical, numerical, or ...

  4. Hydrological model - Wikipedia

    en.wikipedia.org/wiki/Hydrological_model

    A two-dimensional scale model of an aquifer. Groundwater flow can be visualized using a scale model built of acrylic and filled with sand, silt, and clay. [3] Water and tracer dye may be pumped through this system to represent the flow of the simulated groundwater.

  5. GMS (software) - Wikipedia

    en.wikipedia.org/wiki/GMS_(software)

    A study published in the Journal of Agricultural and Applied Economics in August 2000 stated that "GMS provides an interface to the groundwater flow model, MODFLOW, and the contaminant transport model, MT3D. MODFLOW is a three-dimensional, cell-centered, finite-difference, saturated-flow model capable of both steady-state and transient analyses.

  6. Numerical modeling (geology) - Wikipedia

    en.wikipedia.org/wiki/Numerical_modeling_(geology)

    One of the well-known programs in modeling groundwater flow is MODFLOW, developed by the United States Geological Survey. It is a free and open-source program that uses the finite difference method as the framework to model groundwater conditions.

  7. Groundwater flow equation - Wikipedia

    en.wikipedia.org/wiki/Groundwater_flow_equation

    The transient flow of groundwater is described by a form of the diffusion equation, similar to that used in heat transfer to describe the flow of heat in a solid (heat conduction). The steady-state flow of groundwater is described by a form of the Laplace equation, which is a form of potential flow and has analogs in numerous fields.

  8. Hydrogeology - Wikipedia

    en.wikipedia.org/wiki/Hydrogeology

    MODFLOW is a well-known example of a general finite difference groundwater flow model. It is developed by the US Geological Survey as a modular and extensible simulation tool for modeling groundwater flow. It is free software developed, documented and distributed by the USGS.

  9. Hydrological transport model - Wikipedia

    en.wikipedia.org/wiki/Hydrological_transport_model

    River in Madagascar relatively free of sediment load. An hydrological transport model is a mathematical model used to simulate the flow of rivers, streams, groundwater movement or drainage front displacement, and calculate water quality parameters.
