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 ...
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.
Groundwater models may be used to predict the effects of hydrological changes (like groundwater pumping or irrigation developments) on the behavior of the aquifer and are often named groundwater simulation models. Groundwater models are used in various water management plans for urban areas. As the computations in mathematical groundwater ...
MODFLOW code discretizes and simulates an orthogonal 3-D form of the governing groundwater flow equation. However, it has an option to run in a "quasi-3D" mode if the user wishes to do so; in this case the model deals with the vertically averaged T and S , rather than k and S s .
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.
Visual MODFLOW (VMOD) is a graphical interface (GUI) for the open source groundwater modeling engine MODFLOW. VMOD was developed by Waterloo Hydrogeologic and first released in 1994, the first commercially available GUI for MODFLOW. In May 2012 a .NET version of the software was rebranded as Visual MODFLOW Flex. The program includes proprietary ...
The company first released FLOWPATH, which—at the time—was the first fully integrated graphical groundwater modelling software. In the fall of 1993, Waterloo Hydrogeologic became incorporated (changing their name to Waterloo Hydrogeologic Inc or WHI) and started with the development of Visual MODFLOW. The company diversified into ...
MT3D is a family of finite-difference groundwater mass transport modeling software, often used with MODFLOW. The first generation, MT3D, was developed by Chunmiao Zheng in 1990, [1] [2] and most recently released by the U.S. Geological Survey with MT3D-USGS. [3]
