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 ...
Two-dimensional model of subsurface drainage in a vertical plane Three-dimensional grid, Modflow One-dimensional models can be used for the vertical flow in a system of parallel horizontal layers. Two-dimensional models apply to a vertical plane while it is assumed that the groundwater conditions repeat themselves in other parallel vertical ...
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.

The original version of Visual MODFLOW, developed for DOS by Nilson Guiguer, Thomas Franz and Bob Cleary, was released in August 1994. It was based on the USGS MODFLOW-88 and MODPATH code, and resembled the FLOWPATH program developed by Waterloo Hydrogeologic Inc. [clarification needed] The first Windows based version was released in 1997. [1]
US Geological Survey water resources homepage — a good place to find free data (for both US surface water and groundwater) and free groundwater modeling software like MODFLOW. US Geological Survey TWRI index — a series of instructional manuals covering common procedures in hydrogeology. They are freely available online as PDF files.
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.
It has been developed to support converting a LeapFrog model to unstructured and structured grids and exporting to a GUI ready NAM file, however doe not have the functionality of running MODFLOW. 203.211.75.213 ( talk ) 04:12, 13 September 2024 (UTC) [ reply ]
