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.
This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality. Notice that 'free and open-source' requires that the source code is available and users are given a free software license.
An unambiguous definition of "groundwater model" is difficult to give, but there are many common characteristics. A groundwater model may be a scale model or an electric model of a groundwater situation or aquifer. Groundwater models are used to represent the natural groundwater flow in the environment.
In 1997, WMS was used by the COE to model runoff in the Sava River basin in Bosnia. [13] The software was sold commercially by Environmental Modeling Systems. [14] It was later ported to Windows platforms in the mid 1990s. WMS 6.0 (2000) [14] was the last supported version for HP-UX, IRIX, OSF/1, and Solaris platforms.
The source code is free public domain software, [1] written primarily in Fortran, and can compile and run on Microsoft Windows or Unix-like operating systems. 3-dimensional grid. Since its original development in the early 1980s, [2] the USGS has made six major releases, and is now considered to be the de facto standard code for aquifer simulation.
Integrated Water Flow Model (IWFM) [1] [2] is a computer program for simulating water flow through the integrated land surface, surface water and groundwater flow systems. It is a rewrite of the abandoned software IGSM, which was found to have several programing errors. [2] The IWFM programs and source code are freely available.

HydroGeoSphere (HGS) is a 3D control-volume finite element groundwater model, and is based on a rigorous conceptualization of the hydrologic system consisting of surface and subsurface flow regimes. [ 1 ] [ 2 ] The model is designed to take into account all key components of the hydrologic cycle .
