GMS includes a comprehensive graphical interface to the groundwater model MODFLOW. MODFLOW (originally called the Modular Three-Dimensional Finite-Difference Ground-Water Flow Model) is a 3D, cell-centered, finite difference, saturated flow model developed by the United States Geological Survey (McDonald & Harbaugh, 1988). MODFLOW can perform both steady state and transient analyses and has a wide variety of boundary conditions and input options. In GMS, MODFLOW can work with the 3D Grid module and 3D UGrid module.
GMS supports MODFLOW as a pre- and post-processor. The input data for MODFLOW are generated by GMS and saved to a set of files. These files are read by MODFLOW when MODFLOW is launched from the MODFLOW menu. The output from MODFLOW is then imported to GMS for post-processing.
A special version of MODFLOW is distributed with GMS. This version of MODFLOW is the same as the version distributed by the USGS except for a few minor changes primarily related to file input including reading input data from HDF5 files. These changes are clearly marked in the code. For more information see MODFLOW with HDF5.
To learn more about using MODFLOW in GMS, please refer to the available tutorials.
More information about MODFLOW is available from the USGS.
The MOFLOW model is included with all editions of GMS, including the community version.
GMS supports all standard MODFLOW versions. For a list of input files and packages supported in each version see here.
