GMS (Groundwater Modeling System) is a complete program for building and simulating groundwater models. It features 2D and 3D geostatistics, stratigraphic modeling and a unique conceptual model approach. Currently supported models include MODFLOW, MODPATH, MT3DMS, RT3D, FEMWATER, SEEP2D, and UTEXAS.
Version 6 introduced the use of XMDF (eXtensible Model Data Format), which is a compatible extension of HDF5. The purpose of this is to allow internal storage and management of data in a single HDF file, rather than using many flat files.
GMS was initially developed by the Engineering Computer Graphics Laboratory at Brigham Young University (later renamed in September, 1998 to Environmental Modeling Research Laboratory or EMRL) in the late 1980s on Unix workstations. The development of GMS was funded primarily by The United States Army Corps of Engineers and is still known as the Department of Defense Groundwater Modeling System or DoD GMS. It was later ported to Microsoft Windows platforms in the mid 1990s. Version 3.1 was the last supported version for HP-UX, IRIX, DEC-OSF, and Solaris platforms.
In April 2007, the main software development team at EMRL entered private enterprise as Aquaveo, LLC, and continue to develop GMS and other software products, such as WMS (Watershed Modeling System) and SMS (Surface-water Modeling System).
