GMS 8.0 Now Available!

GMS is the most sophisticated and comprehensive groundwater modeling software available!

GMS is the most sophisticated and comprehensive groundwater modeling software available! Used by thousands of people at U.S. Government agencies, private firms, and international sites in over 90 countries, it has been proven to be an effective and exciting modeling system. GMS provides tools for every phase of a groundwater simulation including site characterization, model development, calibration, post-processing, and visualization. GMS supports both finite-difference and finite-element models in 2D and 3D including MODFLOW 2000, MODPATH, MT3DMS/RT3D, SEAM3D, FEMWATER, PEST, UTEXAS, MODAEM and SEEP2D. Regardless of your modeling needs, GMS has the tools!

The program's modular design enables the user to select modules in custom combinations, allowing the user to choose only those groundwater modeling capabilities that are required. Additional GMS modules can be purchased and added at any time. The software will dynamically link to these subsequent modules at run time - automatically adding additional modeling capability to the software.
