********GMS 6.0********* --------------------------- Groundwater Modeling System (GMS) 6.0 --------------------------------------- GMS (Groundwater Modeling System) is a comprehensive software package for developing computer simulations of groundwater problems (flow and contaminant transport). GMS provides tools for site characterization, model development, post-processing, calibration, and visualization. It supports TINs, solids, borehole data, 2D and 3D geostatistics, and both finite element and finite difference models in 2D and 3D, including MODFLOW, MODPATH, MT3D, RT3D, FEMWATER, SEEP2D, ART3D, MODAEM, SEAM3D, and UTCHEM. Parameter estimation is supported through the processes included with MODFLOW-2000, PEST, and UCODE. GMS’s design, allows the user to select “modules” in custom combinations. These modules are related to pre- and post-processing, model selection, and calibration routines. Discussion of all modules is beyond the scope of this review, but many commercial vendors have websites with detailed descriptions of each module and how they can be used (search on GMS 6.0). New users can select specific modules for a current project and add modules as needs expand or change. Use of GMS saves time by having a modeling “package” that is the same for a variety of programs. The initial learning curve is steep. However, GMS uses the same “conceptual model” approach (discussed below) for alternative modeling programs (e.g., MODFLOW and FEMWATER). GMS is 8-user license software. The faculty-in-charge:Prof A K Rastogi Contact sys admin or mail to help@civil.iitb.ac.in For more details:: http://typhoon.mines.edu/software/igwmcsoft/GMS_Review.html
