Groundwater Modeling System
The Department of Defense (DoD) Groundwater Modeling System (GMS) is a compre-
hensive software package that helps expedite environmental cleanups. This compre-
hensive graphical subsurface modeling environment incorporates a suite of numerical
modeling programs that allow civil engineers and others involved in hydrodynamic
modeling to visualize the contaminated sites, evaluate cleanup alternatives, and predict
their effectiveness. It provides tools for every phase of a groundwater simulation including
site characterization, model development, post-processing, calibration, and visualization.
GMS provides an integrated graphical environment for performing subsurface flow,
contaminant fate/transport, and efficacy and design of remediation systems evaluation
Because of a lack of knowledge in the past to the dangers associated with the handling and
disposal of certain chemical compounds, the U.S. Department of Defense has historically
generated subsurface environmental problems. Cleanup of these problems could take
decades with costs ranging into tens of billions of dollars.
