operating systems.
Benefits/Savings
GMS integrates and simplifies the process of groundwater flow and transport modeling by
bringing together all of the tools needed to complete a successful study. GMS provides a
comprehensive graphical environment for numerical modeling and tools for site charac-
terization, model conceptualization, mesh and grid generation, geostatistics, graphical
visualization, and remedial alternative evaluation. Using GMS can save time and money,
as much as 20 percent on overall project remediation costs.
