Subsurface Contaminant Transport / Fate Models

A variety of models are being developed and applied for subsurface contaminant transport and fate, with an emphasis on site investigation and remediation. Most of these models are three-dimensional and are being incorporated into the DoD Groundwater Modeling System (GMS). The GMS provides the user with a graphical interface to facilitate model conceptualization, setup, and postprocessing analyses. The GMS presently hosts FEMWATER, MODFLOW, and MT3D, and other models are being added. GMS capabilities will eventually extend to the full suite of subsurface modeling needs, including multiphase flow and transport. A variety of remediation simulation capabilities have been targeted for GMS fielding, such as bioremediation, reaction walls, soil vapor extraction, and others.
