GMS includes a graphical interface to the groundwater model FEMWATER. FEMWATER is a 3D finite element, saturated/unsaturated, density driven, flow and transport model.

GMS includes a graphical interface to the FEMWATER (Finite Element Model of Water Flow Through Saturated-Unsaturated Media) model. FEMWATER is a 3D finite element, saturated/unsaturated, density driven, flow and transport model. FEMWATER was originally written by G.T. (George) Yeh at Penn State University (Yeh, et. al., 1992). The version of FEMWATER that is supported by GMS has been modified by G.T. Yeh and Dr. Hsin-Chi (Jerry) Lin of the U.S. Army Engineer Waterways Experiment Station (WES). This version is a coupled version of the original FEMWATER model (which solved for flow only) with the transport model LEWASTE (also developed by George Yeh).

A separate reference manual is available which describes the new version of FEMWATER in detail (Lin, et. al., 1997). This manual contains a description of the input requirements and should be read completely before using GMS to set up a problem.

GMS provides a custom interface to the FEMWATER model offering a simple way to set model parameters and a graphical user interface to run the model then visualize the results. FEMWATER allows modeling of salinity intrusion and other density-dependent contaminants. Complex stratigraphy can be developed in GMS and directly represented in the model. Solutions can be displayed using realistic 3D plots and animation sequences.

The FEMWATER model can be added to a paid edition of GMS.
