Abstract : The U. S. Army Engineer Waterways Experiment Station (WES) and Brigham Young University (BYU) have jointly developed a user-friendly graphical interface for groundwater models, the Groundwater Modeling System (GMS). The GMS (BYU 1994a) is a pre- and post-processing software for several different groundwater models, including a three-dimensional finite element model of density-dependent flow and transport through saturated-unsaturated porous media (FEMWATER). The model was developed by G.T. (George) Yeh, Pennsylvania State University (PSU). The model stems from two previous codes, a groundwater flow model (3DFEMWATER) and a subsurface contaminant transport model (3DLEWASTE). The FEMWATER can handle all the options of the two previous models plus the option of density-driven flow and transport. The input and output structures of the model have been modified by WES to adapt the graphical interface file format. The documentation of FEMWATER user's manual has been published by WES (Lin and Yeh 1995). jg p.10
