The U.S. Army Engineer Waterways Experiment Station Groundwater Modeling Team performed a broad review of available groundwater models and an assessment of Army modeling. The first step was a model screening based primarily on current and anticipated Army and Department of Defense needs, followed by a more rigorous evaluation. This report provides the initial evaluation of more than 12 groundwater models that were selected based on the screening criteria. The effort included scrutiny of the code structure, certain process formulation, and performance evaluation relative to appropriate problems for which analytical solutions are available andor hypothetical scenarios. Four classes of models were evaluated 1 saturated flow andor transport, 2 coupled unsaturatesaturated flow andor transport, 3 unsaturated flow andor transport, and 4 multiphase models. Model performance in the initial evaluation was acceptable for the suite of models. The second step was to evaluatecompare the models against analytic solutions, hypothetical scenarios, andor filed data.
