Application of Computational and Visualization Methods to Groundwater Modeling

Abstract

This report documents basic and applied research in the area of groundwater modeling. A three-dimensional finite element method program and model for the real-world problem of flow near Rocky Mountain Arsenal (RMA) is described, and a comparison with a two-dimensional finite element method RMA computation is done to help determine when a three-dimensional analysis is needed. Scientific visualization techniques and Cray Y-MP improvements developed in this RMA study are described. The finite volume method is applied to saturated/unsaturated flow and contaminant transport, and the results are compared to finite element method solutions. Nonlinear Newton iteration for unsaturated flow and the Lagrangian-Eulerian method for contaminant transport are discussed. Experimental results and analytical solutions are used to compare different procedures. Finally, contaminant transport results are viewed using scientific visualization tools.
