摘要

This paper summarizes and highlights results from articles that describe the construction, verification, calibration, validation, and demonstration of two groundwater flow and contaminant transport models: A Finite Element Model of Water Flow through Aquifers (FEWA) and A Finite Element Model of Material Transport through Aquifers (FEMA). The construction is based on the finite element approximation of partial differential equations of groundwater flow for FEWA and solute transport for FEMA. The particular features of FEWA and FEMA are their versatility and flexibility for dealing with vertically integrated two-dimensional problems. The models were verified against both analytical solutions and widely used US Geological Survey finite difference approximations. They were then applied, for calibration and validation, to five field sites across the United States. Results indicated that the models yielded good agreements with the field data for all five sites. Finally, to demonstrate the versatility and flexibility of the models, they were used to simulate two hypothetical, but realistic, complex problems. Model predictions for these two examples were consistent with and comparable to the qualitative analysis of the hydrologic setting. (ERA citation 12:029318)
