Modeling 3-D Ground Water Mounding

Groundwater mounding is caused by localized recharge to the saturated zone in an unconfined aquifer. Estimation of groundwater mounding shape and height is important to provide an estimate of the unsaturated thickness between the mound and recharge source and to predict mixing and distribution of recharged substances in the aquifer. The paper presents a three-dimensional model for calculating mounding using generalized coordinates and finite differences.
