The computer model presented here utilizes a finite difference approximation of the groundwater flow continuity equation in an aquifer to predict water table elevations and the Todd (1980) equation to calculate velocity dependent capture zones for pumping wells. The model presented in this thesis has a series of wells, with variable pumping rates, advance through designated areas of a finite difference grid system discretizing the aquifer. Wells advance through the grid to new nodal configurations and an optimum well configuration solution is found when prescribed conditions are fulfilled. In a dewatering simulation, these conditions are in the form of predesignated control point potentiometric surface elevations that must be matched. In a plume management scenario, the conditions are fulfilled when a given capture well configuration maximizes the coverage of the contaminant plume. The model is able to simulate recharging ditches, collection ditches, induced infiltration from surface streams and ponds, as well as areas of no flow due to complex geology or foundation structures.
