Use of a three-dimensional model for the analysis of the ground-water flow system in Parker Valley, Arizona and California

Abstract

A three-dimensional, finite-difference model was used to simulate ground-water flow conditions in Parker Valley. The purpose of the study was to evaluate present knowledge and concepts of the groundwater system and the ability of the model to represent the system. Modeling assumptions and generalized physical parameters that were used may have transfer value in the construction and calibration of models of other basins along the lower Colorado River.
