Evaluation of a Ground-Water Flow and Transport Model of the Upper Coachella Valley, California

摘要

The report describes an evaluation of the existing ground-water simulation model of the upper Coachella Valley developed by Swain (1978). The evaluation consisted of several steps. First, an updated geohydrologic data base was compiled to evaluate changes in ground-water conditions since publication of the results of Swain's study. Second, the compiled data were analyzed to characterize the ground-water flow system and to quantify the effects on water quality of the artificial-recharge program during 1979-86. Third, the existing model was used to simulate ground-water flow and solute transport for the period 1979-86. The results of these simulations helped identify future modeling and data-collection needs for the valley.
