Hydrogeology and Simulated Effects of Urban Development on Water Resources ofSpanish Springs Valley, Washoe County, West-Central Nevada

摘要

The purposes of this report are to describe and analyze the ground-water flowsystem in Spanish Springs Valley and to evaluate and refine estimates of the water budget and yield of the basin-fill aquifer. The ground-water budget and yield, estimated from field data and empirical techniques, were determined for 1994 hydrologic conditions. The report also discusses the results of a ground-water flow model used to simulate transient-flow conditions for a 16-year period (1979-94) and for several hypothetical development scenarios. The study includes Spanish Springs Valley and parts of the surrounding mountainous area. Hydrologic data, including water levels, ground-water withdrawals, precipitations, surface-water discharge, and water-chemistry analyses, were considered in this study.
