HYDROLOGIC IMPLICATIONS OF GREATER GROUND-WATER RECHARGE TO LAS VEGAS VALLEY, NEVADA

摘要

Published estimates of natural recharge in Las Vegas Valley range between 21, 000 and 35, 000 acre-feet per year. This Study examined the underlying assumptions of previous investiga- tions and evaluated the altitude-precipitation relationships. Period- Of-record averages from high altitude precipitation gages Established in the 1940s through the 1990s, were used to determine Strong local altitude-precipitation relationships that indicate new Total precipitation and natural recharge amounts and a new spatial Distribution of that recharge.
