##### Reference no: EM13296688

The Salt River Valley in central Arizona is an alluvial valley with an unconfined aquifer system that is heavily pumped but received little replenishment. The area is about 100,000 ha, the ground water pumping about 500 million m3 per year, and the water table drop about 3 m per year. Assuming no replenishment, what is the specific yield of the aquifer material?
