Groundwater is depleted as it is pumped out from wells for drinking. It is replenished by the process of infiltration. An 800-acre area that receives 52 in./y of precipitation is developed from wild grassland with a runoff coefficient of 0.18 into a subdivision with: Runoff coefficient Area Type 300ac Grassy land 0.20 200 ac Pavement 0.75 300 ac Residentia 0.40 With the loss of vegetation, evapotranspiration is reduced from 24 in./y to 18 cm/y. As a result of the development, what is the change in the annual volume of rainwater (in gallons) that infiltrates to become groundwater? Assume no annual change in storage.
