The figure is a plan view of a confined aquifer showing two contaminated zones, 1 and 2. The aquifer has a saturated thickness of 80 ft, hydraulic conductivity of 42 ft/d, and the regional hydraulic gradient is 0.0075 from right to left as shown. A pumping well with a flow rate of 170 gpm is planned to run continuously at the location shown, and form a stable (equilibrium) capture zone. You may assume that the 2500 ft distance from the well to zone 1 is long enough that the capture zone has reached its maximum width. 2 200 ft Determine: pumping well 2500 ft 700 ft regional flow direction 1.

A 927-acre catchment has been monitored for many years. It has been found that the average annual rainfall over the catchment is 37 inch and that the average streamflow is 1.0 cfs. Geologic investigations reveal a bedrock underlying the catchment that effectively prevents any deep seepage or groundwater recharge. Estimate the average annual evapotranspiration in inches for this catchment.
