A confined aquifer receives water from a lake (recharge zone) and discharge into a river adjacent located 6 miles from Lake. The elevation level (Head) in the lake is 200 ft msl and 100 ft river msl. A well located 2 miles downstream from the lake with an elevation of 230 ft msl and water depth of 60 ft.
A geological fault truncates the aquifer at a distance "L" upstream from the river. The hydraulic conductivity of the area between the fault and the river is 50 ft / day and hydraulic conductivity between the lake and the fault is 100 ft / day. Since the thickness of the aquifer is 50 ft, calculate:

a-The flow rate from the lake and into the aquifer.

b-distance corresponding to the length L of low conductivity of the aquifer.

c-potentiometric load at a distance L.

d-trip time from the lake to the river, assuming a porosity of 30%.
