3.a
The specific storage of a confined aquifer is 5x10³ m. If the aquifer is 50 m thick, how much
water (m²) would the aquifer produce if the piezometric surface is lowered by 50 m over an area of 50 km²?
b. A confined aquifer has a source of recharge as shown in Figure below. The hydraulic conductivity
of the aquifer is 100 m/d and its porosity is 0.35. The piezometric head in two wells 1000 m apart is 75 m
and 70 m, respectively, from the common datum. The average thickness of the aquifer is 50 m and the
average width is 5 km. Determine the rate of flow (m³/d) through the aquifer.
