A well is to be installed in an unconfined sandy aquifer to lower the water table for a large construction project. The steady-state drawdown must be at least 1.5 m within a distance of 30 m from the well and 3.0 m within a distance of 3.0 m from the well. The hydraulic conductivity of the sand is 1.00 × l0-4 rn/sec. A relatively impermeable clay with a hyd raulic conductivity 100 × 10-10 m/sec forms the base of the aquifer. The depth of the water in the aquifer above the clay layer before pumping is 8.2 m. Calculate the required discharge from the well to meet the design conditions. Assume a radius of influence of 150 m.
