2. A building site in sand has a high ground water table, which must be temporarily ered during construction. Four wells will be constructed. The coordinates of the wells in feet are: W1(100,100); W2(300,100); W3(300,300); W4(100,300). An observation piezometer will be constructed at P1(200,200). The drawdown at the piezometer must be greater than or equal to 10 feet. The radius of influence low is 800 feet. The hydraulic conductivity of the unconfined aquifer is 50 fuld. Before pumping, the saturated thickness of the unconfined aquifer is 80 feet. Determine the minimum flow rate to achieve the required drawdown. Submit Lingo inout file
