Q1. Consider a confined aquifer which has a piezometric surface of 31 m and 11 m thickness. The diameter of the pumping well is 0.2 m, and the pumping rate is 1.200 m3/d. The hydraulic conductivity is 4.48 m/d. A steady-state drawdown of 1.0 m is observed at a monitoring well located 4.0 m away from the pumping well. a) Use Figure Q1 and label the given data appropriately and clearly including the units. (7 marks) b) Calculate the drawdown in the pumping well. (3 marks) c) Calculate the radius of influence of the pumping well (a distance at which the drawdown stops changing). (4 marks)
