Question 3: (Unsteady - Leaky confined - parameters by Walton curves) The following data were recorded in as pumping test on a well confined by a semi-pervious stratum of 4.2 m thickness. The well is pumped at a rate of 0.12 m/min and the drawdown is measured in the observation well 100 m away. Determine the aquifer characteristics. Time (min) 5 15 30 45 60 90 120 240 Drawdown (m) 0.08 0.30 0.55 0.68 0.74 0.80 0.84 0.88
