Q-3 (20 points) Using the Jacob method: A pumping test was conducted in a 40-m-thick confined aquifer. Drawdown data plotted in figure 2 below were collected in an observation well 20 m away. The test well was pumped at the constant rate of 8.50 m²/hr. Determine the aquifer transmissivity, the storage coefficient, and the drawdown after a year if pumping continues. 3.0 Pumping test data 25 20 . 0.90 m Drawdown, he-h (m) 1.5 - 0 os 1-1.72 x 10-br. 0 10 10 102 10-1 Time since pumping began, (hr) Figure 2
