9. A single well pumps water from a horizontally infinite confined aquifer at a rate of 2.1 m³/day. The well-bore diameter is 15 cm, and steady-state drawdown at the pumping well is 1.1 m. Drawdown at a monitoring well located 97 m away is measured at 0.14 m. a) Estimate the Transmissivity (T) of the aquifer. b) Based on that estimate, what would you expect the drawdown to be 54 m from the pumping well? c) How would you estimate the Hydraulic Conductivity (K) from the information you have? What other information would you need?
