Question

1. Drawdown at a 0.20 m diameter, fully-penetrating well, which has been pumping at a steady rate of 2500 m³/day for a long time, is determined to be 1.2 m. Drawdown at an observation well 10 m away is 0.90 m.

a. The aquifer is unconfined with a hydraulic head far from the well of 10.0 m. Determine the hydraulic conductivity of the aquifer.

b. How would your answer change if your aquifer was confined and 3 m in thickness? Assume that the hydraulic head data from    (a) remains true.

c. Would a wetland 250 m away from the well be affected? Assume that a drawdown at the wetland of more than 0.10 m is    unacceptable.

There are other problems up that are similar but nothing extremely close. I'm quite confused. Thank you for the help.
