Use this Theis method equation to characterize the behavior of a confined aquifer that is homogeneous and isotropic with T = 500 m2/day and S = 1 ( 10-5. A single well is pumped at 2500 m3/day.
a) Compute the draw down 75 m away from the well at t = 1, 10, 100, 1000, and 10,000 minutes after pumping began.
b) Compute the draw down after 1.0 day of pumping at locations r = 2, 5, 10, 50, 200, and 1000 m from the pumping well?
