(10 Points) A contractor is trying to estimate the distance to be expected of a drawdown

of 4.81 m from a pumping well under the following conditions:

Pumping rate = 0.0280 cubic meter per seconds

Pumping time = 1066 d

Drawdown in observation well = 9.52 m

Observation well is located 10.00 m from the pumping well

Aquifer material = medium sand

Aquifer thickness = 14.05 m

Assume that the well is fully penetrating in an unconfined aquifer.
