ABSTRACT

A pumping test is conducted with Q = 200 gal/min. The saturated thickness of the aquifer is 20 feet. The radius of the pumping well is 4 inches. At equilibrium, the drawdown in the pumping well is 8 feet, and the drawdown in an observation well 100 feet from the pumping well is 2 feet. If the initial piezometric head is 50 feet, determine the aquifer transmissivity.
