Exercise 8

Part 1: Two wells are completed in two different confined aquifers. All things are equal (e.g., same saturated thickness, storage parameters, well diameter, screened intervals, well efficiency, and so on) except that the transmissivity of aquifer A is 1.2 times greater than the transmissivity in aquifer B (i.e., [latex]T_{a} = 1.2T_{b}[/latex]). If each well is pumped at the same rate for the same amount of time, which well will experience the greater drawdowns? Circle one of the answers:

Part 2: The following graph shows aquifer test results—specifically, time‑drawdown data from observation wells—from two different aquifer tests in two different confined aquifers. For each test, the pump rate is the same and the distance to the observation well from the pumping well is the same. Assume that each aquifer has the same storativity.

Which aquifer has the greater transmissivity? Circle one:
