Question

Question 3

A 20 m thick aquifer has a hydraulic conductivity of 10-3 cm/s and a specific

storage of 1x10-5 m-1. A pump test is conducted where the well pumping rate is 1000 m3/day for a period of 24 hours. Then the well is turned off.

a). Determine the drawdown after 48 hours at an observation well that is 100 m from the pumping well if the aquifer is fully confined (5 marks). 


b). Determined the drawdown after 48 hours at an observation well that is 100 m from the pumping well if the aquifer is bounded above by a 10 m leaky aquitard that has a hydraulic conductivity of 10-6 cm/s, neglecting storage in the aquitard (5 marks).
