In an artesian aquifer of 8 m thick, a 10 cm diameter well is pumped at a constant rate of 100 lit/minute. The study state drawdown observed in two wells located at 10 m and 50 m distances from the center of the well are 3 m and 0.05 m respectively. (25 marks) a-Sketch the aquifer with wells b-Compute the transmissivity, e-What is the hydraulic conductivity of the aquifer. 3.
