Problem #7 (problem 3.4.3 page 141) A confined aquifer has a constant thickness of 34 m and is stratified between two observation wells as shown in the following figure. Given the piezometric surface elevations on the figure, determine the flow per unit width of the aquifer. What is the equivalent hydraulic conductivity in the direction of the flow/ for the portion of the aquifer between the two observation wells? L₁ = 15 m, L2 25 m, L3 = 15 m K₁ = 20 m/d, K2 = 10 m/d, K3 = 15 m/d +14.6 m +2.8 m KA KB KC
