Question

3.In a water table aquifer bounded on the ends by rivers, the hydraulic conductivity is 50 m/day. The hydraulic heads at x = 0 and x = 1000 m are 100 m and 90 m, respectively.

(a) Calculate the darcy flux at x = 0, 100, 500 and 1000 m, and the flow rate per uit width of the aquifer. Assume recharge = 0

(b) Calculate the darcy flux at x = 0, 100, 500 and 1000 m, and the flow rate per unit width of the aquifer. Assume recharge = 0.02 m/day

(c) For (b), given the streams are located at x = 0 and x = 1000 m, determine where the groundwater divide is located.

Explanation / Answer

PV = nRT Solve for n n = PV/RT n = (0.854)(120)/0.082057)(388K) = 3.22 moles ........ 3.22 x 44.1 g/mole = 142 g ........
