Groundwater table contours

Looking for help with the following questions.


Solution Preview

a. See the attached file. Groundwater moves from the higher elevation areas to the lower ones. The straight lines are perpendicular to the contours and indicates is the shortest distance between the contours.

b. The hydraulic gradient is the change is height divided by the distance: 2/10 = .4

c. Given Darcy's Law, Q = KA h1-h2/L where L is the distance, we can divide through by area to find the specific discharge:
q = K ...
