Two monitoring wells are drilled into an aquifer 240 ft apart. The aquifer is sand with K = 12 ft/d, porosity = 0.23, and a thickness of 45 ft. Using the data below, determine the hydraulic gradient, Darcy velocity, and seepage velocity between the two wells. What direction is water flowing?

        well 1               well 2

casing elevation (ft MSL)        142.34             157.61

depth to water (ft)                  18.04               29.78

In an aquifer two wells are located 1400 m apart with a difference in head of 22 m. The cross sectional area of the aquifer is 30 m thick and 120 m wide with a hydraulic conductivity of 7 m/day. The average linear velocity between the wells is 0.5 m/day. Find the volume of the groundwater flowing across the cross-sectional area in m3/day and the porosity. (Hint: Use Darcy's Law)

Two wells are drilled 50 m apart in an aquifer which has K = 0.05 cm /s. The original height of the phreatic surface above the aquiclude is 12.2 m. The wells are pumped at a rate of 10 L/s. It is estimated that the effect of the pumping extends a distance of 600 m from the center of the well group. Determine the shape of the drawdown curve. The well diameters are 0.5 m.

1. Write at least two sentences in your own words to explain the difference between the hydraulic conductivity and transmissibility for a given confined aquifer. 2. Answer True or False and justify your answer:     a. The flow per unit width at a homogeneous unconfined aquifer is inversely proportional to its hydraulic conductivity.     b. For a confined aquifer with 40% porosity and thickness of 50 ft the seepage velocity is higher than its Darcy velocity = Specific Discharge =...
