An unconfined aquifer is 100 feet thick was evaluated using a field pumping test. The depth to groundwater is 10 feet. At a distance of 1000 feet, the drawdown was 40 feet, and at a distance of 5000 feet it was 20 feet. Find the permeability of the aquifer assuming that a steady-state of 960 gal/minute during the test in ft/sec.

A site consists of a homogenous dense silty sand layerof 8m thickness which is underlain by an imprevious stiff clau stratum. The initial water table was at 3m depth below the ground level. A pumping test was carrier out by pumping water at the rate of 0.7 m^3/min. Onservation wells were dug into the ground at 25m and 50m distances from the center line of the well. At steady state (i.e., when there was no change in water levels in the observation wells), the water levels in the two wells dropped by 500mm and 150mm, respectively. Determine the hydraulic conductivity of the clay sand layer.
