A permeability pumping test was carried out in a confined aquifer with the piezometric level before pumping is 2.18 m. below the ground surface. The aquiclude (impermeable layer) has a thickness of 5.7 m. measured from the ground surface and the confined aquifer is 7.6 m. deep until it reaches the aquiclude (impermeable layer) at the bottom. At a steady pumping rate of 15.6 m³/hour the drawdown in the observation wells were respectively equal to 1.62 m. and 0.47 m. The distances of the observation wells from the center of the test well were 15 m. and 32 m. respectively.
? Compute the depth of water at the farthest observation well. (m)
? Compute the coefficient of permeability. (m/s)
? Compute the transmissibility of the impermeable layer. (m²/s)
