A 40-cm-diameter well draws water from a confined aquifer at the rate of 1.33 m3/s. The aquifer is 30.5 m thick with a piezometric surface (prior to pumping) that is 107 m above the bottom of the confined aquifer. The drawdown at an observation well 50 m away is 10.1 m. If the same well is placed in the same aquifer, 400 m from a completely penetrating stream, determine the drawdown at the well and at the boundary. The aquifer permeability is 4.35 * 1 m/s.
