14. A 40-cm-diameter well draws water from a confined aquifer at the rate of 1.33 m³/sec. 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. The aquifer permeability is 4.35 x 10 m/sec.

Groundwater Flow

The term groundwater refers to the water which is found beneath the earth's surface. Pores present in the soil and rocks with fractures make a passage for rainwater to enter the earth's surface and deposit as groundwater. The flow nature and direction of groundwater under the earth's surface directly impacts the strength and compressibility of the soil, which reflects its ability to support structural loads.
