A 30 cm well penetrates an unconfined aquifer of saturated depth of 25m. When a discharge of 2100 lpm was being pumped for a long time, observation wells at radial distances of 30m and 90m indicated drawdown of 5m and 4m, respectively. Estimate the coefficient of permeability and the drawdown at pumping well.

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.
