A confined aquifer 12.0m thick has a piezometric surface 25.0 m above the bottom confining layer. Groundwater is being extracted from a 0.2 m diameter fully penetrating well. The pumping rate is 0.150 m3/min. The aquifer is relatively sandy and has a hydraulic conductivity of 230 m/d. Steady-state drawdown of 1.8 m is observed in a monitoring well 4.0 m from the pumping well. Calculate: i. The drawdown in the pumping well ii. The radius of influence of the 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.
