well in an aquifer is pumped over a long period at a rate of 0.05 m3 /s under approximate steady-state conditions. The steady-state drawdowns, from the water table level, at two observation wells at 25 m and 50 m from the abstraction well were observed to be 15.3m and 9.5m, respectively. If the saturated thickness of the aquifer prior to pumping is 80 m, determine the hydraulic conductivity of the aquifer material.

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.
