A well is constructed to pump water from a confined aquifer. Two observation wells, MW1 and MW2, are constructed at distances of 100 m and 1000 m, respectively. Water is pumped from the pumping well at a rate of 0.2 m3  /min. At steady state, drawdown s is observed as 2 m in MW2 and 8 m in MW1. Note that drawdown is greater (8 m) for well MW1 located closest to the pumping well. Determine the hydraulic conductivity K and transmissivity T if the aquifer is 20 m thick

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.
