A confined aquifer has a thickness of 30m (m) and is fully penetrated by well where the aquifer is pumped at the rate of 500 litres per second. The groundwater thickness (H₁) is 50 m. The drawdown measured in two observation wells located at distance of 10 m and 100 m from the well are 7.5 m and 0.5m respectively. Determine the average hydraulic conductivity of the aquifer. At what distance from the well the drawdown is insignificant i.e. is zero (R

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.
