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.

Question

An aquifer is spread over 300 Ha. The water table in the aquifer was 6 m below the ground surface. A
drawdown of 3 m was observed after sometime. Find the change in the ground water storage if the
