Concept explainers

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

(b) A valley with an unconfined aquifer system has an area of 1000 ha, the specific yield
of the aquifer material is 0.20. Estimate how much water will be released from
