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

The discharge from a fully penetrating well operating under steady state in a confined
aquifer of 35 m thickness is 2000 1pm. Values of drawdown at two observation wells 12
and 120 m away from the well are 3.0 and 0.30 m respectively. Determine the permeability of
the aquifer.
