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

A confined aquifer has a transmissivity T = 200 ft2/day (18.6 m²/day) and a storativity S = 0.0002. A fully penetrating well begins pumping in this aquifer at a rate of 1500ft³/day (42.5m³/day).

Using the Theis solution predict the drawdown h₀ h at a radius of r = 100 ft (30.5 m) at the following elapsed times: 10 minutes, 1 hour, 5 hours, and 24 hours.

The thickness of a horizontal, confined, homogeneous, isotropic aquifer of infinite areal extent is 30m. A well fully penetrating the aquifer was continuously pumped at a constant rate of 0.1 m³/s for a period of 1 day. The drawdowns given in the table below were observed in a fully penetrating well 90 m from the pumping well. Compute the transmissivity and the storativity by using: a) the Theis method of log-log matching. b) the Cooper-Jacob method of semi-log plotting.
