An unconfined aquifer has a hydraulic conductivity of 1.2×10² cm/s. There are two fully penetrating observation wells installed in this aquifer, which are separated by a distance of 98.5 m from each other. In the upstream observation well, the water level is 7.5 m above the aquifer bottom, and in the downstream observation well, it is 6.0 m above the aquifer bottom. (i) What is the groundwater discharge per 40 m-wide strip of the aquifer? Express your answer in cubic meters per day. (ii) What is the water-table elevation at a point midway between the two observation wells?

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.
