Unidirectional Flow

Unidirectional flow considered here is steady, one dimensional and horizontal between two water bodies. Although groundwater motion occurs with very small velocities, the large cross  sectional area through which this motion takes place results in large quantities of water flow. Three cases are examined here.

Flow through a Confined Aquifer Consider flow through a confined aquifer as shown in Figure (3.6a). The confined aquifer connects a natural water body such as a river or lake to a trench through which water is pumped at a constant rate of  The trench has been excavated parallel to the water body.
