FIG. 9.5.1 Combined confined and unconfined flow.

If one of the two constants Cu is set to zero, then

The potential $ can be expressed as

One-Dimensional Flow

Figure 9.5.2 shows combined confined and unconfined flow in an aquifer of thickness H and length L. The aquifer is confined at x = 0 and unconfined at x = L.

The expression for the potential $ is the same throughout the flow region as

However, the expression for $ in terms of ^ is different for each zone as given in Equation 9.5(4). The expression for the discharge Q is
