Combined Confined And Unconfined Flow

As water flows through a confined aquifer, the flow changes from confined to unconfined when the piezomet-ric head ^ becomes less than the aquifer thickness H. This case is shown in Figure 9.5.1. At the interzonal boundary, the head ^ becomes equal to the thickness H. The continuity of flow requires no change in discharge at the interzonal boundary. Hence, the following equation governing the discharge potential is the same throughout the flow region:


At the interzonal boundary, $ yields the same value, giving
