4.3 Numerical example 3
For this example, two cases with different initial hydraulic heads are considered. Figure 8 illustrates the schematic of finite confined coastal aquifers. In Case A, the initial groundwater level is considered to be constant, , as shown in Figure 8 (a). In Case B, we consider the initial head to be , where denotes the head of the sea side, adenotes the gradient of the hydraulic head in the sea side, and denotes the averaged mean sea level. As shown in Figure 8 (b), the groundwater head may linearly increase as the distance from coastline increases.
