Dependency of (a) seawater inflow and (b) (the elevation of the deepest point where ³H> 0.02 TU) on vertical hydraulic conductivity for simulation A3 with different anisotropy ratios. The corresponding anisotropy ratios are displayed along the top horizontal axis of the graph. was calculated by summing the inflow across the specified head cells along the seafloor. The vertical error bars represent one standard deviation of the temporal variability of and , which is caused by the transient recharge (Figure 2(c)).
