Modeling the Evolution of a Freshwater Lens under Highly Dynamic Conditions on a Currently Developing Barrier Island

Figure 4

Temporal evolution of the groundwater salinity distribution and FWL along cross-section A-A’ for the CG- (left column), VG- (central column), and CGWST-model (right column). Model results are presented for various simulation times, with the present situation after 42 years at the bottom row. The 1 g L^-1 (white line) and the 16 g L^-1 (i.e., 50% seawater, gray line) contour lines, respectively, are displayed for the present situation. Note that the salinities represent the distribution before storm tides occur at the end of each respective year.
