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

Figure 3

Model set-up of the north-south oriented cross-section A-A’ (Figure 1) with initial and boundary conditions. Fresh recharge areas indicate variations of the position and extent of the elevated dune area for the depicted years considered in the VG-model. Between these years, the recharge salinity of the previous year was assigned. In the CG- and CGWST-model, the salinity distribution of 2014 was kept constant. Salinities are indicated by the color scale (this also applies to the following figures). Zones A-F represent zones of different recharge rates kept constant in the CG- and CGWST-model. In the VG-model, zones depended on the geomorphology of the respective year.
