**5. Bay responses to sea level rise**

The 1978 and 2007 events were simulated repeatedly under varying sea level rise scenarios. In each run, the open boundary and initial sea surface heights were increased in 1-foot increments from the baseline scenario to a 7-foot scenario to emulate potential water levels. Utilizing the wetting and drying module of FVCOM, mesh cells in Saco Bay and Casco Bay were classified as either "dry," "intertidal," or "wet." The former (latter) were defined as cells in the mesh, which never became wet (dry) throughout the model's runtime. Intertidal areas were cells that alternated between wet and dry.
