“…We supplemented the inlet data set with additional inlets for which long-term migration rates were available, such as Chatham Inlet, MA [Giese, 1988], Katama Inlet, MA, (Figure 1) and New Inlet, NC [Hasbrouck, 2007]. See supporting information Table S3 for an overview of the natural tidal inlet estimated properties [Komar, 1971;Everts et al, 1974;DeAlteris et al, 1976;Mason, 1981;Aubrey and Speer, 1984;Inman and Dolan, 1989;Stone et al, 1992;Kennish, 2001;Cleary and FitzGerald, 2003;State of Florida, 2009;Stive et al, 2010;Mallinson et al, 2010;Nienhuis et al, 2015].…”

Tidal inlets on barrier coasts can migrate alongshore hundreds of meters per year, often presenting great management and engineering challenges. Here we perform model experiments with migrating tidal inlets in Delft3D‐SWAN to investigate the mechanics and rates of inlet migration. Model experiments with obliquely approaching waves suggest that tidal inlet migration occurs due to three mechanisms: (1) littoral sediment deposition along the updrift inlet bank, (2) wave‐driven sediment transport preferentially eroding the downdrift bank of the inlet, and (3) flood‐tide‐driven flow preferentially cutting along the downdrift inlet bank because it is less obstructed by flood‐tidal delta deposits. To quantify tidal inlet migration, we propose and apply a simple mass balance framework of sediment fluxes around inlets that includes alongshore sediment bypassing and flood‐tidal delta deposition. In model experiments, both updrift littoral sediment and the eroded downdrift inlet bank are sediment sources to the growing updrift barrier and the flood‐tidal delta, such that tidal inlets can be net sink of up to 150% of the littoral sediment flux. Our mass balance framework demonstrates how, with flood‐tidal deltas acting as a littoral sediment sink, migrating tidal inlets can drive erosion of the downdrift barrier beach. Parameterizing model experiments, we propose a predictive model of tidal inlet migration rates based upon the relative momentum flux of the inlet jet and the alongshore radiation stress; we then compare these predicted migration rates to 22 natural tidal inlets along the U.S. East Coast and find good agreement.

“…Coastal dunes with heights up to 4.6 m exist on the northern portion of the island. Average shoreline change was approximately -2.5 m/year during the study period (Everts, DeWall, and Czerniak 1980). A seawall and groin field is located in the central part of the island.…”

Volume change above msl by 0.5-m contour slices (negative, erosion) e^.Total volume change above msl (negative, erosion).Note that volume quantities are actually computed cross-sectional areas multiplied by a unit length of beach (1 m) . Foreshore slopes, shoreline positions, and volume changes were computed using the Beach Profile Analysis System (Fleming and DeWall 1982).If required, the position of the shoreline (msl intercept) was extrapolated using the last two survey points but only if the last surveyed point was below an elevation of 0.6 ra. The total volume change above msl was computed only if a msl intercept was computed. Volume change computations were terminated at a maximum elevation of 18 m, a fact that nominally affects a few profile lines on Nauset Beach.
