Idealized cross-shore XBeach simulations of storm-induced barrier island change with varying subaerial profile and sediment mobility characteristics

Six thousand, four hundred and fourty four (6,444) two-dimensional, cross-shore computational simulations were carried out with the open computational model XBeach (Roelvink et al., 2009, Coastal Engineering; https://oss.deltares.nl/web/xbeach/) to investigate the influence of subaerial barrier-island profile shape and sediment mobility on barrier-island morphological response during coastal storms; results are presented in Irish et al. (2024; DOI: 10.1061/JWPED5/WWENG-2047). All simulations were forced at the offshore boundary (25-m depth) with (1) a 6-hr sinusoid storm surge timeseries varying from 1 m, Mean Sea Level (MSL) up to the provided Peak Surge value then returning to 1 m and (2) JONSWAP wave spectra with significant wave height and peak period respectively of 8 m and 10 s. Initial barrier island profiles, final XBeach-simulated barrier island profiles, varied XBeach input parameters, and output parameters calculated from the initial and final profiles are provided herein. Three sediment grain size distributions were considered, with distribution specified by median and 90th percentile, respectively: (0.2 mm, 0.3 mm), (0.4 mm,0.6 mm), and (0.6, 0.8 mm). All other XBeach input parameters were set to their default values.
