Model results of the hindcast period from 1979 through 2019, supported by and in combination with both historical and the newly acquired 2018 – 2020 field measurements, elucidate on the physical oceanographic processes within the Bay that are relevant to development and management, such as the influence of the Liberty Development Island (LDI) construction on sediment transport patterns. The hindcast runs are additionally used to calibrate and evaluate model uncertainty. The calibrated models are then applied for the future period to develop time-series of wave and hydrodynamic conditions from 2020 through 2050 and the effect on shoreline change rates and sediment transport patterns within Foggy Island Bay, with and without the LDI construction. 480751 U.S. Department of the Interior, Bureau of Ocean Energy Management, Environmental Studies Program https://doi.org/10.13039/100012475 M17PG00046 10.67297/9A1ED1 https://boem.gov/awardpages/100433
