This dissertation aims to investigate the impact of tides, waves, and interaction between the waves and tides on the sediment movement at a nascent tidal inlet, the Old Inlet Breach, at Fire Island, New York, that was opened by Hurricane Sandy in 2012.This study evaluated the hydrodynamics and sediment transport at the Old Inlet Breach using the data from the bathymetry survey and the Coupled Ocean-Atmospheric-Wave-Sediment Transport model. The observation and model data reveal the tidal variation of the current, wave, and sediment transport structure. Since the tidal current behaves like the potential flow when approaching the inlet throat and leaving it as an inertia jet, the current is flood-dominant on the flood shoal and ebb-dominant on the ebb-shoal. The resultant tidally averaged sediment transport into the bay and towards the ocean from the inlet throat builds up the flood or ebb shoal system while pushing the sand bar at the ebb-shoal edge towards the off-shore. The energy and momentum balance diagnosis shows that the tidal modulation of wave-breaking-induced water level set-up can reduce the ebb jet speed and boost the flood jet speed. The resulting bottom stress alternation can decrease sediment transport towards the ocean and increase the sediment transport going into Bellport Bay by 30% during the storm at the tidally averaged time scale. Such a change in along-channel sediment transport distribution can mitigate the erosion at the inlet throat and lower the ebb-shoal expansion rate.
