University of New Orleans Theses and Dissertations
Barrier islands are widespread and typically enclose landward basins connected to the ocean through tidal inlets. Low energy in the basin enables fine sediment accumulation and salt marsh formation. Sea Level Rise (SLR) causes loss of marshes due to their low elevations and inundation sensitivity. Both long-term trends in sediment supply due to SLR and episodic transfers of sediment due to storms are important to the sustainability of marshes and tidal basins. The trajectory of deltas, including the Mississippi River Delta (MRD), are also impacted by sediment supply. The redistribution of sediments (autogenic reorganization) within transgressive systems will determine their …
