A GIS Compilation of Vector Shorelines and Associated Shoreline Change Data for Breton Island, Louisiana: 1869-2014 A GIS Compilation of Vector Shorelines and Associated Shoreline Change Data for Breton Island, Louisiana: 1869-2014
Many barrier islands in the United States are experiencing substantive erosion and elevation loss due to storm surge, waves, and sea-level changes; this is particularly true for the deltaic barrier system in Louisiana. Breton Island is located near the mouth of the Mississippi River in the southern end of the Chandeleur Island chain in southeast Louisiana. This report expands on previous

Characterizing bathymetric change in coastal environments is an important component in understanding shoreline evolution, especially along barrier island platforms. Bathymetric change is a function of the regional sediment budget, long-term wave and current patterns, and episodic impact from high-energy events such as storms. Human modifications may also cause changes in seafloor...

Integrating geophysical and oceanographic data to assess interannual variability in longshore sediment transport Integrating geophysical and oceanographic data to assess interannual variability in longshore sediment transport
Despite their utility for prediction of coastal behavior and for coastal management, littoral sediment budgets are difficult to quantify over large regions of coastline and over short time scales. In this study, bathymetric change analysis shows differences in the magnitude and spatial location of erosion and accretion over three years; more net accumulation occurred at the littoral end...
