Example of land loss in coastal Louisiana between 1932 and 2011; detail of Port Fourchon area. Coastal erosion in Louisiana is the process of steady depletion of wetlands along the state's coastline in marshes, swamps, and barrier islands, particularly affecting the alluvial basin surrounding the mouth of the Mississippi River.
Atchafalaya Basin. The wetlands of Louisiana are water-saturated coastal and swamp regions of southern Louisiana, often called "Bayou".. The Louisiana coastal zone stretches from the border of Texas to the Mississippi line [1] and comprises two wetland-dominated ecosystems, the Deltaic Plain of the Mississippi River (unit 1, 2, and 3) and the closely linked Chenier Plain (unit 4).

It is a much broader term than coastal erosion because land loss also ...
Land loss in coastal Louisiana 1932 vs 2011 Population density and low elevation coastal zones in Louisiana Aftermath of Hurricane Laura, Lake Charles. According to the EPA: "Rising sea level is likely to accelerate coastal erosion caused today by sinking land and human activities. The sediment washing down the Mississippi River created the ...
The Biloxi Wildlife Management Area lies in a region that is vulnerable to coastal erosion, and the marsh offers valuable ecosystem services such as storm-surge mitigation for settlements such as New Orleans, and high-tide shelter for small mammals. In July 2023, the Coastal Protection and Restoration Authority completed a project nearby ...
On June 26, 2011, volunteers, organized by the Coalition to Restore Coastal Louisiana, planted 1,600 black mangrove trees along the coast to prevent erosion. [17] It was named in 2020 to The New York Times' List of 52 Places to Go which noted that the site "may soon vanish" and faces one of the world’s highest rates of relative sea level rise ...
