Abstract: Louisiana contains 25 percent of the vegetated wetlands and 40 percent of the tidal wetlands in the 48 conterminous States. These critical natural systems are being lost. Louisiana leads the Nation in coastal erosion and wetland loss as a result of a complex combination of natural processes (e.g. storms. 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 at the foot of the Gulf of Mexico on the Eastern half of the state's coast. In the last century, Southeast Louisiana has lost a large portion of its wetlands .
Recent U.S. Geological Survey research focused on better understanding the physical processes that contributed to historical wetland loss in coastal Louisiana and the spatial and temporal trends of that loss. The results of this study provide the first comprehensive analyses of the three-dimensional aspects of historical wetland loss in coastal Louisiana and . Lake Pontchartrain and adjacent lakes form one of the largest and most important estuaries in the Gulf Coast Region. The estuary drains the Pontchartrain Basin, an area of o square kilometers situated on the eastern side of the Mississippi River delta plain. In Louisiana, nearly one-third of the state population lives within the 14 parishes of the Pontchartrain Basin.

The Louisiana Coastal Zone along the north-central Gulf of Mexico represents one of America's most important coastal ecosystems in terms of natural resources, human infrastructure, and cultural heritage. This zone also has the highest rates of coastal erosion and wetland loss in the nation because of a complex combination of natural processes and anthropogenic activities Cited by:

Lafayette, LA Coastal Louisiana wetlands are one of the most critically threatened environments in the United States.
These wetlands are in peril because Louisiana currently experiences greater coastal wetland loss than all other States in the contiguous United States Cited by: This project assesses the physical controls of sediment and material exchange between wetlands and estuarine environments along the northern Gulf of Mexico (Grand Bay Alabama/Mississippi and Vermilion Bay, Louisiana) and the Atlantic coast (Chincoteague Bay, Virginia/Maryland).
“Coastal wetland change is a long-term process.” Coastal wetlands help to reduce inland flooding and erosion and act as essential habitat for fish, shellfish and other wildlife.
Louisiana’s coastal wetlands provide benefits far beyond its borders, supporting more than 30 percent of the United States’ commercial fishing catch and protecting five important. Coastal wetlands disappearing. While Louisiana has 40% of the country’s wetlands, over 90% of the total coastal marsh loss in the continental U.S.’s occurs in the state.
It is estimated that between square miles of wetlands are lost each year and more than 1, acres have been lost since the turn of the century.
Shoreline Change: The following are shoreline change posters from the USGS Open-File Report in PDF format for the Louisiana barrier islands.
The Data Catalog includes the earliest shoreline used in the shoreline change calculations and the recent shorelines used except in the case of the North and South Chandeleur barrier islands.
Coastlines are constantly changing landscapes that pose fascinating science questions as well as unique management challenges.
The National Assessment of Coastal Change Hazards (NACCH) provides robust scientific findings that help to identify areas that are most vulnerable to diverse coastal change hazards including beach and dune erosion, long-term shoreline change. Graph of land area change rate in coastal Louisiana from – The red line approximates the long-term land area change rate.
