Coastal erosion is defined as "the loss of coastal lands due to the net removal of sediments or bedrock from the shoreline." [ 5 ] South Louisiana is one of the main places being affected. In 1973, Louisiana State University published “Environmental Atlas and Multi-Use Management Plan for South-Central Louisiana” analyzing the issue and ...
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).

The bayou wetlands of Bataria Bay, Louisiana experienced increased shoreline erosion as a direct result of the Deepwater horizon oil spill. [17] This was determined by examining rates of wetland loss in the region from the year prior to the oil spill and contrasting that with the rates of wetland loss after the oil spill. [17]
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 ...
Diagram of accretion and erosion of sediments in a coastal system. Black arrows indicate accretion, and white arrows indicate erosion. Sedimentary budgets are a coastal management tool used to analyze and describe the different sediment inputs (sources) and outputs (sinks) on the coasts, which is used to predict morphological change in any particular coastline over time.
Shoreline management involves the long-term monitoring of watershed and shoreline revitalisation projects. [1] Freshwater shoreline management is frequently run by local conservation authorities through state, provincial, and federal lake partner programs. These programs have been used as a method of tracking shoreline change over time ...
Examples from erosion include: Koge Bay (Dk), Western Scheldt estuary (Nl), Chatelaillon (Fr) and Ebro delta (Sp). [6] There is an obvious downside to this strategy. Coastal erosion is already widespread, and there are many coasts where exceptional high tides or storm surges result in encroachment on the shore, impinging on human activity.
Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural. [3] On non-rocky coasts, coastal erosion results in rock formations in areas where the coastline contains rock layers or fracture zones with varying resistance to erosion.
