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]
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).

Beach cusps – Shoreline formations made up of various grades of sediment in an arc pattern; Beach ridge – Wave-swept or wave-deposited ridge running parallel to a shoreline; Bight – Shallowly concave bend or curve in a coastline, river, or other geographical feature
The construction of the MRGO, which breaches the natural barrier of the Bayou La Loutre ridge and the Borgne land bridge, has allowed sea water to push farther into the basin. Relative sea level rise of up to 0.96 feet per century also gives saltier waters greater access to surrounding wetlands. As a result, mean monthly salinities have ...
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.
Shore erosion is a natural process for lakes, but one that was made worse when high water levels of 2019-21 resulted in property damage. Lake Michigan shoreline erosion continues, despite lower ...
A Living shoreline is a relatively new approach for addressing shoreline erosion and protecting marsh areas. Unlike traditional structures such as bulkheads or seawalls that worsen erosion, living shorelines incorporate as many natural elements as possible which create more effective buffers in absorbing wave energy and protecting against ...
