A marsh terrace is an artificially created berm that is built in a wetland to prevent erosion, reduce wave energy, and improve habitat for wildlife. Marsh terracing is most common throughout the upper Gulf Coast of the United States , where it is used to prevent coastal erosion , with 980 linear km (609 mi) having been built in Texas and ...
Bayocean, Oregon, January 2020. Dynamic revetments, also known as "cobble berms" or "dynamic cobble berm revetments", use gravel or cobble-sized rocks to mimic a natural cobble storm beach for the purpose of reducing wave energy and stopping or slowing coastal erosion. [1]
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.
Sand dune stabilization is a coastal management practice designed to prevent erosion of sand dunes. Sand dunes are common features of shoreline and desert environments. Dunes provide habitat for highly specialized plants and animals, including rare and endangered species. They can protect beaches from erosion and recruit sand to eroded beaches.

The term erosion often is associated with undesirable impacts on the environment, whereas submersion is a sustainable part of healthy foreshores. Communities making decisions about coastal management need to develop understanding of the components of beach recession and be able to separate the component that is temporary sustainable submersion from the more serious irreversible anthropogenic ...
The Ike Dike is a proposed coastal barrier that, when completed, would protect the Galveston Bay in Texas, United States.The project would be a dramatic enhancement of the existing Galveston Seawall, complete with floodgates, which would protect more of Galveston, the Bolivar Peninsula, the Galveston Bay Area, and Houston.
Human coastal activities has led to the erosion and loss of plant life on sand dunes. [19] Plant life has been established as an important stabilizing factor of sand dunes and the loss of it will cause more erosion. To prevent this, noticeboards, leaflets, and beach wardens explain to visitors how to avoid damaging the area.
