Solo uno scivolo di sabbia rimane dopo che le case sul lungomare sono state distrutte con più in pericolo di distruzione a causa dell'erosione costiera a Glen Eden Beach, Oregon. Riprap - una costruzione di grandi rocce - protectscontro l'aumento del livello del mare sulla costa dell'Oregon dell'Oceano Pacifico. La misura temporanea può costare oltre $$1000 per piede lineare ed è sopportata in questo caso dal proprietario di abitazione.

Coastal erosion refers to the gradual or sudden loss of land along the coastline due to the action of natural processes such as waves, tides, currents, and weathering. It is a natural phenomenon that occurs worldwide and can have significant impacts on coastal ecosystems, communities, and infrastructure. Coastal erosion typically occurs in areas where there is a dynamic interaction between land and sea. It can be caused by various factors, including wave energy, storm events, sea-level rise, sediment availability, and human activities. The severity of erosion depends on these factors and the vulnerability of the coastline to erosion. The primary agent of coastal erosion is wave action. Waves continuously interact with the shoreline, eroding it through processes such as hydraulic action, abrasion, and attrition. These processes can gradually wear away the land, leading to the retreat of the coastline over time. Different coastal features are particularly susceptible to erosion. For example, cliffs and bluffs are prone to erosion along their base due to wave undercutting, leading to the collapse of the overlying material. Beaches can also experience erosion, resulting in the loss of sand and sediment. Dunes, which act as natural barriers against coastal flooding, can be eroded or destabilized, further exacerbating the vulnerability of the coast. Coastal erosion can have significant consequences. It can threaten coastal ecosystems, including habitats for various plant and animal species. It can also impact human settlements, infrastructure, and economic activities such as tourism and fishing. Additionally, erosion can lead to the loss of valuable land and the relocation of communities. Efforts to manage and mitigate coastal erosion include a range of approaches. These can include natural or nature-based solutions such as beach nourishment, dune restoration, and the creation of artificial reefs.
