The study, conducted by researchers at UC San Diego’s Scripps Institution of Oceanography, also identified hot spots in areas both north and south: The rate of cliff collapse was more than 16 ...
Coastal erosion. Heavy marine erosion: cliff fall at Hunstanton in the east of England. Sea erosion at Valiyathura Kerala, India. Tunnel-like structures formed by erosion in Jinshitan Coastal National Geopark, Dalian, Liaoning Province, China. Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks ...
Tetrapod (structure) Tetrapods protecting a marina on Crete, Greece. A tetrapod is a form of wave-dissipating concrete block used to prevent erosion caused by weather and longshore drift, primarily to enforce coastal structures such as seawalls and breakwaters. Tetrapods are made of concrete, and use a tetrahedral shape to dissipate the force ...
Beach grasses planted to prevent erosion at Island Beach State Park, New Jersey. 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 ...
Sand dune stabilization. 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 ...
Groyne. A groyne (in the U.S. groin) is a rigid hydraulic structure built perpendicularly from an ocean shore (in coastal engineering) or a river bank, interrupting water flow and limiting the movement of sediment. It is usually made out of wood, concrete, or stone. In the ocean, groynes create beaches, prevent beach erosion caused by longshore ...
Coastal erosion is threatening beachfront homes and a popular railroad route in San Clemente, California. The Pacific Ocean's powerful swells have reclaimed much of the Cyprus Shore community's ...
Soft engineering: Beach nourishment is a type of soft approach. it gained popularity because it preserved beach resources and avoided the negative effects of hard structures. Instead, nourishment creates a “soft” (i.e., non-permanent) structure by creating a larger sand reservoir, pushing the shoreline seaward.
