What is another word for seawalls?
Pronunciation: [sˈiːwɔːlz] (IPA) 
Seawalls are protective barriers erected along coastlines to prevent tides and waves from damaging coastal property and causing erosion. Synonyms for the term "seawalls" include retaining walls, bulkheads, breakwaters, and revetments. Retaining walls support and retain soil along waterfronts and on slopes. Bulkheads refer to a similar structure that helps prevent soil erosion and water damage. Breakwaters are built offshore to create calm waters in the area behind them. Revetments are sloping walls made from materials such as rocks or concrete and provide an added layer of protection against the forces of waves and tides. All of these structures serve the same purpose, to provide protection against damaging natural forces near the coastline.
