The … WebThis process of longshore transport is responsible for moving sediment up and down coastlines. It can sometimes lead to the development of barrier islands and spits—thin strips of beach that generally form parallel to the mainland. Before 1933, a single barrier stretched along the eastern seaboard of the Delmarva Peninsula in the United States. breeze by luminous
