A seawall (also written as sea wall) is a form of coastal defence constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast. The purpose of a seawall is to protect areas of human habitation, conservation and leisure activities from the action of tides and waves. (Kamphius, 2010). As a seawall is a static feature it will conflict with the dynamic nature of the coast and impede the exchange of sediment between land and sea (Shipman & Stojanovic, 2007).
