Seawalls

Seawalls

It is a form of coastal defence constructed where the sea, and associated coastal processes, impact directly upon the landforms of thecoast. The purpose of a seawall is to protect areas of human habitation, conservation and leisure activities from the action of tides and waves.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.
