Seawall
Overview
A seawall 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 wave
s. 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.
The coast is generally a high-energy, dynamic environment with spatial variations occurring over a wide range of temporal scales.
Coastal management
In some jurisdictions the terms sea defense and coastal protection are used to mean, respectively, defense against flooding and erosion...

Coast
A coastline or seashore is the area where land meets the sea or ocean. A precise line that can be called a coastline cannot be determined due to the dynamic nature of tides. The term "coastal zone" can be used instead, which is a spatial zone where interaction of the sea and land processes occurs...

Wave
In physics, a wave is a disturbance that travels through space and time, accompanied by the transfer of energy.Waves travel and the wave motion transfers energy from one point to another, often with no permanent displacement of the particles of the medium—that is, with little or no associated mass...
