What are the characteristics of coastal areas?
The coastal environment is the area lying at the interface between land and the sea. The area includes both the zone of shallow water within which waves are able to move sediment and the area landward of this zone including beaches, cliffs and coastal dunes. The landward zones are also affected to some degree by waves, tides and currents.
Most coastline landforms are in dynamic equilibrium with prevailing processes. Whether or not a coastline will exhibit erosion or accretionary characteristics is governed by a combination of sediment supply, weather patterns and the long-term relative change in sealevel.
