Dunes that develop behind fore dunes. They may be stabilised by small shrubs and trees.
The movement of the water returning back to the sea.
Artificial placement of sand on a beach.
A hole in the roof of a coastal cave, produced by wave erosion, through which compressed air and water are forced as waves break into the cave.
Where the sea shapes the landscape by wearing away and breaking up the rock along the coast.
Small low-energy waves that deposit sand onto beaches.
The depositing of sand and rock particles caused by wind and wave action forming features such as beaches.
Large waves formed by tropical cyclones and storms that erode material from beaches.
The closest dune to the ocean or the first dune in a sand dune system.
An artificial structure designed to trap sand being move by longshore drift, therefore protecting the beach. Can be built using timber, concrete, steel pilings and rock.
Where waves enter cracks in rocks, air is compressed by the force of the water causing erosion and forming features such as blowholes.
The process, caused by waves hitting the coast at an angle, that is responsible for moving sand along the coast.
A submerged sand deposit normally running parallel to the shoreline. It is sometimes submerged during high tide.
A gently sloping rock ledge at the base of the sea cliff, caused by wave erosion.
A mass that forms along shorelines, usually composed of sand formed from loose particles of rock and other materials such as shells and coral.
Narrow deposit of sand and other materials that extends out into a body of water.
A column of rock, isolated from shore by the corrosive action of waves.
A dome of water, about 60-80 kilometres across and two to five metres higher that the normal tide level, resulting from an intense storm system.
Strategies that are designed to protect and preserve the coastal environment with the current population (as well as for future generations).
The movement of the waves up the beach.
