The addition of sand and sediment to an eroding beach by humans. The new material will be eroded by the sea which saves the cliffs or sand dunes from erosion and recession.
A form of mechanical erosion were material and sediment in the sea is flung at the cliff-face as waves break against it, this breaks up the rocks making up the cliff.
A concordant coastline with several river valleys running perpendicular to the coast. They become flooded to produce parallel long islands and long inlets
A system where its inputs and outputs are in balance. Short term changes can affect this balance, negative feedback loops help to take the system back to dynamic equilibrium.
The point at where the river meets an ocean, often muddy or silty. Sometimes estuaries become exposed at low tide or hazardous to traverse in a boat due to sandbanks.
Long narrow inlet of sea water which is between steep mountains. They are created when sea levels rise relative to the land, flooding coastal glacial valleys.
A form of hard-engineering. Low-lying concrete or wooden walls, constructed perpendicular to the seafront and run out to sea. They encourage the trapping of sediment to reduce erosion caused by longshoredrift or by winds.
Large sections of coastline (often sediment cells) are managed with one integrated strategy and management occurs between different political boundaries. It usually follows a holistic approach and takes into consideration different players.
Where there is a large downhill movement of material usually from a cliff-face. Here, the rock is often weak due to erosion and the movement is caused by gravity.
The area before the shore where the wave steepens and breaks before they reach the shore and then reform before breaking on the beach. It extends from the low-tide zone and then out to sea.
A form of transportation where smaller sedimentbounces along the sea bed pushed by currents. This sediment is too heavy to be picked up by the flow of the water.
