Depositional landforms
Cuspate Forelands
Triangular-shaped headland that extends out from the main coastline. Occurs where a coast is exposed to longshore drift from opposite directions.
-
As vegetation begins to grow on the deposited sediment it helps to stabilise the landform and protect it from storms.
Example; Dugeness in Kent, pebble bech and marshland area
Spits
Long, narrow features which extends into the sea. Made up of sand or shingle. The sediment is moved along the coast.

Tombolos (offshore bars)
-
A beach that has formed between a small island and the mainland. Deposition occurs where waves lose their energy and tombolo begins to build up
Beaches
-
Swash occurs at an angle but the backwash runs perpendicular to the beach. Material is transported along the beach via longshore drift
Commonly found in bays. Wave refraction creates a low energy environment which then leads to deposition of sand or shingle.
-
Barrier Beaches (bars)
Can trap water behind them to form lagoons. Where beach is separate from mainland it is referred to as a barrier island.
