Waves
Destructive waves are waves with a weak swash and a strong backwash, the name tells us that it takes sediment away from the beach
Constructive waves are waves with weak backwash back strong swash, its in the name it constructive it builds up the beach by swash the sediment on there
Longshore drift means what way the sediment is carried along the beach due to the direction of the prevailing winds
headlands
-
headlands can form bays because it has rocks bands such as clay and sandstone which erode quickly forming bays
soft engineering
Soft engineering is where the natural environment is used to help reduce coastal erosion and river flooding. At the coast soft engineering is where a beach is used to absorb wave energy and reduce erosion. ... Beach reprofiling is used after a storm event as the beach will have been unevenly eroded.

Depositional landforms
A tombolo is formed when a spit connects the mainland coast to an island. A spit is a feature that is formed through deposition of material at coastlines. The process of longshore drift occurs and this moves material along the coastline. ... The backwash takes it back out towards the sea at a right angle to the coast.
hard engineering
Hard engineering involves building artificial structures which try to control natural processes. Each engineering strategy has its advantages and disadvantages.
