Ripples in the sea caused by the transfer of energy from the wind blowing over the surface of the sea.
The distance over which the wind has blown.
The movement of a wave up the beach after the wave has broken.
The return flow of water down a beach after a breaking wave. Gravity means this is always at right-angles to the beach.
Erosion caused when rocks and boulders transported by waves bump into each other and break up into smaller pieces.
The process by which breaking waves compress pockets of air in cracks in a cliff. The pressure may cause the crack to widen, breaking off rock.
The wearing away of cliffs by sediment flung by breaking waves.
This is the chemical action of sea water. The acids in the salt water slowly dissolve rocks on the coast. Limestone and chalk are particularly prone to this process.
The zigzag movement of sediment along a shore caused by waves going up the beach at an angle and returning at right angles. This results in the gradual movement of beach materials along the coast.
The wearing away and removal of material by a moving force, such as a breaking wave.
The movement of eroded material.
Occurs when material being transported by the sea is dropped due to the sea losing energy.
These methods aim to stop the coastal processes from occurring. They tend to be expensive and short-term options. They may also have a high impact on the landscape or environment.
These methods try to work with nature to protect the coast. They are often less expensive than hard engineering options and are more long-term and sustainable, with less impact on the environment.
