Outline the main geographical processes relevant to Coastal Management.
There are many geographical processes that are related and relevant to coastal management.
Hydraulic Action: Waves crashing against a headland and entering cracks in the rock. The air that was already inside the crack is now compressed by the water, creating pressure and consequently eroding the rock. Blow holes are sometimes created by Hydraulic Action. This effectively can create coastal management as the eroding rock can effect the general shape of the land, people who have properties on the land or other areas of the land that are wished to be preserved.
Corrosion: Different minerals leave a salty residue on rocks, this being the result of them being wet by waves crashing against them and then the rock itself drying out. This salty residue then acts, chemically eroding with the minerals already present in the rock. This can be a cause for coastal management as many houses have been built on rock and put under danger from the erosion creating a possibility for the house the fall apart ontop of the eroding rock. The salt and mineral can also cause metal to rust which can become and issue for buildings and structures near the coast.
