Geographical processes that are relevant to coastal management are:
- swash - waves breaking on the beach, thus causing damage to the coast as the water eats at the beach.
- longshore drift - sand being moved across the beach.
- wave erosion - waves eroding against the beach
- tides - the water moves up and down throughout the day carrying with it items that could damage the coast.
- destructive waves - they destroy beaches by breaking quickly on the sand not allowing enough time for the water to soak into the sand.
- constructive waves - they build beaches by depositing sand along the beach
All of these processes destroy or help the making the of the coast.
