Geography Revision of Coastal Processes

Important 'wave' words:

Swash- the movement of water up the beach as a wave breaks.

Backwash- the movement of water down the beach as water from a wave returns to the sea.

Fetch- the length of the stretch of water that the waves have travelled across to reach the coast.

Prevailing wind- the direction the wind usually blows from.

Constructive and Destructive waves:

Constructive- these waves build up the beach because the swash is stronger than the backwash, they are often low waves in relation to their length.

Destructive- these waves erode the beach because the backwash is stronger than the swash, they are often high waves in relation to their length.

Erosion processes:

Erosion is the wearing away…
