Coastal processes
How waves shape a coastline, and the management choices that follow.

What it is
Waves erode, transport and deposit. Constructive waves build beaches; destructive waves erode them. Longshore drift moves sediment along a coast in the direction of the prevailing wind.
Where it applies
GCSE geography physical topics.
How it works
Erosional landforms — headlands and bays, caves, arches, stacks, stumps, wave-cut platforms — follow from differences in rock resistance and from the same processes as rivers.
Depositional landforms — beaches, spits, bars — follow from longshore drift and from where energy drops.
Management splits into hard engineering (sea walls, groynes, rock armour) and soft (beach nourishment, managed retreat), each with costs, benefits and knock-on effects further along the coast.
How to use it in your work
For management questions, always include the knock-on effect: groynes trap sediment and starve the beach downdrift. That is the higher-level point.
Name a case study and use specific detail — place names, dates, figures.
Stack sequences want the order and the processes, not just the labels.
Where to get help
Your teacher and your board's specification — options differ enormously between centres, and yours is the one that counts. Bitesize covers the skills; the subject song runs the topics.
Revise this with a song
These are ours. We write revision songs because a lot of people remember a tune when they cannot remember a page, and because revising out loud in the kitchen beats staring at a highlighter.
