Specification 3.1.3.2 · Paper 1
Revise: Coastal Management Strategies and Case StudySea walls are usually concrete barriers built along the shore to protect the land behind from erosion and flooding. A recurved face reflects waves back towards the sea, helping prevent them from reaching the land. Sea walls provide strong, long-lasting protection where wave energy is high, so they can be suitable for valuable settlements and infrastructure.
Paper 2
Distinguish groynes, which trap sediment moving along the coast, from sea walls and rock armour, which protect the shore directly.
