Coastal protection
•Sea wall

prevent waves
breaking over
roads and flooding
buildings.

Coastal protection
•Beach nourishment
the addition of new
material to a beach
naturally, through

longshore drift or
artificially, through
the dumping of large
amounts of material.
Coastal protection
•Rip-Rap
large boulders
dumped on the
beach as part as
part of coastal
defences.
