1
Q
Explanation of a sea wall
A
Provides a physical barrier to flooding
Recruited wall dissipates wave energy
2
Q
Revetments
A
Comcrete or wooden structures placed along a Coastline to absorb wave energy
3
Q
Groynes
A
Woden, stone or steel structures placed just off right angles to waves to control LSD and trap sediment
4
Q
Rip rap
A
Concrete blocks or boulders placed at foot of cliff to take wave impact
5
Q
Gabbions
A
Small boulders placed in a wire-mesh cage to take wave impact
6
Q
Barrages
A
Large structures built to prevent flooding on major estuaries
