1Hard engineering involves..
- AA 'hold the line approach' where defences are constructed to prevent or reduce erosion
- BBuilding defences which work with their natural surroundings to reduce and prevent erosion
- CConstruction of man made coastal defences
2Soft engineering involves...
- AGreat expense to prevent any erosion from occurring by constructing coastline defences
- BWorking with natural systems (e.g. beaches) to reduce erosion by absorbing wave and tidal energy
- Cstrategies such as sea walls, groynes and gabions
3This image shows a groyne

- ARichtig
- BFalsch
4How do groynes reduce coastal erosion?
- AThe reduce the power of the waves by causing them to break out at sea
- BThey trap sediment by preventing longshore drift
- CTrapping sediment causes a beach to build up which provides a natural coastal protection, reducing a wave's available energy for eroding the cliff face

- ARichtig
- BFalsch
6Sea walls often have...
- AA recurved shape
- BHeights in excess of 10 metres
- CNo gaps within them
- DDrainage outlets
7The image shows

- AGabions
- BManaged retreat
- CRevetments
8People can build offshore reefs/barriers as a form of coastal defence
- ARichtig
- BFalsch
9Planting vegetation at the back of a beach prevents erosion by...
- Astopping any water from hitting the cliff face
- BAbsorbing much of the waves energy
- CHolding the sandy surface together, stopping the beach from eroding
- DPreventing tourists from being on the beach
10What is meant by cost-benefit analysis?
- AWorking out the cost of something
- BComparing the cost of a defence against the value of the area it would protect
- CIf something should be built or not
11Which of the following absorb the power of the waves?
- ABeaches
