Coastal Management - Hard and Soft Engineering

Methods of managing the coastline that involve the construction of significant structures to try and prevent or reduce natural processes are known as:

• coastal management

• hard Engineering

• soft Engineering

Strategies used by people to prevent coastal erosion and flooding are known as:

• coastal management

• hard Engineering

• soft Engineering

Methods of managing the coastline that involve understanding and working with natural processes rather than trying to prevent them are known as:

• coastal management

Managed retreat allows an area of land to flood to protect other areas. Which of these describes the likely use of the land nearby?

• There is a large town behind the beach, so it doesn't matter if it floods.

• There is a holiday park behind the beach so it doesn't matter if it is eroded.

• There is low quality farm land behind the beach so it doesn't matter if it floods.

Why are beaches important? (Choose 2)

• They cause long shore drift.

• They attract visitors, and therefore bring economic opportunities to an area.

• They can protect the coastline from erosion by forming a barrier.

• They are made by destructive waves.

In Bournemouth, groynes have been constructed across the beach. How do groynes work?

• They trap sediment being carried by longshore drift and so build up the beach.

• They form a barrier between the sea and the cliffs.

• They absorb wave energy so the cliff is not eroded.

Select one consequence of building groynes along the coast?

• Beaches further along the coast will increase in size

• All other sea defenses stop working.

• Beach sediment is cut off so beaches further along the coast shrink.

• There are no consequences further along the coast.
