Coastal Management - Hard Engineering (AQA Geography 9-1)

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 be 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

• hard Engineering

• soft Engineering

What type of strategies are being used at Minehead, Somerset?

• Hard engineering: Sea Wall

• Hard engineering: Rock armour

• Hard engineering: Revetment

• Soft engineering: Managed retreat.

Managed retreat allows an area of land to flood to protect other areas. Why is managed retreat being used at Porlock?

• 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?

• Beaches are not important.

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

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

• They can protect the area next to the beach form flooding.

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.

What can be the consequence of building groynes further along the coast? Tick all that apply

• Beaches further along the coast will increase in size

• The rate of erosion can increase.

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

• There are no consequences further along the coast.
