Answer 12

Slopes are Reinforced By Inserting Concrete Nails into the Ground and Covering the Slope with Metal Netting.

Question 13

What is Strategic Realignment?

Answer 13

Removing an Existing Defence and Allowing the Land Behind it to Flood.

Question 14

Benefits of Sea Walls?

Answer 14

Prevents Erosion and Acts as a Barrier to Prevent Flooding.

Create Wider Beaches which Slow the Waves. This Gives Greater Protection From Flooding and Erosion. They’re Fairly Cheap.

Question 16

Benefits of Beach Replenishment?

Answer 16

Creates Wider Beaches which Slow Waves Giving Greater Protection From Flooding and Erosion.

Question 17

Benefits of Slope Stabilisation?

Answer 17

Prevents Mass Movements By Increasing the Strength of the Slope.

Question 18

Benefits of Strategic Realignment?

Answer 18

Over Time the Land will Become Marshland - Creating New Habitats. Flooding and Erosion are Reduced Behind the Marshland.

Question 19

Costs of Sea Walls?

Answer 19

Creates a Strong Backwash, which Erodes Under the Wall. Sea Walls are Very Expensive to Build and to Maintain.

Question 20

Costs of Groynes?

Answer 20

They Starve the Beaches Further Down the Coast of Sand, Making them Narrower. Narrower Beaches don’t Protect the Coast.

Answer 21

Taking Material From the Seabed can Kill Organisms. It’s Very Expensive and Has to be Repeated.

Question 22

Costs of Slope Stabilisation?

Answer 22

It’s Very Expensive and Difficult to Install.
