Component 2 EQ 5

Question 1

Why is the flood risk increasing in the U.K?

Answer 1

• People are building on flood plains
• People are removing meanders
• The upper course wetland is being destroyed
• There aren’t enough flood defences

Question 2

How does build on flood plains increase the risk of flooding?

Answer 2

There are more properties that can be flooded, and urbanisation is one of the reason the river discharge increases.

Question 3

How does removing meanders increase the flood risk in the U.K?

Answer 3

Although making rivers straighter puts water in the ocean quicker, meanders store lots of water. This means that they stop flash floods from happening.

Question 4

How does removing the upper course wetland increase the flood risk in the U.K?

Answer 4

The upper course wetland is much better for infiltration, so more water can be stored there, and it also has more vegetation, so more water is used up.

Question 5

What hard engineering types are used to manage rivers?

Answer 5

Flood walls, Levees and flood barriers

Question 6

What soft engineering types are used to manage rivers?

Answer 6

Flood plain retention and River channel restoration

Question 7

Do people prefer sort of hard engineering types?

Answer 7

People tend to prefer soft engineering types

Question 8

Which are cheaper, soft or hard engineering types?

Answer 8

Soft are cheaper

Question 9

Which are better at stopping floods?

Answer 9

Both tend to stop floods, however soft tend to work better
