How should river be managed?

Question 1

Should we change out approach?

Answer 1

• Yes councils should move to soft engineering

- But no climate change - rivers rising so need hard engineering

Question 2

Give two examples of soft engineering?

Answer 2

• Afforestation

- Planing restrictions

Question 3

Explain Afforestation

Answer 3

Tress intercept water with leaves. Slows river movement and stores water (Vegetation storage)

Question 4

Explain Planning restrictions

Answer 4

Stop development on food plains and limit uses to agricultural (Low value land)

Question 5

Why is Soft engineering good?

Answer 5

Cheaper options and have little impact on environment

Question 6

Give three examples of Hard engineering?

Answer 6

Dams
Dredging
River engineering

Question 7

Explain Dams

Answer 7

Control water to create lakes and limit flood downstream

Question 8

Explain Dredging

Answer 8

Removes slit and sand from the river bed to increase the channel’s capacity

Question 9

Explain River engineering

Answer 9

Straightening the channel allows faster flow of water to the sea

Question 10

Why is Hard engineering bad?

Answer 10

Expensive and requires maintenance. Larger impacts on the environment
