They alter ecosystems and disrupt fish migration. They also stop the spread of alluvium.

Question 64

Name four reasons why flooding has recently increased

Answer 64

Population growth Building on flood Plains Clearing trees for building Heavier rainfall due to climate change

Question 65

How does population growth affect current flooding?

Answer 65

More people are living in town built along rivers

Question 66

How does the clearing of trees affect flooding?

Answer 66

Because trees would’ve absorbed excess rainfall

Answer 68

This would prevent the river from bursting its banks.
