Methods Of Preventing Flooding

Question 1

What is soft engineering?

Answer 1

Soft engineering is using natural materials to reduce the impacts of flooding.

Question 2

Name of the Chinese hard engineering structure on the Yangtze River:

Answer 2

Three Gorges Dam

Question 3

What is hard engineering?

Answer 3

Hard engineering strategies are those of which use man made materials to lower the risk of flooding.

Question 4

What are some hard engineering techniques to reduce the effects of flooding?

Answer 4

River straightening (Mississippi River) speeds up water past important areas.

The building of bridges/dams (Yangtze River) reduces the chances of flooding downstream.

Question 5

What are some soft engineering methods of flood prevention?

Answer 5

Afforestation (Yellow River, China) increases interception.

Flood plain zoning (Rhine River, Germany) increases the amount of permeable material for water to infiltrate into.

Warnings and preparation (UK) Environment Agency give alerts and warnings in order to reduce the impacts of flooding on specific areas
