3.3- Managing water supply

Water transfer schemes- Hard engineering 

• e.g. Chinas Transfer Project

• Divert water from surplus river basins in South and East to North where there’s water deficit

3 routes: western, eastern, central

Pros and cons

• 345,000 ppl relocated

• too much draining from Southern China

• Eastern route is industrial and risks further pollution

Three Gorges Dam- Hard engineering

• Dams block rivers so reservoirs of water build up

• Designed to control flooding on Yangtze, generate HEP, invoice water supply by regulating river
