- Three Gorges Dam
- Defences Used
- 3600km of Levees along the Middle and Lower part of the River
- 46 Dams are planned or under construction on the River
- Biggest Dam is 3 Gorges
- Reservoir behind can store around 22km cubed of flood water
- 101m High.
- Locks built along side it
- Advantages
- Reduced major flooding from once every 10 years to once every 100 years
- Turbines in the Dam produce 22.5 gigawatts of hydroelectric power, enough to supply 3 % of China
- Now much safer to navigate up the Yangtze River, increased shipping as the reservoir is now deep, so increase in trade.
- Seen as a tourism attraction
- Disadvantages
- 1.3-2 million people have to relocate, 13 cities and 1352 villages will be submerged
- 1300 sites of cultural and historical interest will be destroyed e.g. Temple of Zhang Fei
- Expensive - £25billion
- Destroys habitats and endangers species e.g. River Dolphin
- Dam will trap sediment usually carried down the river which could lead to failure of the Dam and cause catastrophic flooding
- Defences Used
