On the Yangtze river in China
1 of 12
When was the dam completed
2006
2 of 12
What is it used for
To generate electricity from hydroelectric power for central and eastern China, including the city of Shanghai, which has a population of more than 13 million people
3 of 12
The dam will aslo reduce...
the flood risk for 15 million people and improve the navagation along the river.
4 of 12
What has been created behind the dam
A huge reservoir, some 660km long and 1km wide
5 of 12
What are the dimensions of the dam
2.3km long and 100m high

Impacts (2)
Many cultural monuments have been lost as a result of the flooding, including the Zhang Fei temple
9 of 12
Impacts (3)
between 1998 and 2004 the amount of sediment transported by the river below the dam fell by over 50%, resulting in increased erosion rates downstream. Sediment will accumulate behind the dam and this will enquire dredging
10 of 12
Impacts (4)
Afforestion is needed on the slope in the drainage basin, to reduce the amount of sediment washed into the water and the reservoir behind the dam
11 of 12
Impacts (5)
The dam will have a negative ecological and environment effect. Increased likelihood of landslidesin immediate area around the reservoir & many species, EG: White flag dolphin, will have their habitats disrupted
