“Allah’s name to begin with, the most Beneficent and Merciful.”

This dam will become the largest dam in the world after its completion.

Page 4: Dams

This dam is being build in the China on theYANGZI river. This river is the third

largest river in the world.

First of all the idea of dam on the YANGZI river was given by

SUN YAT SEN the father of the modern CHINA

In 1919.

Page 5: Dams

•It will become major source of electricity for china’s growing electrical

consumption.•It will provide a good restriction in

floods in YANGZI river which caused death of 1 million lives in

the past 100 years.•It will also be a large reservoir of

water.• Flood control, power generation,

improved navigation.

DamA Hydro Power Station for electricity.

Navigation Facilities for trade.

•It consists of three parts.

Page 7: Dams

This dam was the dream of many Chinesegenerations.

In 1950 after devastating floods in YANGZI riverMAO TSETUNG ordered feasibility studies on

damming the river. It will be completed in 17 years.

Its construction was started in 1993. It will be completed in 2009

•250,000 workers are involved in theproject.

•Amount of concrete used in the project is 26.43 million Cubic meter twice that of

ITAIPU project in BRAZIL currently world’s largest dam.

•After GREAT WALL it is the largest project In CHINA.

•Three Gorges reservoir will include 632 square Kilometers of land.

The ultimate structure

Page 9: Dams

•1.2 million people will be resettled by this dam.•New land is provided to 300,000 farmers.•This project will drew 13 big cities andmore than 100 towns.•1351 villages will be effected.•One of the tragedies of this [project], if just from a regional standpoint, is that the land that is going to be flooded is some of the most fertile in China.

Page 10: Dams

This project is environment friendly. CHINA burns 50 million tons of coal each year for

energy effecting environment due to sulphur and carbon dioxide. This project

will reduce the consumption of coal. Although due to this project some species will be disturbed but overall effect of the

project on the environment is friendly. Due to large consumption of coal carbon dioxide

and sulphur causes acid rains.

•This dam consists of 26 hydro power turbineswhich will produce 18200MW of electricity. This

capacity is equal to the output of 18 atomicpower plants.

•After this project CHINA has embraced an energy dinosaur.

•The reservoir will be 370 miles long and stores 39.3billion cubic meter of water.

Page 12: Dams

•This dam will be 525 feet deep.•Head of the dam is 185 meter high.

•1.2 mile stretch of concrete.•Cost of the project will be $37 billion.

•Annual power generation will be 84 billion Kilowatt-hours.

•One third of total cost of dam will be used for the resettlement of people.

•One ninth of the county’s total power Generated.

The impact to international trade is indirect.

Large amount of machinery is requiredfor dam that is imported.

Government has imported 680MW turbo generators and 50 KV high voltage

transmission lines.These equipments are expensive and

amount of International trade is significant.

Three Gorges Project Development Corporation intends to raise a quarter of the total project costs from overseas.

•People that are resettled are the main opponent of this project.

•WORLD WILD LIFE department strictly opposes this project…………..YANGZE

Dolphin, Chinese tiger will be demolished.

•Overseas Chinese Ecological society, friends of earth oppose the project.

•WORLD BANK also criticizes this project.

Page 16: Dams

A Chinese Journalist Dai Qing • She also calls for a halt to

construction and supports the idea of a series of smaller, less disruptive construction projects on tributaries of the Yangzi

• The River Dragon has Come

Page 17: Dams

•Environmental damages.•Risk of earthquakes and landslides

will increase.•It will also threaten the riverps wildlife. •Project will have a negative impact on

Chinese culture.•Due to this dam 800 sites of local

culture will be submerged.

•Real cost estimated to be closer to $77 billion

Page 18: Dams

• The dam will also destroy scenery and a source of tourism.

• Will destroy 1300 archeological sites.• Will flood many historical sites.• Erosion

Page 19: Dams

• Pollution from industrial and residential sources to concentrate in the river

• Silt accumulation.• Lose 115,000 acres of

arable land.

Page 20: Dams

This dam will play the role of back bone in China’s economy in future. Chinese Government fully supports this project.

China’s power output must rise 8%annually to keep pace with 6% annual Increase in gross national product. It

Supply mainly power to central China.

• symbol of their nation's vitality Employment Flood Control

Lessen the frequency of large floods from once in 10 years to once in 100 years.

Page 22: Dams

Supporters say the benefits of the project outweigh the costs.

Dam will relieve the danger of flooding.•10,000-ton ocean-going freighters to sail directly•Generated electricity is equal to the 40 million

tons of coal.•Replace high-sulfur coal (75% of energy supply)

Page 23: Dams

•Small dams vs three gorges dam

•Deep draft vessels can go as far inland as Chongqing

•Will increase transport by 400%

•Will provide energy to 60 million residents currently without power.

Page 24: Dams

And So…

Will this be a good or bad thing for China? No one knows, the benefits seem to match the pitfalls, and the Chinese have persevered for 5,000 years. Likened to the Great Wall in scope, only time will tell about…
