Three Gorges Dam Presentation
Transcript of Three Gorges Dam Presentation
By Eugene Bang & Irene Ra
What is it?
World's Largest Hydropower Project.
Yangtze River, Hubei Province - July 4 2012.
Produces 18,000 megawatts.
Most notorious dam.
1.2 million displaced.
13 cities, 140 towns, 1,350 villages flooded.
600 kilometres long reservoir.
Cost $59 billion.
70% rise in "Geological Hazards" - Landslides.
Polluted Waters - Waste water discharge doubled from 2000 to 2005.
Less rain/More drought.
Possibility of earthquakes.
Loss of Biodviersity
Three Gorges area is known for its rich biodiversity.
20% of Chinese seed plants.
Reduced water flow, changed weather and flooding.
Deforestation and pollution leading to endangered species.
Fish population decrease.
Delta of Yangtze - 25 of 177 fish species endangered.
Decreased flow of water leads to lowered water levels and fragmented lakes - Baiji Dolphin.
What's Being Done About It?
The government/corporation/Chinese people win.
Local residents/residents along the Yangtze lose.
Nobody wins - everybody loses.
The Diversion Of Water
South-to-North Water Diversion Project
Siltation --> Less run-off
Decline in fisheries.
At maximum water level of 175m - Dam's reservoir contains 39.3 cubic km of water.
This water weights 42 billion tons.
Moment of Inertia --> Slowed Rotation of Earth.
Water Rights and Stakeholders
Energy Needs and Demand
11% of China's hydroelectricity
Equivalent to 12 nuclear reactors.
More than hydropower capacity of the US.
Substitutes 30 billion tons of coal.
Possible Solutions (whilst meeting energy requirements)
REMOVAL OF THE DAM
INCREASING ENERGY EFFICIENCY.
The Three Gorges Project Development Corporation
The residents along the Yangtze River
Recognition of problem.
Cleanup and foritification.
Increase Energy Efficiency
+ Partial Decomissioning
+ Environmental Control
= Holistic Approach
THANK YOU FOR LISTENING ^^ !
