Monthly Meeting
Brian Marshall presents
"The Three Gorges Dam: an engineering success or
environmental desecration?"
730pm Thursday 23rd February 2012
The Three Gorges Dam (TGD) spans China's Yangtze River. It is currently the world's largest hydroelectric power station.
The dam's principal functions are to produce electricity, increase the
Yangtze River's shipping capacity, and reduce the potential for downstream flooding.
The dam is marketed as an engineering, social, economic and environmental success.
The latter claim is based on the dam providing renewable energy
Yet, as with many such dam projects, there is much controversy. This arises because the dam has flooded cities, towns and villages, thereby displacing nearly 1.3 million people, has a major impact on river-associated ecosystems, creates an increased risk of substantial landslides, and potentially increases the likelihood of seismic events.
At our February meeting Brian Marshall will present a "tourist's eye" view of the dam, consider some of the conflicting views and attempt to place such developments in a broader perspective.
