That's a lot of dam.

Jason Bontrager

They certainly don't think small.

I for one, welcome our new Sino overlords.

The dam’s over 2.3 kilometres in length, almost 200 metres high and over 100 metres wide at its base. It cost $26 billion and by September 2009 it had generated 348.4 terawatt hours of electricity. It’s expected to generate over 100 TWh every year. Which is quite a lot.

Dai Qing, an environmental activist, has been the most vocal opponent of the Three Gorges. She said: “We have never stopped talking about the problems but our voice was too weak. The system does not listen to the voices of civic activists or dissidents. But now, at last, they are starting to hear.”

One of the most worrying consequences of the project has been the sharp increase in landslides around the dam. Studies by geologists have shown that the water seeping out of the reservoir and the huge pressure changes are weakening the banks.

One official said that the shore of the reservoir had collapsed in 91 places and a total of 36 kilometres (22 miles) had already caved in.

Landslides have produced waves as high as 50 metres (165ft). In July a mountain along a tributary collapsed, dragging 13 farmers to their deaths and drowning 11 fishermen.

Ms Dai told The Times: “The Government knows it has made a mistake. Now they are afraid that the catastrophe that they cannot prevent will spark civil unrest. So they want to go public before the troubles start.”

CHAPTER TEN

Dam Safety Analysis

by Philip B. Williams, Ph.D., P.E.


The consequence of failure at the Three Gorges Dam would rank as history’s worst man-made disaster. More than 75 million people live downstream on an intensively cultivated floodplain that provides much of China’s food. It is therefore reasonable to expect that a key design criterion for the project is ensuring that the risk of failure is kept extremely low.

Because of the limited operating experience with large dam projects of this type, and the disquieting number of safety incidents that have threatened the integrity of large dams in the last two decades, it is reasonable to expect that CYJV would use the best state-of-the-art techniques to demonstrate that the design, construction, operation and decommissioning of the project would keep the risk of failure acceptably low.

Unfortunately, CYJV does not address the safety issue either systematically or coherently. It provides no acceptable risk criteria, no mapping of the area and population at risk, no comprehensive risk assessment which identifies all the potential failure modes, and no identification of fail-safe measures. Because safety is not analyzed as a discrete topic, major failure mechanisms and combinations of failure mechanisms are ignored. There are many such possibilities; for example, a reservoir-induced earthquake that initiates new landslides close to the dam; sabotage or military action that disables spillway gates immediately before the flood season; unanticipated delays in construction leading to the overtopping and washing out of one of the cofferdams.*

More than 75million will be affected... check out the map:

Central Akanay (i.e. Central Southeast Asia = Isaan plateau) is already in the grip of drought.

The population of Thailand has been growing rapidly for decades, and lot of it is rural... the implications of China's action for Thailand are serious. There are already patches of desert in inland southern Vietnam, Thailand, Laos,m and Cambodia; this dam is a serious emergent geopolitical issue for the Asia-Pacific region.

Part of China's "String of Pearls" strategy to control the Indian Ocean and flow of resources shipping between the Near East and Africa, and the Chinese empire... which is spreading into Burma, Nepal, and Bangladesh, and even infiltrating India. Sinophiles have a lot of questions to answer; and we in the North Atlantic world need to reflect on whether we are content to stand idly by and watch this totalitarian empire grow.

I'm not an rabid environmentalist either... it's just shockingly grim and ugly to see a beautiful beach or bit of countryside covered in shit.
