#1 Standard eco doom and gloom. You are all going to die cos you are getting modern homes, electricity and sewage. What horseshit.

#2 Three Gorges Dam is a disaster in the making.

Archaeologically speaking? Said and done, long ago. Environmentally so? We'll let China's existing—and none too reassuring—track record speak for itself.

#4 As usual, the headline, and the story, are misleading, aimed at the people who will read the head line and nod their heads.

a host of threats such as -
1. conflicts over land shortages, sounds like a legal issue to me, not an ecological one.
2. ecological deterioration as a result of irrational development Could be a local planning and zoning problem, no?
3. erosion and landslides on steep hills around the dam. Were the hillsides steepened by the dam construction? If not, this is a continuing geological problem, not related to the dam.
4. algae bloom downstream from the Three Gorges and a deterioration in aquatic life. So this is really the only ecological 'disaster' and apparently, it hasn't happened yet.

Another Times-made mountain-from-molehill.

#6 Bobby, re: erosion & landslides, the dam does greatly accelerate this due to the way in which the water level scours much farther up the hillsides than would be the case if the river flowed freely. And it gets worse over time, as landslides raise the water level, which erodes farther up .....

#8 RE #6: Thanks, lotp; I can see that now. I thought you were a teacher, not an engineer!

#11 A while back, I think every rantburg discussion about Three Gorges included the word "fly-ash".

#12 The two points that make me wonder are related to the landslides and hydrological flow.

I'm not an engineer but I have heard that the seepage into the surrounding earth from raising water levels can cause serious trouble by undermining various geologic structures (if not the dam itself) I also know, from personal experience, that the underground flow of water can change dramatically and quickly. Did the engineers of this project adequately take all that into account?

Additionally they spoke about the reduction in flow rate of the feeder streams. This is causing polution backups and can cause other problems as well.

I still don't think that this would have been publicized at all if there weren't a much bigger problem underneath.

#13 The Fly-Ash Liberation Army will NOT be ignored!....the construction was shoddy - many times the level (% of flyash substituted for cementitious materials) of flyash allowed in structural concrete in teh U.S.

but hey! It made it cheaper and got rid of a lot of flyash...kinda communist, ya know?

#14 Alaska Paul has remained the King of 3-Gorges™, fwd'g a 3-Gorges newsletter periodically to me. Together, we marvel at what a collosal POS it is. We are both licensed civil engineers...YMMV :-)

#15 What's the over/under for a collapse in a year or two, Frank?

Bobby - my area of expertise is computing and robotics. On those topics I can claim some significant expertise. (And I do teach.)

OTOH my knowledge of hyraulics and materials is limited to some basic undergrad stuff. We're lucky to have Frank and Alaska Paul's real expertise on dams and bridges and such.

#17 no immediate danger - if they don't threaten Taiwan, but it has no long-term future with all the issues accurately portrayed above. It could hardly have been more badly done. Another ChiCom Success™

#18 From a June 2, 2003 update:

Water levels rise in Three Gorges dam, cracks reappear

a general inspection of the dam in mid-May revealed that repair work to fix large cracks on its 185 metre-high concrete face had not been completely successful.

"We found that some of the vertical cracks on the dam that were repaired have reopened, even though we put a great deal of money and effort into the repair work," Pan Jiazheng, an engineer, said in a speech following the end of the inspection.

"We have a long way to go, as we enter the third phase of the dam construction. I hope we will do our best to build a first-class project rather than a dam with 10-metre-long cracks," he said in the speech published by the Changjiang Water Resources Commission.

Mr Pan, 75, a member of the Academy of Sciences of China and the former deputy director of the Engineering Academy, added, "We should absolutely not be proud of ourselves."

The highly controversial project has been criticised as an environmental disaster and the destroyer of a cultural and historic tradition in the scenic gorges that have been the centre of life on the Yangtze river for millennia.

Naysayers have questioned whether the vast amount of energy generated by the dam, about 84.7 billion kilowatts a year, can be sold, while doubting the huge project's ability to control floods on the river's traditional flood plains hundreds of kilometres downstream.

#19 even the inspection reports have to be looked at in a political light. That's pathetic, and a recipe for disaster
