      * reforestation - This is one of the most heavily populated areas in the world here, it is not an option to reforest much of it.

      One of the causes of the flooding is deforestation; by preventing more loss of vegetation, and growing back what you can, you can increase how much water is absorbed before it enters the river. You have to keep in mind that while China is heavily populated, the actual population density isn't particularly high, and the Chinese government already has committed to reforestation projects, realizing their importance.

      levees, spillways, floodways - This will only go so far. I do not think it is feasible to do given how many millions of acres flood each moonson season. How many levees, spillways and floodways can you make?

      You don't just make new ones; you improve the ones that are already there. I think you're missing the point; the best way to prevent flooding is not in one huge grandiose project, but to improve flood control through a variety of methods. Again, these are also things that the Chinese government has already planned to do; however, I think they're putting too many eggs in the TGP basket.

      * creating a series of smaller dams - A serious of smaller dams, while indeed an alternative solution, is not necessarily better. What matters is how well each solution, a big dam, or several smaller, is implemented, and not choosing say smaller dams over one large one. Each solution has its own advantages and problems, one is not clearly better than the other.

      Moral relativism doesn't go far in engineering. Yes, a series of smaller dams would be more effective and less costly. It's a better solution. Especially considering you could more adequately control more of the river (the current location of the dam project is upstream from several tributaries, which will limit how effective it can be), they'd be easier and cheaper to make, and a catastrophic failure of one won't threaten as many people as if (or when) the TGD failed.

      Again, I think you're missing the point; I'm not saying the TGP dam couldn't help, I'm just saying that the way it's been implemented pretty much dooms it to failure. They have already spent billions of dollars (much of it siphoned off by corrupt officials), and plan on spending tens of billions more. This, in a country that is in a perpetual cash shortage. There's a reason the World Bank refuses to offer any funding, and the US Export-Import bank won't guarantee loans to US companies investing in the project. The TGP is just a horrible idea, executed in one of the worst ways possible, that will most likely fail in its mission, and cost thousands, if not hundreds of thousands of lives.

    Firstly, their human rights record is atrocious, but that has nothing to do with the Three Gorges Project per se, and I don't understand why you mention it in this context (it may also pay to note that the USA executed 85 people in 2000, so its hands are hardly clean (I realise this is far below the scale of China))

    Secondly, Large damming projects have often involved moving sections of the population. This is not unique to the Three Gorges Project. in that light, the archaeological treasures (i.e. things not readily moveable) need to have a high priority placed on them (not to the exclusion of the currently living human population). What hasn't been said is what compensation the Chinese government is making to the people it is moving. Without this information, it is hard to say whether they are being unreasonable or not.

    thirdly, to say China cares more about tourisim than its billions [sic, its about 1.3 billion] of people is a little odd. Tourism is a revenue generating process (typically FOR the people). Surely by promoting tourism (ideally in a slightly more eco-friendly way than Three Gorges) they are demonstrating that they care for the economic well being of the local people?
