China is kinda stuck between a rock and a hard place right now. If they increase flow output, it will certainly cause major flooding downstream in places like Wuhan. If they maintain the 3GD how it is right now, it could end up collapsing the entire structure and gutting most of the Yangtze river valley, parts of the river upstream, and large parts of southern China. Likely why they've been intentionally breaking dams along the stream, flooding lesser known, lesser populated towns/cities to try and take the pressure off the 3GD for the moment. But you have to wonder whether severe flooding in Wuhan might be preferable to a collapse. I guess they've still got about 10 meters of water to try and work with, but all it takes is a dam collapse upstream or a geological event at the wrong place and wrong time to send ~170 m of water crashing into the Yangtze river basin.
This is so fucked for China. And while randoms on /pol/ are acting gleeful in the event it occurs, it would significantly affect the global economy—including pharmaceuticals and automotive parts. This is such a shitshow that it's preferable to flood hundreds of thousands of people's homes on purpose in an attempt to subvert the flooding of hundreds of millions of people's homes.
Two other points. 3GD might not flood tomorrow or this week, but the height of the rainy season seems to be in late July/early August. Even if they get out of the issue today, we could still see some catastrophe happen in the next month. Also, the issue is only going to get worse in the coming years. Rains will increase in this period, as they have been in recent years, if trends continue, and the 3GD is only going to be worn down even more. This is basically the worst ecological catastrophe waiting to happen—and it's near assured, as far as I can tell. China is fucked. Let's just hope they don't take down us as well.
