China says their massive dam is not about to burst. Brace yourselves.


We wrote here about the possibility of catastrophic floods in China when their much vaunted Three Gorges Dam (the world’s largest hydroelectric gravity dam) breaks.

The dam was a pet project of the late Premier Li Peng and a huge source of pride to the nation when it blocked and diverted Asia’s largest river, the Yangtze, in 1997. It spans the river in Hubei province, which includes the cities of Shanghai and Wuhan.

Beijing has now admitted that the dam “deformed slightly” after record flooding. Needless to say, the official Xinhua News Agency played down the problem by confessing that some nonstructural, peripheral parts of the dam had buckled. As you can see, the dam has definitely changed. The Chinese authorities attribute the change to the massive rains of 2020.

If you click through on the Tweet below you will uncover a Treasure Trove of information about the possibility of the breaching of the dam and the unimaginable consequences to China.

How unimaginable? Let’s start here.

So, let’s divert for a moment to what happens downriver if the Three Gorges Dam fails. A 100m-tall wall of water will rush out at more than 100 km/hr. In 30 minutes, Yichang and its 4 million residents will be engulfed.
Zero+1 hour, Jingzhou and 5.7 million people will be swept away.
Zero+5, the major industrial city of Yueyang (5.5 mil people) will sit 5 meters underwater.
Zero+10 hours, Wuhan (11 mil people) will face flooding of 6-8m in all major industrial and port zones.
Zero+15 hours, Jiujiang (another major PPE hub with 4.7 mil residents) will be hit with several meters of flooding. All cropland and infrastructure will be flooded and damaged.
Zero+24 hours, Shanghai’s neighboring city of Nanjing will see its port crippled.
