Why did Sanmenxia Reservoir bring disaster to the people in the upper reaches of the Yellow River?

It was all because the leaders at all levels in Weinan, Shaanxi Province blindly opposed it, didn't know what to do, and finally screwed up!

First, we only know that high water level will flood more land, but we don't know that we can step up dike repair to reduce floods. We can ask the central authorities for money!

Second, in order to build a reservoir, Shaanxi has to emigrate, didn't 80 million people downstream benefit from it? Won't Henan and Shandong give some compensation? You 800,000 people are paired with 80 million people over there. There are 100 people supporting you 1 people, there is nothing to be afraid of! And you screwed up and you're still complaining. Who cares about you?

Third, when the Ministry of Water Resources was miserable by you in Shaanxi, it was impossible for you to let people not hold grudges! Although we can win a few defectors, we believe that building Xiaolangdi can liberate Sanmenxia. Nice try! Tongguan has been above sea level for decades, and it is still hanging at 328 meters!

Next, it is not too late to turn around quickly: the sandbars of Weihe River should be restored by themselves to prevent floods from flowing backwards in the main stream; The lower reaches of the Weihe River should be silted into an overground river, and the winding river should be straightened from the average slope below Xianyang. River length1.50km, with sufficient slope. The beach 500 meters away from the levee should be stripped year by year to reduce the elevation and facilitate flood discharge. The stripped sand is only used to heighten the levees and the beaches inside and outside the levees. Next, Sanmenxia can gradually increase the operating water level 1 m every year. Ten years later, the operating water level will increase to 328 m in non-flood season, and only enough flood control storage capacity is needed in flood season.

By the way, you can also ask Sanmenxia for some electricity. Ten years later, the speed of raising the operating water level may reach 2 meters per year. In another ten years, the operating water level will reach 348 meters. The next step is to consider whether it is necessary to raise the Sanmenxia dam to 380 meters!
