The lower Yellow River has become a 'hanging river', accumulating 400 million tons of sediment every year, why not dig it up?

The Yellow River is affectionately called the "Mother River" because it has nurtured countless Chinese sons and daughters for thousands of years. But now with the accumulation of time, the riverbeds in many parts of the Yellow River have been tens of meters above the ground. In case of flood season, the Yellow River will become very dangerous. In order to prevent disasters, the local people have strengthened the Yellow River dams all year round. In this way, the danger of the river bursting during the flood season will be prevented. However, this approach is a temporary solution. Every year, hundreds of millions of tons of sediment are accumulated in the Yellow River, which in turn leads to an increase in the riverbed. Since such a problem has already occurred, why does the international Why don't you start to fix it?

If we want to deal with this problem, first we have to figure out how the sediment of the Yellow River is produced. Most of the sediment in the Yellow River comes from the Loess Plateau, where the sediment is extremely water-permeable and is especially easy to be diluted by the river water, so this is also the main cause of soil erosion in the Loess Plateau. Therefore, whenever the Yellow River flows through this place, it will sweep away a lot of sediment. According to statistics, the Yellow River accumulates 400 million tons of sediment every year. In addition, the lower reaches of the Yellow River are mostly located in plain areas, so the water flow will also slow down, and the accumulated sediment will increase year by year, which will lead to the elevation of the Yellow River bed.

Faced with this move, if the sediment at the bottom of the river is not dealt with in time, in case the Yellow River bursts its banks, the consequences will be unimaginable. Therefore, the local people will spontaneously raise the embankment. Then since the elevation of the Yellow River bed is so dangerous, why doesn't the country clean up the sediment at the bottom of the Yellow River? In fact, in response to the transformation and management of the Yellow River, the state has also taken many measures, such as building large-scale construction around the Yellow River and restoring plantings, but this approach has not fundamentally solved the problem of sediment in the Yellow River. Day after day, the amount of sediment accumulation will still be increase.

Now, is there really no way to clean up the Yellow River sediment? Some people have suggested before that it is possible to use large dredgers to clean up the sediment, but there is a problem that hundreds of millions of tons of sediment have been accumulated at the bottom of the Yellow River, and the weight of the sediment will continue to increase every year. Rise, if it were to be dealt with in this way, the cost would be enormous. More importantly, even if all the sediment at the bottom of the Yellow River is cleaned up, if it cannot be effectively used in the end, how to dispose of it is also a problem.

Therefore, there is really no proper way to clean up the sediment at the bottom of the river, but we can't clean up the sediment. We can use another method to solve this problem, that is, to reinforce and raise the Yellow River dam, and also Build more hydropower stations to solve flood disasters during the flood season.

With the continuous development of science and technology in China, I believe that in the future, we will have a suitable way to deal with the sediment problem in the Yellow River, and will also completely repair the soil erosion problem in the Loess Plateau.
