Many people believe that in ancient times, the Yellow River was clear, but in fact, in the late Warring States Period, the river was already called a "turbid river". The large-scale collapse of the river was directly related to the changes in celestial phenomena. From the late Emperor Yao to Shun
From the emperor's period to the era of Dayu, during the decades between the three generations, it was the time when the entire mountains and seas were changing from a "cold period" to a "warm period"!
In other words, the accumulated ice and snow from the ancient Three Emperors era has been melting year by year, and the rivers in the Western Wilderness have flooded wantonly in the no-man's land. This warm period will fluctuate during the Shang Dynasty, and finally in the early Western Zhou Dynasty.
reached its peak in the year.
In addition, two hundred years ago, the emperors fought fiercely. The Yellow Emperor's old tribe rose up in the Western Wasteland and moved to the east bank of the river. The Yan Emperor also flourished on the Loess Plateau. In this era, although there was no construction of palaces, due to the
After months of fighting against nature, whether it is building a house, making tools, making fire, or boiling water, every activity requires the use of wood.
Although people in ancient times also knew the principle of "living in harmony with nature", for example, burning mountains would delineate areas, but this was also because everyone needed wood to make homes, so they could not burn mountains at will. Therefore, "planting trees"
This kind of behavior is basically non-existent.
There are many trees, and they are growing every year, but the growth rate has begun to tire. Human activities and survival needs have exceeded the self-recovery ability of natural trees. When a wilderness is opened, countless trees turn into fireworks and disappear.
In the ancient smoke, trees that had existed in ancient times were burned one by one.
In addition to human activities, the earth's own anger and weather erosion are also the reasons why this land is riddled with holes, which are the traces left by the years.
In the late Pliocene, the ground of the Loess Plateau rose, and the Yellow River and its tributaries, the Tao River, the Zuli River, and the Hulu River, cut downwards with the uplift, and the bedrock ground became more undulating and hilly.
Purple clay, sandy clay, sandstone and gravel containing gypsum are widely present. These materials have poor lithogenesis and weaker corrosion resistance. They are prone to gravity erosion under the immersion and lubrication of groundwater. As a result, large landslides occur one after another.
Appear.
The high-altitude primary loess can be traced back to the Ice Age of the Quaternary Period. At that time, the sky and the earth were frozen, and countless dust accumulations were superimposed here year after year. The later loess is secondary loess. These are the processes
Alluvial, accumulated by floods.
This land is a place where "neo-tectonic movement" is extremely active, which is why the soil here is so easily eroded. In addition, the Yellow River is in the monsoon area. Once it encounters heavy rain, it is particularly easy to rise, accelerating soil erosion and
Landslides cause natural disasters such as mudslides, and eventually lead to catastrophic floods.
The Pliocene Epoch is 5.3 million years away from this time, and the Quaternary Epoch began 2.6 million years ago.

In the mountains in the western sky, the ice and snow have not yet melted, but the rivers can no longer hold back and are about to wake up and cause chaos. Chong Bogun has already foreseen that if the floods cannot be suppressed this winter, then next year, the world will return to spring.
, on the mountains of the Western Wilderness, thousands of rivers will flow together, and the river will completely turn into a furious dragon, tearing the entire Central Plains apart!
"My water blocking method, these river embankments built will definitely be able to block the flood. I have tried it on floods in previous years. The areas with river embankments have successfully diverted water and prevented the flood from reaching them.
Both sides of the Taiwan Strait..."
“Where there are river embankments, where Rencheng City was built, the riverbanks have never collapsed... After nine years, this continuous river embankment and this far-flung city group will successfully lead the flood into the East China Sea.
"
"The Emperor of Heaven appointed me to be Sikong, and I will be here to watch the river fall asleep again!"
Chong Bogun was doing the final mobilization work for the people of the Chong clan, the Fanghu clan, and the Xuanyu clan.
This is a challenge. The Emperor of Heaven has given them the important task of controlling floods, and they must shoulder it, because thousands of tribes have been plagued by floods for hundreds of years.
There have been clues since the time of Zhuolu. In the past two hundred years, the world has gradually become active. Floods have continued one after another, and rivers have collapsed one after another. The people on both sides of the river have suffered greatly, and this suffering must end this time!
After many experiments and floods in the past few years, although the floods were not very big, the river embankment has shown a very strong defense. As long as the river is allowed to follow its original trajectory, there will be no
question!
"Father!"
Behind the people of the Chong family, some young people came running. Another year passed and he was one year older. Wen Ming was already an adult at the age of thirteen and was about to turn fourteen. He also grew taller.
, although he still has a little childishness, but he is already an excellent warrior who can stand alone.
"Father, just blocking the water is not enough. It also needs channeling, diversion, and even barrier lakes. This levee alone may not be able to withstand this flood!"
"I've seen it. The water level of the river has risen. It's much higher than the previous times! The water flow is also much faster!"
Gun looked at Wen Ming. He was walking in front, and many people from the water control tribe made way for him. At this time, Gun stared at Wen Ming and said seriously: "You are still young, and you have not personally practiced some of the methods of water control.
."
"Gonggong once blocked hundreds of rivers, dredged up silt, and built huge dams. In the end, the floods were still unstoppable, and the mountains collapsed and shook. The sound shook the heavens and the earth, and frightened the gods..."
"After you came back from the south, He Shuizheng told me that everything needed to be diverted. But I also told you that diverting water was something Gonggong had done before. It cut off the water in the big river and diverted it out, turning it into a river.
There were a lot of lakes, but in the end those lakes were also mobilized by the flood, and instead collapsed and re-entered the river, causing an even greater disaster!"
"You said that the water control man in the south said that we should adapt to local conditions. The river collapses from time to time. When I build river embankments, aren't I adapting to local conditions? What he said and the methods that can be tried, we have already tried most of them!"
The water with the Chong family was silent. After they came back from the south, they were very happy to tell Chong Bo Gun's new method of water control. But after Chong Bo listened, he gave explanations and responses one by one, and told them
Some things and many methods have been "used" by Gonggong.
In the end, it was of no great use, so Gun discovered the source of the problem. The more he worked on it, the more troublesome it became, but he couldn't let it go, so he built this huge embankment project to minimize human intervention and wanted to guide the people correctly.
water.
"That's different!"
Wen Ming advised: "Father, what I saw in the south is that the way they drive the water is different from what you and Gonggong do. The words are the same, but the actions are different. Your embankment
, I have heard Brother Zai say that if we fail to manage it correctly and just increase the dam height, if the river becomes a hanging river above the ground, then the change will be dangerous!"
"Some things need to be surveyed and calculated. No matter how solid things are, they are afraid of the mighty power erupted by the heaven and earth. When fire gathers, it will roar, the mountain will collapse, and the flood dam will turn into an angry dragon. Brother Zai will use this power
It’s called potential energy…”
Wen Ming's voice became smaller and smaller as he spoke, while Gun walked over and patted his head.
"Maybe he is right, but I think you should trust your father more."
"But in thinking and practice, I have stayed in the south for a long time. You may not know [520 www.biquge520.xyz] that I have watched the river for much longer than the river."
"Wen Ming, don't worry, I still have a piece of soil. Even if the embankment is partially damaged, it can be repaired immediately."
There was a small bag hanging on Gun's body, and there was a piece of five-color soil in it.
Wen Ming stared blankly at the five-color soil, and Gun also looked at the soil.
This was something given to him by Di Hong, and he obtained it from Di Hong, the last piece of "breeding soil" in the world.
