What is the concept of a flood of 11 billion to 16 billion cubic meters?

Data estimated based on detailed scientific research by geological experts.

The peak flow rate when the flood broke out was about 480,000 cubic meters per second, which is equivalent to 186 times the current average flow rate of the Yellow River and 500 times the flow rate of the Yellow River section in Qinghai!

You know, the largest recorded flood of the Yellow River occurred in 1843, and the maximum flow was only about 36,000 cubic meters per second!

Such floods that year caused the death of hundreds of thousands of people and left millions homeless!

The Yellow River floods, which were ten times more powerful than this, gathered together and gushed down from Jishi Gorge in an instant!

Such a large-scale super flood peak is enough to flood directly from Jishi Gorge to the lower reaches of the Yellow River 2,000 kilometers away, directly forming a large area of ​​​​Zheguo!

If it were in a feudal society, such an unprecedented flood would be enough to paralyze or even destroy the entire country!

"A flood disaster of this magnitude has never occurred in any historical period for which China has accurate historical data. It is a very rare and huge flood."

"It can even be said to be the largest flood that has occurred on earth in the past 10,000 years!"

Zhang Cheng pushed up his glasses and said with some emotion: "To be honest, when we confirmed the flood, I immediately thought of the prehistoric flood in Chinese legends."

"It was Dayu and his father. The two generations worked together for decades to successfully control the great flood."

"After conducting carbon 14 dating on the bones of young people buried in the Lajia site, we determined that the flood occurred around 1920 BC."

"If, I mean if." Zhang Cheng looked at Kong Wenjian with a searching expression: "What if this flood is really the great flood controlled by Dayu in Chinese legends."

"According to the record that Yu and his father spent about 20 years controlling floods, perhaps the beginning of the Xia Dynasty should be 1900 BC, rather than 2070 BC as given in the Xia, Shang and Zhou dynasty project.

infer?"

As a geologist, Zhang Cheng obviously does not understand how these archaeologists and historians accurately dated the Xia, Shang and Zhou dynasties.

However, he relied on his professionalism in the field of geology and combined it with historical data to come up with a very surprising guess.

At present, most archaeologists and historians accept the dating data provided by the Xia, Shang and Zhou Dating Project.

Zhang Cheng gave an overturning argument and pushed back the starting date of the Xia Dynasty by 170 years.

It is obviously impossible to control such a large flood by human power.

Let alone four thousand years ago, even now, if such a large-scale flood suddenly breaks out in the Yellow River, it will cause the government to be overwhelmed and even mobilize the efforts of the whole country. It will take several years to restore people's livelihood.

However, according to historical legends and historical materials, it took Dayu and his father Gun 20 years to cure the flood.

What happened to Zhang Cheng was that it took almost 20 years for the massive flood discovered at the Lajia site to return to normal.

This is of course not the result of manpower controlling the water, but the self-regulating ability of nature.

Twenty years is enough time for nature to eliminate this major flood crisis.

These kinds of coincidences provide enough evidence for historical legends!

Perhaps the historical truth back then was this.

Four thousand years ago, a huge flood swept across the entire Yellow River Basin.

In China, which was in the period of tribal alliances, there was a tribe named You Chong. This tribe was very good at controlling floods, so they were sent by the leader of the tribal alliance to control the flood.

However, because it was still in the period of a major flood, and with the Chong family in office, it was impossible to control the floods by manpower. It took nine years to control the floods, but no results were achieved.

Until his death and his son took over his flood control task, nine years had passed since the flood broke out, and the flood had also transitioned from the outbreak period to a calm period.

The second generation leader of the Chong family spent another 13 years, exhausting their efforts and energy. At the same time, the flood itself had indeed vented its vents and calmed down.

"Water control" was so successful.

As for these two leaders with Chong clan, the first one is called Gun and the second one is called Yu.

The Chinese tribal alliance at that time was the Three Sovereigns and Five Emperors period in historical legends.

Dayu also relied on his merits and prestige in flood control to take over the leadership position of the tribal alliance from Shun!

There is no legend about the Emperor of Heaven helping to control the floods, nor any messy fantasy events such as Yinglong waiting for Dayu's orders.

In fact, the truth is that it took exactly ten years for the flood to calm down. Even without Dayu, the flood would have naturally disappeared and calmed down.

It just happened that there was such a tribe that took over the task of controlling the floods, so by some mistake, the ancients thought it was Dayu who controlled the floods.

Two hundred years ago in the Qing Dynasty, when there was a flood, I thought it was the Dragon King who was angry.

We can’t expect our ancestors who were still practicing slash-and-burn farming four thousand years ago to understand the principles and geography of floods, right?

Of course, people at that time thought it was Dayu who cured the flood.

Zhang Cheng truthfully stated his guess to Kong Wenjian and Li Chunchao.

Both of them were shocked by his idea.

Is Zhang Cheng’s guess reasonable?

Reasonable, very reasonable!

According to geological research, it can indeed be proven that such a super flood occurred in the Yellow River Basin four thousand years ago.

There is indeed such a flood in Chinese historical legends.

According to legend, Dayu spent 22 years controlling the flood, which was about the same period as this flood.

All kinds of coincidences make it impossible not to believe Zhang Cheng's statement.

However, Li Chunchao still sighed.

"Unfortunately, speculation can only be speculation after all. There is no actual evidence to prove that this prehistoric flood was the flood controlled by Dayu in Chinese legends."

Zhang Cheng could only confirm that such a great flood occurred four thousand years ago and led to the complete destruction of the Lajia site, but there was no evidence linking the flood with Dayu.

"That's not necessarily true." Kong Wenjian, who had been thinking with his head down, suddenly raised his head, looked at Zhang Cheng and asked: "Professor Zhang, you just said that the source of the flood you found 25 kilometers upstream is called Jishi Gorge, right?

?”

"Yeah, what happened to Jishi Gorge?" Zhang Cheng asked doubtfully.

Kong Wenjian looked strange and said almost word for word: "There is such a passage in "Shang Shu Yu Gong"."

"The guide river accumulates stones, as far as Longmen, south to Huayin, east to Zhuzhu, east to Mengjin, east to Luo, Rui, to Daqian, north to Huashui, to the mainland, and north to Jiuhe, the same

Go up the river and into the sea."

"This is a record of the process in which Dayu led his people to cross mountains and rivers and cut rocks to release floods."

"You said that if you were asked to control floods, shouldn't the first stop be from the source of the flood outbreak?"

"The first stop of Dayu's flood control was called "Jishi". Domestic scholars have always believed that "Jishi" here refers to Jishi Mountain at the border between eastern Qinghai Province and Gansu."

"And, if I read it correctly, the location of Jishi Gorge is on the side of Jishi Mountain!"
