I watched Er Chuang’s short video, and everything went numb!

[In order to solve the sediment problem of the Yellow River, Longguo built two water conservancy projects in Henan: Sanmenxia and Xiaolangdi. 】

[To tell the truth, Sanmenxia is not a very successful dam. 】

[After its completion in 1961, Sanmenxia did solve the problems of flood control, water supply and irrigation downstream, but due to lack of experience, design experts did not realize the contradiction of the Yellow River's water and sediment, that is to say, the Yellow River has "less water and more sand", and the relationship is very uncoordinated. 】

[Three years after the dam was completed, the elevation of Tongguan to the west of Sanmenxia continued to rise, from 323 meters to about 328 meters, and finally threatened the flood of the Weihe, the largest tributary of the Yellow River. 】

[In the event of extreme rainstorm, the river water will be poured into the Guanzhong Plain. 】

......

The plane of Taizong of the Tang Dynasty.

Li Zhi was surprised:

"There are times when the dragon kingdom goes wrong?"

has been in the high-altitude giant screen, all of them have seen the various successes of the Dragon Kingdom in the future, and it is rare to see the Dragon Kingdom in the later generations go wrong in major projects, so Li Zhi was very shocked and surprised.

"If a person is not a sage, he can do no wrong. "

"Especially in something as complex as managing the Yellow River, experience always needs to be accumulated slowly. "

Li Shimin replied calmly.

......

[After discovering the problem of Sanmenxia, China later prepared for the construction of the Xiaolangdi Water Conservancy Project. 】

[Xiaolangdi is more than 100 kilometers away from Sanmenxia, which is a great project and a "trump card" for sediment control. 】

[Xiaolangdi Reservoir covers an area of 272 square kilometers, with a total storage capacity of 12.65 billion cubic meters, which can intercept 7.8 billion tons of sediment from the Yellow River. 】

When the water in the upper reaches of the Yellow River flows down, it first flows into the Xiaolangdi Reservoir, which deposits sediment to reduce the sediment accumulation in the lower reaches of the Yellow River. 】

[Xiaolangdi can not only store water, but also artificially create flood peaks, thereby scouring the middle and lower reaches of the river, the scouring area has reached 2 billion m3, and the depth of the river channel has also reached 2~3 meters, which greatly enhances the sediment retention and flood discharge capacity of the river trough. 】

[During the flood discharge period, the sediment deposited in the riverbed from the Xiaolangdi Reservoir to the estuary of the Yellow River will be washed into the sea by the potential energy of the river. 】

[From late June to early July every year, it is the flood discharge and sediment discharge period of Xiaolangdi Reservoir. 】

[A few days before the sand is discharged, the river will be washed with clean water to make the river cleaner and straighter. After the gate was opened, a large amount of turbid muddy water leaked out, bringing a thousand waves and waves. 】

[Now, every year, tourists come to Xiaolangdi Scenic Area 22 to watch the magnificent scenery of flood discharge and sand discharge. 】

[If you have time, you can also come and take a look, it is indeed very spectacular, this row is not sand, it is hope!]

......

Accompanied by narration subtitles.

In the high-altitude giant screen, a video image of the Xiaolangdi Reservoir during the "flood discharge and sediment discharge" appeared.

The surging water of the Yellow River forms a flood peak, and in the BGM of "defending the Yellow River", it pours down majestically with the momentum of thousands of horses, which is extremely spectacular.

Although it is separated by a giant screen in the sky, many ancients of all dynasties and dynasties are still deeply shocked when they see such a spectacular scene.

"It's spectacular!"

"Stormy waves, turbulent momentum!"

“......"

Many ancients of all dynasties exclaimed.

The plane of Xuanzong of the Tang Dynasty.

Li Bai looked at the rushing Yellow River in the giant screen in the sky, took a sip of wine, and said loudly:

"You don't see, the water of the Yellow River comes up from the sky, rushes to the sea and never returns. "

......

The plane of the Great Ming Taizu.

Zhu Yuanzhang looked at the spectacular scene of "flood discharge and sand discharge", and his eyes were full of envy.

Since the end of the Tang Dynasty, continuous man-made disasters have caused serious damage to the middle and lower reaches of the Yellow River, and the management of the Yellow River has become extremely difficult.

After he established the Ming Dynasty, he continued to invest heavily in the management of the Yellow River floods, but with little success, and the Yellow River was still erratic and frequently breached.

Now from the video of the giant screen in the sky, we know that the key to controlling the Yellow River is to drain the sediment first.

However, the reservoir dam similar to the "Xiaolangdi Water Conservancy Project" of the later Longguo was difficult to build under the conditions of the Ming Dynasty.

"Hey. "

Zhu Yuanzhang sighed in his heart.

This method cannot be learned for the time being, and we can only wait for the industrial revolution to start tomorrow to see if it can be built.

......

[Since 2002, in 22 years, the lower reaches of the Yellow River have been cut down by an average of 3.1 meters, which not only solves the problem of raising the riverbed in the lower reaches of the Yellow River, but also makes the riverbed lower in many places. 】

[Some saline-alkali land in Shandong has become farmland due to the increase of sediment, and the average yield per mu can increase by more than 20%. 】

......

The ancients of all dynasties looked at the green farmland in the giant screen in the sky, both shocked and envious.

"That's amazing!"

"The means of the Dragon Kingdom to govern the Yellow River in the later generations are too strong!"

"Turn waste into treasure!"

“......"

Many ancient people were amazed.

......

[At the beginning of 2022, the Sanmenxia Reservoir also ushered in a "new atmosphere" of sand control. 】

[The "Junhe 007" assembled environmental protection cutter suction dredger developed by Longguo has a length of 45 meters and a width of 8.2 meters, with an average hourly sand pumping flow of 4,500 cubic meters and a monthly sediment removal of 400,000 cubic meters. 】

[The extracted sediment can fill in the surrounding pits, improve the land, and add new farmland.] 】

......

"Shhh

The ancients of all dynasties watched the work demonstration video of "Junhe 007" and were amazed again.

Such a magical machine has completely exceeded their imagination.

They all sighed in their hearts that the dredger of the Dragon Kingdom in the future was too powerful.

And to be able to develop and manufacture such a dredger, the future Dragon Kingdom will undoubtedly be even more powerful!

"The Dragon Kingdom of the Later Generations is really too strong!"

Many ancients sighed in their hearts.

Emperor Wu of the Great Han Dynasty.

Liu Che looked at the "Junhe 007" in the giant screen, and his eyes were full of "want".

If his great man could have this artifact, it would be much easier to govern the Yellow River.

It's not just Liu Che.

In the rest of the dynasties, there were many emperors who had the same idea.

For the "Junhe 007", a sand dredging artifact, they are very greedy.

......

[Downstream sediment and siltation reduction is only a symptom, in order to fundamentally solve the problem, we must start from the middle and upper reaches to reduce soil erosion on the Loess Plateau. 】

Since the founding of the People's Republic of China, China has always regarded the soil and water conservation of the Loess Plateau as the top priority. 】

[From the 50s to the 70s, China experimented and promoted the three prevention and control technologies of "mechanized terraces, damming by water falling, and aerial seeding afforestation". 】

[In the 80s, it entered the stage of comprehensive management of small watersheds, and the governance model of "afforestation on the top of the mountain, returning farmland to grass on the hillside, building terraces on the mountainside, and damming and silting at the bottom of the ditch" was studied through practice. 】

[In the 90s, the prevention and control of soil erosion was fully brought into the rule of law, relevant laws were born, and special departments were established. 】

[After 2000, the prevention and control of soil erosion entered the stage of ecological construction and protection, and various projects such as returning farmland to forest and grassland, closing mountains for greening, and silting dam systems began to be fully constructed. 】

[In this process, I have to mention a great project: the Three-North Shelterbelt. 】

[This large-scale artificial forestry ecological project, which began in 1978, has planted 3,014 hectares of forests, equivalent to the area of three Jiangsu provinces. 】

[It is like a green Great Wall, rejecting eight deserts and four sandy lands in the north, and protecting the Loess Plateau and the North China Plain inside. 】

......

A panoramic shot of the "Three-North Shelter Forest" from the air appeared in the high-altitude giant screen.

"So many trees!"

The ancients of all dynasties were shocked when they looked at the dense forest that could not be seen at a glance.

In the future, the Dragon Kingdom actually planted such a large-scale forest artificially, how much money and time did it take to invest it?

It's incredible!

And starting from the Han plane, the more the ancients in the later dynasty plane, the more shocked they became.

Because the more time passes, the more the vegetation in the hinterland of the Loess Plateau is destroyed.

The Ming Dynasty became the ancestor plane.

Zhu Di said with emotion:

"That's a lot of money!"

By the time of the Ming Dynasty, the vegetation in that part of the Loess Plateau had basically been destroyed, and it was already a large area of bare.

Now that he saw that after the governance of the Dragon Kingdom in later generations, the Loess Plateau became green and verdant, and he was naturally extremely shocked in his heart.

Meanwhile.

He also began to think about learning from the later Dragon Kingdom and promoting large-scale tree planting on the Loess Plateau.

After all, later generations have said that if you want to fundamentally solve the flood of the Yellow River, you must control the soil erosion on the Loess Plateau.

......

[Since 1980, the Loess Plateau has gradually turned green at an annual growth rate of 0.37%, and the vegetation coverage rate has increased in a long-term manner, reaching about 63% so far, with a terraced area of 55,000 square kilometers and 19.4 billion tons of sediment intercepted by silt dams. 】

[The most important thing is that the vegetation has successfully prevented soil erosion. 】

[According to statistics, the area of soil erosion on the Loess Plateau has been reduced by 222,700 square kilometers, equivalent to the area of 48 Qinghai lakes, and the main color of the whole land has changed from yellow to green, which has greatly reduced the amount of sediment transported by the Yellow River. 】

[Over the past few decades, the sediment content of the Yellow River itself has dropped by more than 80%, and it is no longer the world's largest river in terms of sediment content and sediment transport. 】

The barrage flew out: (Read the violent novel, just go to the Feilu Novel Network!)

"And who's number one now?"

"Reply-that's naturally the magical river of the Three Kingdoms. "

"Reply - it turned out to be the Ganges!"

"Reply - very reasonable, haha, the Ganges is more than just a large amount of sand. "

“......"

Many ancients of all dynasties looked at the giant screen in the sky and wondered.

From the barrage sent by those people of the Dragon Kingdom in later generations, they vaguely felt that this river called "Ganges" seemed to be a little special.

......

[Afforestation in the upstream and midstream is finally showing results downstream. 】

[Kaifeng, Henan has suffered from the Yellow River since ancient times, and has broken 338 times since it was recorded, and it was submerged and destroyed 7 times. 】

[Now from the air, the once desolate river beach has become a green corridor, the 88 kilometers of the Yellow River are full of green trees and flowers, watching the gentle and calm Yellow River flow through the embankment, the people of Kaifeng are finally no longer afraid of the Yellow River. 】

......

"The Dragon Kingdom of the Later Generations is amazing!"

The ancients who experienced the Kaifeng flood in the past dynasties sincerely admired it in their hearts.

They are the most aware of the great threat and tragic damage of the Yellow River to Kaifeng. []

In later generations, the Dragon Kingdom was able to completely remove the threat of the Yellow River to Kaifeng, which was definitely a great merit in their hearts.

......

[In the early days of the establishment of the New Dragon Kingdom, the area of deserts, barren mountains and deserts accounted for 4% of the entire land area. 】

[Today, Longguo is the country with the most artificial forests in the world, and the forest coverage rate has increased from 12% in the early 80s of the 20th century to 23.04%. 】

[Since 2000, the green area of Longguo has accounted for 25% of the total green area in the world, and it is the Three-North Shelterbelt and many greening projects that have created this green miracle. 】

Barrage flying:

"It's fun to fight with the sky!"

"Salute to the tree planters!"

“......"

See here.

Many ancients in all dynasties were also extremely emotional.

In order to control the Yellow River, the Dragon Kingdom of later generations did its best.

It was also a great success.

It is indeed admirable.

......

[Sand discharge in the downstream, sand fixation in the middle, and water increase in the upstream, Longguo has established a complete set of water conservancy management system. 】

[Perhaps, in the future, the Yellow River flood problem that has plagued the Chinese dynasties for thousands of years is likely to be cured. 】

[The Yellow River, maybe you can really say goodbye to the river on the ground completely!]

......

Watch this epilogue of the video.

Many ancients in all dynasties were full of emotion.

They hoped that the Dragon Kingdom would one day be able to completely solve the problem of flooding the Yellow River, and at the same time, they also hoped that their dynasty would suffer less from the flooding of the Yellow River.

And for many emperors of all dynasties.

In addition to the shock, from this video, they also learned some experience in managing the Yellow River.

This will also help their respective dynasties to manage the floods of the Yellow River.

......

High in the sky.

Video refresh.

New videos appear.

[How dirty is the Ganges? 4,800 people are poisoned every day, and the water of the Ganges River is endangering the world!]

See the title of this video in the giant screen in the sky.

The ancients of all dynasties were shocked instantly.

They had just learned the name of the Ganges from the previous video, and they thought it was a bit strange for later generations to mention it.

Now I finally know why.

It turns out that this is a poisonous river!

4,800 people are poisoned every day, which is simply terrible!

At the same time as the shock.

The ancients also took a keen interest in the content of the following video, 910.

They want to know, what is going on with this Ganges River of the Three Kingdoms?

......

[The whole world knows that the Ganges is thrillingly dirty. 】

[But including the netizens of the Dragon Kingdom, the photos and videos of the world, and the image of the Ganges River that is well known to various media and self-media are actually a small section of the river in Varanasi, the holy city of the Three Kingdoms. 】

[The total length of the Ganges River reaches 2,525 kilometers, and it is only a small section here.] 】

So the Ganges is demonized. 】

[I would like to say to be fair and responsible, this is not the case with the Ganges beyond Wallarasi, and with its many tributaries. 】

[They, they may be dirtier.] 】

Barrage flying:

"Ahh

"I was ready to be rigorous, but suddenly Bengbu stopped. "

"I knew it!"

I smiled with sudden relief. "

“......"

Many ancients in all dynasties were also stunned by such a sudden turn of events.

They also thought that the next thing was to defend the Ganges.

I didn't expect it to be a heavier blow.

"It is very interesting for this person of the Hereafter to speak. "

On the plane of Taizong of the Tang Dynasty, Li Shimin said with a smile.

......

[Moreover. 】

[I also want to say a responsible and fair word: you don't know the Ganges, but the Ganges may know you better than you think. 】

[Did you know that on the banks of the Ganges River, there is the first super super super city of mankind with a population of 200 million?]

[Did you know that 5 billion liters of domestic sewage and 1 billion liters of industrial wastewater are discharged into the Ganges every day?]

[Did you know that in India, 4,800 people die every day from water-borne diseases transmitted by drinking or coming into contact with contaminated water?]

[Did you know that on the banks of the Ganges in one place in Varanasi alone, 32,000 corpses are burned every year, and then the ashes are put into the river?]

[Did you know that the Ganges River has bred a monster that can set human society back 100 years?]

[Do you know why the water is so dirty, and the people of the Three Kingdoms still have to take a bath and drink their fills at the same time?]

[However, I want to wash in the Ganges the most, and it is estimated that it is not those believers, but the dollars that the governments of the three countries claim to use to govern the Ganges, do you know how much it is?]

[If you don't care about any of these issues.] 】

[Then I tell you that the dirty Ganges River will endanger you living in the Dragon Kingdom, so what will you think?]

Barrage flying:

"Although I don't know it very clearly, when I think of it as a Sanguo, I think it is very reasonable. "

"This is the famous Ganges, and it is not unusual for anything strange to happen. "

"If you don't understand, just ask, what does the Ganges have to do with us?"

"Reply - I don't know, ask the same question. "

“......"

The ancients of all dynasties were stunned when they saw so many problems.

This Ganges River in the Three Kingdoms of Ah Sanguo sounds a bit outrageous.

What kind of river is this?

Why would this foreign river endanger the Dragon Kingdom?

The hearts of the ancients of all dynasties were very curious.
