Chapter 1472 Generous

On the extremely detailed map, a striking line attracted everyone's attention and surprised everyone.

Zuo Menggeng frowned, checked along the lines, and asked, "Is this a new plan?"

Xue Fengzuo told the truth.

"At the beginning, His Majesty's idea was too difficult for others. After field investigation, we came up with this brand new plan."

Speaking of the Huang control strategy mentioned by Zuo Menggeng at the beginning, everyone present couldn't help but smile.

Even Zuo Menggeng himself blushed, knowing that it was absurd.

"Tell me about your thinking."

Xue Fengzuo returned to seriousness and entered the state.

"At the beginning, His Majesty asked whether it is possible to dig a new river channel in Henan and clean up the original river channel after diverting the Yellow River. But after our field survey, this plan is not feasible."

He drew everyone's attention to the territory of Henan.

"The mountains in the southern part of Henan are continuous. It is too difficult to carry out the construction of the river channel, and it will consume a lot of national power. Moreover, the altitude of these places is slightly higher than the existing river channel, and the river water cannot be diverted at all. There are no ready-made river channels in these places. We have to start from scratch. Even if all the national finances are thrown into it, it will be difficult to do it.”

He first explained the difficulty, which is Zuo Menggeng's idea.

Regarding how to measure the altitude, this is a necessary condition for many engineering constructions.Under the guidance of Zuo Menggeng, the empire has mastered it proficiently.

The method that can be used now is the most primitive geometric leveling method.

Taking the sea surface of Qingdao as the reference point, set up benchmarks every 35 meters, and measure the altitude of each place in turn.

For this reason, the staff of the Department of Geography of the Ministry of Engineering and the Department of Calculation of the Ministry of Intelligence have traveled countless distances over the years, and finally have a slightly more accurate data.

It also provided help for the Yellow River Control Project this time.

After rejecting Zuo Menggeng's idea, Xue Fengzuo began to talk about their more realistic plan.

"After our on-the-spot investigations, the section of the Yellow River on the ground basically originated from Taohuayu in Guangwu. The section from here upwards is not very harmful. Therefore, we believe that new excavations can be made near Taohuayu. The river course is connected to the Weihe River in Weihui, and the Yellow River is diverted to the north by borrowing the course of the Weihe River."

All the central bosses lay down on the map to check the details.

Jiang Wei asked with concern: "Is this idea feasible?"

Xue Fengzuo is full of confidence.

"The Guangwu section is more than 68 meters above sea level, while the Weihui section is about [-] meters above sea level, so it can completely guide the water of the Yellow River there."

People go to high places, and water flows to low places. Everyone understands this simple truth.

Since Guangwu is at a higher altitude than Weihui, and there are plains in the middle, as long as the river channel is dug out, it is enough to turn the Yellow River.

And the next project is not difficult to guess.

It is to widen the channel of the Weihe River, so that the Yellow River flows to the north, and no longer invades the channel of the Huaihe River in the south, so as to completely solve the flood problem of the Huaihe River and Huaihe River.

The two Huaihe Rivers have dense water networks. When the Yellow River came, there was a serious excess of water resources here, so floods occurred frequently.

After changing the course of the Yellow River, it will definitely turn Huaihe River into a land of fish and rice again after treatment.

The key question is, where does the Yellow River go after the diversion?

Zuo Menggeng looked at the map.

"Weihe goes all the way, but it's Linqing. The population is densely populated there, so isn't the construction more difficult?"

Linqing is the place where the empire started. It has not experienced disasters or wars for more than ten years, and many industries and businesses have flourished, resulting in a population of more than 200 million.

If the Yellow River is brought here, it will definitely hurt the empire.

Since Xue Fengzuo dared to come up with a plan, why didn't he have a perfect plan?

"Just borrowing the channel of the Weihe River, it will be diverted here at Daming Mansion, so that the Yellow River will turn northward, merge into the Zhangshui River at Feixiang, and join the Hutuo River after arriving at Wuqiang. As for whether it will continue to flow until Tianjinwei enters the sea, or re- Digging new river channels is an appropriate solution.”

Zuo Menggeng understood, and couldn't help admiring the boldness of the Ministry of Water Resources.

When he decided to change the course of the Yellow River, he strongly rejected the plan for the Yellow River to encroach on the course of the Daqing River.

Because after seeing the situation of the Daqing River on the spot in this era, Zuo Menggeng was really saddened by the disappearance of this river.

In fact, the water volume of the Daqing River itself is very considerable, and now it can be used by boats without the encroachment of the Yellow River, and it has become an important channel connecting Shanghai to the sea.

On the contrary, after the arrival of the Yellow River, the shipping value of this river has been greatly reduced.

The most important thing is that the Shandong Peninsula has an independent water resource system with Mount Tai and Yimeng Mountains as water towers.

The arrival of the Yellow River destroyed the original water resources system of the peninsula, and instead caused frequent water shortages in Shandong in the future.

Therefore, it is inevitable for the Yellow River to divert to the north, but it must not destroy the original water resource system of the Shandong Peninsula.

Although Xue Fengzuo and the Ministry of Water Resources changed Zuo Menggeng's idea, they still strictly abide by it.

So there was this new route of conception.

As for the many puzzles in the new concept, everyone also launched a heated discussion.

"If we go along the course of the Weihe River, it will inevitably have an impact on Linqing and other places. How do you plan to solve this problem?"

Xue Fengzuo replied immediately.

"The difference in the size of the river can be used to make the river diverge in Damingfu, most of it goes north, and a small part flows through Linqing."

He added another sentence.

"The sediment of the Yellow River will definitely have an impact on Linqing and other places, but we have calculated that this impact will still be within a controllable range within a hundred years. Moreover, a sufficient amount of Yellow River water is conducive to supplementing the canal channel and avoiding the north of the canal. blockage."

As soon as he said that, Zuo Menggeng understood.

When the Yellow River diverted, one of the most worrying problems for people was that massive amounts of sediment would cause siltation.

However, siltation is inevitable, but the impact will definitely not be so fast, and it can be improved in the future.

On the contrary, as the shortage of water resources in the north intensifies, the cost of maintaining the normal flow of the canal from Jining to Yanjing has become higher and higher.

With the arrival of the Yellow River, it is a good thing that this section of the canal can be replenished with water.

"Since Tianjin Wei is going to be the provincial capital, my suggestion is that the diverted Yellow River should not encroach on the Wei River (Hai River)."

Zhong Sanlin, who is the governor of Hebei Province, put forward suggestions based on his own interests.

Tianjin Wei is about to become the provincial capital of Hebei Province, and it is also one of the few outlets in Hebei. Of course, he is unwilling to let the Yellow River invade the Weihe River.

Once the sediment accumulation in the port is caused, it will affect shipping.

Moreover, if the Yellow River passes through the city, it will bring endless troubles to Tianjin Wei.

I am afraid that in the years to come, we will have to fight against this river from time to time.

Finding a new estuary for the Yellow River is in the best interest of Hebei Province.
