On the extremely detailed map, a striking line attracted everyone's attention and shocked everyone.
Zuo Mengeng frowned, looked along the lines, and asked, "Is this a new plan?"
Xue Fengzuo told the truth.
"His Majesty's original idea was too overwhelming. After on-site inspection, we came up with this brand new plan."
Speaking of the anti-pornography strategy mentioned by Zuo Mengeng, everyone here smiled.
Even Zuo Mengeng himself blushed, knowing it was a bit ridiculous.
"Tell me your thoughts."
Xue Fengzuo returned to seriousness and entered the state.
"At the beginning, His Majesty asked whether it would be possible to dig a new river channel in Henan and clean up the original river channel after diverting the Yellow River. However, after our on-site survey, this plan was not feasible."
He drew everyone's attention to Henan.
"The southern part of Henan has mountains and rivers. Construction of river channels is too difficult and extremely costly for the country. Moreover, the altitude of these places is slightly higher than the existing river channels, and the river water cannot be diverted at all. There are no ready-made river channels in these places. If construction is carried out,
We have to start from scratch. Even if we throw all the national finance into it, it will be difficult to do it."
He first explained the difficulty, which was Zuo Mengeng’s idea.
Regarding how to measure altitude, this is a necessary condition for the construction of many projects. Under the guidance of Zuo Menggeng, the Empire has mastered it.
The method that can be used now is the most primitive geometric leveling method.
Taking Qingdao's sea surface as the reference point, benchmarks are set up every 35 meters to calculate the altitude of various places in sequence.
To this end, the staff of the Geography Department of the Ministry of Engineering and the Measurement Department of the Ministry of Intelligence have traveled countless distances over the years, and finally mastered somewhat accurate data.
It also provided help for this yellowing control project.
After rejecting Zuo Mengeng's idea, Xue Fengzuo began to describe their more realistic plan.
"After our on-site investigation, we found that the upper reaches of the Yellow River basically originate from Taohua Valley in Guangwu. The upper reaches from here are not very harmful. Therefore, we believe that new rivers can be dug from near Taohua Valley.
The river course is connected to the Wei River in Weihui, and the Wei River course is used to divert the Yellow River to the north."
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 90 meters above sea level, while the Weihui section is about 68 meters above sea level. It can completely guide the Yellow River water there."
When people go to higher places, water flows to lower places. Everyone still understands this simple truth.
Since Guangwu is higher than Weihui and there are plains in the middle, as long as the river channel is dug out, it will be enough to divert the Yellow River.
And the next project is not difficult to guess.
It is to widen the Wei River channel so that the Yellow River water flows to the north and no longer goes south to encroach on the Huai River channel, thus completely solving the flood problem in the two Huaihe Rivers.
The Huaihe River has a dense water network, but the arrival of the Yellow River has caused a serious excess of water resources here, resulting in frequent floods.
After changing the course of the Yellow River and then regulating it, the Huaihe River and Huaihe River can be transformed back into a land of plenty.
The key question is, where will the Yellow River go after the diversion?
Zuo Mengeng looks at the map.
"All the way across Weihe River is Linqing. The population over there is densely populated, so wouldn't it be more difficult to construct?"
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 prospered and developed, resulting in a population of more than two million.
If the Yellow River is diverted here, it will definitely be a strain on the empire.
Since Xue Fengzuo dared to come up with a plan, why didn't he have a complete plan?
"Just borrowing the Wei River channel, it will be diverted here in Damingfu, causing the Yellow River to turn northward, merge into Zhangshui in Feixiang, and merge with Hutuo River in Wuqiang. As for whether it will flow all the way to Tianjin Wei and enter the sea, or it will flow again.
Digging new river channels is a suitable solution."
Zuo Mengeng understood and couldn't help but admire the boldness of the Ministry of Water Resources.
When he first decided to change the course of the Yellow River, he strongly rejected the plan for the Yellow River to encroach on the Daqing River.
Because after seeing the condition of the Daqing River in this era, Zuo Mengeng was really saddened by the disappearance of this river.
In fact, the water volume of the Daqing River itself is very considerable. Nowadays, boats can be used without encroachment by the Yellow River, and it has become an important waterway connecting Xanadu to the sea.
On the contrary, after the arrival of the Yellow River, the shipping value of this river was 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 peninsula's original water resources system, which in turn caused frequent water shortages in Shandong in the future.
Therefore, it is inevitable for the Yellow River to change its course to the north, but it must not destroy the original water resources system of the Shandong Peninsula.
Although Xue Fengzuo and the Ministry of Water Resources changed Zuo Menggeng's idea, they still strictly adhered to it in this regard.
Hence this newly conceived route.
Everyone also had a heated discussion about the many confusions in the new concept.
"If we follow the Weihe River, it will inevitably have an impact on Linqing and other places. How do you plan to solve this problem?"
Xue Fengzuo answered immediately.
"The different sizes of river channels can be used to make the river water split in Damingfu, with most of it going north and a small part flowing through Linqing."
He added another sentence.
"The sediment in 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. And a sufficient amount of Yellow River water will help replenish the canal channel and prevent the north of the canal from flowing.
Blockage."
When he said this, Zuo Mengeng understood.
When the Yellow River changes its course, one of the biggest concerns people have is that massive amounts of sediment will cause siltation.
However, siltation is inevitable, but the impact will never be that 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 increasingly high.
With the arrival of the Yellow River, it would be a good thing for this section of the canal to be supplied with water.
"Since Tianjin Wei is to be the provincial capital, my suggestion is that the rerouted Yellow River should not encroach on the Wei River (Hai River)."
Zhong Sanlin, who is the Hebei provincial government official, put forward suggestions based on his own interests.
Tianjin Wei was about to become the provincial capital of Hebei Province, and it was also one of the few outlets in Hebei Province. Of course, he was not willing to let the Yellow River encroach on the Wei River channel.
Once sediment accumulates in the port, shipping will be affected.
Moreover, if the Yellow River passes through the city, it will bring endless trouble to Tianjin Wei.
I am afraid that in the years to come, I 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.
I solemnly declare: I am not an expert in geography or water conservancy. I checked the relevant information online and have not seen it in person. If anyone wants to argue, they can only say: You are right, cough cough.
