The first priority is to clean up the blockage, and then we can talk about other ways to deal with it, but ......

Looking at the serious Zhao Hanzhang, Fu Chang said: "Actually, Wang Jing's method is very good, we can build another embankment in this section, and also make a double embankment, which can solve most of the sediment."

He said, "For more than 200 years since Wang Jing, there have been no major floods in the Yellow River."

Zhao Hanzhang frowned, "Such a dam is too expensive and has no benefits."

"Earnings?" Fu Chang frowned and said, "If you can stop the sediment and make the Yellow River free of flooding, isn't this a benefit?"

"But the benefits and the payouts are not equal," Zhao Hanzhang turned his head to look at Fu Tinghan, "What do you think?"

Fu Tinghan knew what she was thinking, and said, "Do you want to build a dam that can store water, divide sand, and use water conservancy?"

Zhao Hanzhang: "Yes, here, in the last canyon of the middle reaches of the Yellow River, there is a large difference in water flow here, and there are many water conservancy projects that can be used."

Fu Tinghan lowered his eyes and said, "It's too difficult, it's not a day's work."

Zhao Hanzhang said, "Let's take our time."

"And what about the urgency?" Fu Tinghan said: "There is only one way to clear and dredge?"

"The problem of the Yellow River, in the final analysis, is still the problem of sediment entering the river," who has attended junior high school and high school geography, who does not know that the fundamental problem is this?

And Zhao Hanzhang also read this kind of books when she was in the library, she clicked on the drawings and said, "To deal with it fundamentally, we have to start from the banks of the Yellow River."

"We are now very convenient because of the years of war and natural disasters, most of the villages on both sides of the Yellow River near the banks of the river are empty, and we can start planning now." Zhao Hanzhang said: "Calculate the safest and most suitable distance for work, and restrict the villages and cultivated land close to the banks of the Yellow River. In addition to planting trees, the imperial court will also contribute an additional amount of money to plant grass and trees on both sides of the Yellow River that can stabilize the soil and water the water."

Fu Chang frowned, and was about to remind her euphemistically, when he heard his eldest brother say slowly, "Sanniang, didn't you say that the treasury was empty? How can you have the money to plant trees? Not to mention whether the trees and grass can stabilize the soil and water and prevent sediment from entering the river, if so, how can you ensure that the money is used effectively?"

Zhao Hanzhang: "Donkey, I have a royal history, a county guard, a county order, and two mailboxes, is there any grass and trees planted on both sides of the riverbank, can I hide from so many people? And I have eyes, and I'll make my rounds."

"As for the money," she said with a wink, she smiled, "the money for the special project doesn't have to come from the treasury, or it can be money that doesn't go into the treasury."

Everyone was stunned, puzzled, "The money that didn't go into the treasury?"

"Yes, the endowments they should pay, donations, or some of the labor they should serve, can be exchanged for planting trees and grass."

Zhao Hanzhang decided to go back and discuss specific practices with Ji Yuan and a few people, such as how many trees each household planted, and how much lawn can be deducted from endowments and donations.

In addition, the uniform land system has been smoothly implemented, after this year's transition, the people should have settled down in the fields, and the new tax law should also be promulgated, starting next year to replace the original land tax system of the Great Jin Dynasty, and change it to rent regulation.

The veterans and remnants of the garrisons in various places should also be released one after another.

Zhao Hanzhang thought a lot for a moment, but quickly got out of his thoughts and continued to discuss water control, "Grass and trees can stabilize the soil and waterproof, this is true, don't believe it and ask Tinghan."

Fu Tinghan nodded, "It's true that we need to plant more grass and trees."

"But the sediment on both sides of the Yellow River is soft and barren, and planting trees may not survive." Fu Chang was previously the county magistrate of Heyin, and he knew this very well, the soil on both sides of the Yellow River was very loose, and as long as it rained, it quickly converged into a stream, and directly rolled up the sediment and rushed into the Yellow River.

That's how so much sediment comes from the Yellow River, and it's hard to plant plants and trees in such soil, maybe they planted it, and soon after a rain, all the plants and trees were washed away.

Fu Tinghan said: "There will always be a way, and in addition to planting plants and trees, you can also try the method of bunching water and washing sand."

This is the Ming Dynasty Ministry of Industry Shangshu Pan Jitao proposed the water control method, and in the Qing Dynasty, Chen Huang improved it, the method of "water and sand flushing" always changed, but the general outline was

It has been like this until modern times, and its effectiveness can be seen.

Different areas use different methods and adapt measures to local conditions, which can not only control river sand, but also save manpower and material resources.

The first time Fu Chang heard of this method, "Beam water and wash the sand?"

"Yes," Fu Tinghan took the pen in his hand and smeared it on the paper, "This method is mainly aimed at the middle and lower reaches of the Yellow River, the Yellow River has accumulated sand for many years, and we don't know how much sediment has been stored at the bottom of the river, we can't dig it out, and we can't send manpower to dig it."

Now it is not modern, there are all kinds of machinery, all rely on manpower, even in the dry season, there is a lot of water in the Yellow River, and it is very dangerous for migrant workers to go down to dredge and dredge.

So they can use other methods to wash away the sediment at the bottom of the river and reduce the loss of manpower.

Fu Tinghan: "Tighten the river channel and use the huge impact of the current to wash out the sediment deposited at the bottom of the river."

When Fu Chang heard this, he approached with interest and asked, "Where are you going?"

"Here," Fu Tinghan drew on the map the near embankment where the water washes the sand, thought about it, and simply drew the remote embankment to prevent flooding, and the lattice embankment used to keep the water and attack the sand also drawn.

Seeing this picture, there was no need for Fu Tinghan to explain, Fu Chang understood at a glance, he stood up happily, and circled in place, "Good method, I never thought of this method, the Yellow River flooded, north to Jizhou, Qingzhou and southern Youzhou, south to Yuzhou, Yanzhou and Xuzhou, but their terrain is different, the method used should also be changed."

"Like the area of Yuzhou, they are all plains, so you should build the dikes you mentioned, but when you go to the Xuzhou area, the terrain is different, and you don't need to build dikes at all, you can also bind water and wash sand, which is much more labor-saving than building dikes." Fu Chang happily turned around, and said to Fu Tinghan excitedly: "Tinghan, you are like your grandfather, you are the person who is most like your father, hahahaha......

Fu Chang finished laughing and looked at Fu Xuan, who had a flat face, and was not very happy, "Big brother, Ting Han is so good, aren't you happy?"

"I'm glad," Fu Xuan said, "I knew he was going to happen early in the morning, after all, he had left my father and princess speechless, and I couldn't."

Fu Chang: "......"

He ignored him, turned his head and looked at Fu Tinghan with a smile, and said, "Tinghan, with your ability, you should go to control the water."

Fu Tinghan said, "Second uncle, I'm just talking on paper, not about controlling the water."

This is still because after the task of water control fell on his shoulders, he tried to recall the relevant knowledge points in the dead of night, but it was really on paper.

Fu Chang didn't think so, he said with a serious face: "Tinghan, don't be arrogant, everyone in our Fu family can control water, your third uncle and fourth uncle didn't learn much from your grandfather, and they are also better than the officials of the Ministry of Water, just look at the water control map a few more times, it's your father, he has no self-motivation, and he can do it at a glance, and you are smarter than us, you are more like your grandfather, how can you?"

Fu Tinghan opened his mouth wide.

Fu Yong and Fu Hong on the side also opened their mouths wide, it was rare for them to see a serious father praising someone like this.

Fu Chang said gently: "You just haven't governed, so you feel like you're just talking on paper, but when you really get to the edge of the Yellow River, you will understand that you can govern, you will."

Even Zhao Hanzhang was persuaded by him, turned his head and looked at Fu Tinghan with sparkling eyes and said, "You go and try it, I think what the second uncle said is very reasonable, maybe you are really talented?"

Fu Tinghan opened his mouth, he couldn't say anything against it for a long time, what should he do, he seemed to have swelled his self-confidence and was convinced.
