Due to the rain for several days, there was also news of an emergency flood control situation in Ningzhou, and Li Yi couldn't stay here.

Li Yi, who was like an arrow, saw that he had the backbone here, and immediately decided to rush back to Ningzhou on the same day to deal with the increasingly serious flood.

Li Yi left Lu Song, Lu Huai and a dozen personal soldiers to Tang Jingtian, and let them be responsible for Tang Jingtian's daily diet and security work, until the Tangdan Inspection Department was completely rebuilt and all the affairs here were on the right track, and then they returned to Ningzhou.

Worried about the flood situation of Panjiang, Li Yi took a large group of personal soldiers, braved the dense drizzle, waded through the muddy and muddy rain, and rushed to Ningzhou non-stop.

Although it was difficult to walk on the road, it only took more than two hours to enter Ningzhou City.

As soon as he entered the Xuanfu Embassy's Mansion, Li Yi smelled a musty smell, which made people feel depressed.

This place in Yunnan has a humid climate, and it has not felt anything since the beginning of this year due to drought. Now that it has been raining for so many days in a row, this dampness is even more unbearable.

Although Li Yihe has not seen each other for more than 20 days, and he is also very worried, the current pressure on flood control in Yunnan is serious, and it is better to deal with flood control affairs first.

Li Yi walked quickly into the conference hall, and everyone in the hall who was working quickly stood up.

In addition to Lin Yi, Lin Jin is also among them. After greeting everyone, he hurriedly asked about the recent flood control situation in Panjiang.

Lin Yi said with a worried face: "The rain has not stopped in the past few days, I went to see it in the morning, and the water level of the Panjiang River has not dropped at all, and it has risen by nearly one meter, and the threat to the embankments on both sides of the river is getting bigger and bigger." ”

"According to our rough statistics, now only the Panjiang embankment near Ningzhou has broken 19 openings, and our officers and soldiers and local people are working hard to block them."

"All the people are not idle, and General Jane has been organizing officers and soldiers to be busy reinforcing the embankment and transporting relief materials while comforting the casualties. And Master Qian couldn't just take care of the waterlogging in Ningzhou City, and he hadn't slept for several days. ”

"The embankment on the river bank is in constant danger, and I, Lord Zheng, and General He frequently inspect both sides of the Panjiang River, but we can only tear down the east wall to make up the west wall, and run back and forth like a fire brigade, and the effect is not very ideal."

However, in the past ten days, Lin has traveled all over the upper and lower reaches of the Panjiang River, and even Luliang County. On the basis of comprehensive investigation and analysis, he put forward a strategy that can thoroughly control the floods. ”

"After General He and I consulted with them, I felt that although it was very difficult, it still made some sense, so I might as well let Lin Jin tell you more!"

Li Yi let out an 'oh', and hurriedly turned his head to look at Lin Jin, before I could ask, Lin Jin couldn't wait to say: "Dashuai, the Panjiang flood has been going on for a long time, but it is more serious this year." I remember when I was a child, the guards on both sides of the Panjiang River broke through several times, and although they did not directly invade Ningzhou, the nearby villages did suffer from it. ”

"This year's rainfall is too much, it has far exceeded previous years, if it rains for a few more days, I'm afraid Ningzhou may be flooded, this is not alarmist!"

Li Yi nodded, and said worriedly: "There are more than 70,000 residents in Ningzhou City and the surrounding villages, and they will be harmed by the Panjiang flood at any time, and now it has reached the most critical time. Yunnan has been plagued by natural disasters this year, and it can no longer be hit by floods in any case. ”

"I think so, your water control strategy is not only to temporarily solve the current threat of flooding, but also to treat both the symptoms and the root causes, if you can manage the Panjiang flood once and for all, it will be even more ideal."

Lin Jin heard Li Yi say this, his expression was slightly hesitant, he lowered his head and pondered for a while, his face showed a look full of confidence, he said with confidence: "Dashuai, this time I have inspected hundreds of miles up and down the Panjiang River, and I have a general understanding of the situation and trend of the river, and it should be said that the harvest is still relatively large." ”

"After on-the-spot investigations, I think we still need to learn from the ancients and take countermeasures according to local conditions in order to receive good results."

"I think that when Dayu controlled the water in ancient times, he adopted the method of 'dredging the river and diverting the tributaries', which finally subdued the unruly flood and allowed the people on both sides of the Yellow River to live and work in peace and contentment. In contrast, the governance of our Panjiang River is much simpler. ”

"In the past few days, I have also figured out some preliminary ideas for controlling the floods of the Panjiang River through the investigation and consideration of the Panjiang waterway and consulting with experienced people in the Panjiang River basin. It can be summed up in twelve words, 'mainly sparse, combined with dredging and blocking, and leading floods into the warehouse.' ’”

Lin Jin paused for a moment, and saw Li Yi nodding frequently with joy on his face, before he continued: "According to the local people, and my own private observations, the terrain of the lower reaches of the Panjiang River has been rising in recent years. ”

"This is partly due to the fact that the sediment washed away by the banks of the dikes over the years, and the continuous siltation and raising of the riverbed. On the other hand, there are also downstream terrain that is too high, and there is a serious lack of flood channels, resulting in no place for flood water to vent, which further aggravates the flood invasion on both sides of the river. ”

"Whatever the cause, how serious the consequences are. As long as we find the right cause, we can prescribe the right medicine and find an effective way to deal with it. ”

"The most important thing about the twelve-character policy I am talking about is the problem of sparseness. Since the river channel is to be dredged, it is necessary to consider the downstream flood capacity. ”

"At present, in the downstream area, because there are only two tributaries of the water, and many places are sandwiched by mountain gorges and high mountains, the upstream river water can only flow to the low-lying plains. In the event of a once-in-a-century flood, floods will wreak havoc in densely populated plain areas, bringing devastating disaster to the local people. ”

"After some exploration, I finally found a natural reservoir area between Wucai Mountain and Niutou Mountain. The length of this natural canyon is about 40 miles long, the width is more than 20 miles, and the depth is enough to be dozens of zhang deep. ”

"We only need to dig a river about 27 miles long from the middle reaches of the Panjiang River to the reservoir area, divert the water of the Panjiang River there, store it into a reservoir, and then build a dam from the outlet of the downstream of the reservoir, which can not only play a role in regulating the water level of the Panjiang River, but also store water here into a reservoir, and solve the problem of drinking water and watering the fields of the people in the dry season, which can be said to be a good thing to kill two birds with one stone."

Wonderful!
