Riverside Police.

The news that "Linghai Port" will be moved back to the end of the Yangtze River spread quickly.

The leaders of the three nearby counties came upon hearing the news and asked what day they planned to leave and how to get there, so that they could organize a farewell.I would also like to know how to hand over the large number of emergency supplies left behind after the "Linghai Port" returned to Linghai.

The emergency rescue is over, and people will need disaster relief next, so there is a great demand for supplies. It is reasonable to say that all the remaining supplies should be given to others, but the supplies are not bought by the "Linghai Development Management Committee". Lao Ge and Lao Wang It doesn't count, so I can only call Huang Yuanchang in front of them.

Huang Yuanchang can't be the master either, because the ownership of these materials was handed over to Jingzhou Fangzhi this morning.

How to distribute it is decided by the city leaders.

Lao Ge took this opportunity to briefly talk to Huang Yuanchang about his return plan.

Considering that many leaders of higher-level units did not sign and seal the rescue project materials, Lao Ge decided to take the materials to Jingzhou early tomorrow morning, and asked Huang Yuanchang to help find the relevant leaders. Invite Huang Yuanchang to go to Hanwu together...

The Long Navigation Bureau also needed this set of valuable emergency engineering materials, and Huang Yuanchang readily agreed.

The leaders in Jingzhou City are easy to find, but the big leaders in Hanwu are hard to find. Huang Yuanchang weighed it and decided to call Yuan Bureau to report first.

"Must be signed and stamped by Beihu Fangzhi?"

"Please sign by the director of the Defense Office, or stamp it with the Defense Office."

Huang Yuanchang was worried that the director would think this was formalism, so he thought about it and said: "Juan Yuan, I have read those materials. They are very detailed and professional. It can be said that they are true records throughout the entire emergency construction process. It is very important for future flood fighting and emergency rescue as well as water conservancy projects. Construction has a strong guiding significance and reference value."

The Yangtze River Committee has a hydrological bureau, and there are so many hydrological stations under the hydrological bureau. After decades of daily monitoring and forecasting, they have accumulated very comprehensive hydrological data.

In contrast, the information on water conservancy construction on both sides of the Yangtze River is not so comprehensive, and even a bit messy.

Because the Yangtze River dikes are repaired every year, the state allocates funds for repairs, the province allocates funds for repairs, and cities, counties, towns, and even villages are repairing them.

Coupled with the changing times and changing times, the positions of many dike sections have changed countless times.

For example, the Linghai Reserve Battalion, in which the CSC System holds half of the shares, encountered a dangerous pit collapse some time ago. During the rescue process, a river culvert was dug from under the main embankment of the Yangtze River!

This is a major security risk, and the local government is actually ignorant of it.

Just as Yuan Ju was thinking that this set of materials was indeed valuable, Huang Yuanchang said while the iron was hot: "Moreover...and this set of materials is very meaningful to the Linghai Reserve Battalion. Binjiang knows that they are here to fight the flood. How did they fight the flood? Whether you have achieved some results in the end, you can't just talk in plain language, you must have evidence."

"Understood, I'll help you get in touch with the Provincial Defense Command."

"The old director of the Linghai Transportation Bureau plans to go to Hanwu tomorrow."

"In such a hurry?"

"The big troops will return in a few days. Their feelings are understandable, and Ge Ju has one more thing to do when he goes to Hanwu tomorrow."

Yuan Ju asked curiously, "What's the matter?"

Ge Ju is as scheming as it is fake, Huang Yuanchang felt that he should learn more from Lao Ge in the future, so he couldn't help laughing: "The officers and soldiers in the battalion used to come by car. Now that the rescue mission is completed, Ge Ju considers that many officers and soldiers did not come. I have never been to Hanwu and have never taken a train. It is suggested that the officers and soldiers come to Hanwu by car first, see the Yellow Crane Tower and the Yangtze River Bridge, and then organize the officers and soldiers to take the train back.”

"This suggestion is very good. For example, if you are on a business trip to the capital, you still have to go to Tiananmen Square to take a picture or take a picture."

"So tomorrow Geju will go to the military representative stationed at the train station to buy a ticket."

"Can the military representative help him with this?"

"Tickets are easy to buy, Division 404 will help you get in touch."

"I almost forgot that the reserve forces are also troops, and they are now managed by a higher-level unit."

Lao Ge’s ulterior motives were not about drinking. He suggested that the officers and soldiers go back by train, not just for the entire battalion to come to Hanwu to see the world. It can be said that he intends to let the people of Hanwu see the world!

Huang Yuanchang suppressed a smile, and continued: "Juan Yuan, the problem now is that the Linghai Reserve Battalion has both onshore construction teams and waterworkers. If you want to say that they have made contributions, everyone has made contributions, and you can't just bring onshore emergency construction. The personnel who come to Hanwu, let the personnel working on the water go back like this."

Yuan Ju didn't know why, so he subconsciously asked, "What's their plan?"

"They plan to have the fleet anchor at a wharf in Hanwu for a day, let the comrades on board go ashore, and go to see the Yellow Crane Tower and the Yangtze River Bridge with the comrades on the shore."

"Let the fleet anchor in Hanwu for a day, hahaha, I understand."

"Yuan Bureau, do you know?"

"When they came, they had already been on the upper reaches of the river once. It is said that there was quite a commotion. The Management Committee of China Linghai Economic and Technological Development Zone, the Headquarters of China Linghai Port Project... the two pieces that your old unit sold to them This barge has almost become their mobile advertising boat in Linghai!"

"Thinking about it is a bit ostentatious."

"They're not ostentatious, they're ostentatious!"

"Juan Yuan, since it is too ostentatious, I will tell them that there are not so many docks for them to berth, do their work, and let them go back early."

"In light of major dangers, they rescued two of them. They have indeed made a great contribution. Isn't it just an advertisement, let them do it."

Huang Yuan often asked with a smile: "Really let them show off?"

Yuan Ju said without hesitation: "They own half of our shares, and they recruited our shakers. They live in other people's markets. Why don't they let them go? As for which pier to berth, I will arrange it."

Is this right? Although the Long-distance Navigation Bureau is in Hanwu, it is a different matter from Hanwu.

Huang Yuanchang couldn't help asking: "Juan Yuan, which pier do you plan to let the fleet berth?"

Yuan Ju smiled and said, "They want to see the Yellow Crane Tower and the Yangtze River Bridge, so let them berth at the Yellow Crane Tower Wharf!"

"Yuan Bureau, if you arrange this way, comrades will be very happy and excited if they find out!"

"Not only do we have to arrange berths for the Kaixuan fleet, but we also have to arrange board and lodging for the entire battalion. I was too busy a while ago, so I didn't bother to visit Jingzhou. Changhang Hotel, hold a celebration banquet, and I will attend together with the persons in charge of the Harbor Supervision Bureau, Waterway Bureau, Changhang Public Security Bureau, and Communications Bureau."

"Thank you Bureau Yuan..."

"There is nothing to be thankful for. There are so many officers and soldiers of our long-haul system in the battalion. We should go to toast our comrades."

The achievements of the Linghai Reserve Battalion are also the achievements of the Changhang system!
Ju Yuan was delighted from the bottom of his heart, he thought about it and asked with a smile: "Xiao Huang, who thought of making emergency engineering materials?"

"Ge Ju is Ge Weidong, the old director of the Linghai Transportation Bureau."

"The local transportation system is also a transportation system. I didn't expect our transportation system to have such enthusiastic and responsible old comrades."

"Yuan Bureau, Comrade Ge Weidong is not just enthusiastic, he is responsible for his work for a reason."

Yuan Ju asked with interest: "What's the reason?"

Huang Yuanchang briefly introduced the relationship between Xia Laoge and Sister Wei, especially the relationship with Xianyu, Xiaoyu and others, and added, "I didn't know at first, but later I realized that they played a huge role in this emergency rescue." The Linghai Road and Bridge Company was founded by Comrade Ge Weidong when he was the director of transportation. Hao Qiusheng, the general manager of the Road and Bridge Company, was a cadre trained by him, and the cadres and employees of the Road and Bridge Company are also his old subordinates.”

Yuan Ju was very surprised, and pondered: "So it's not just his whole family that came!"

"Yes, the Road and Bridge Company he founded and the old subordinates of the Road and Bridge Company have also come."

Thinking of what Yuan Ju mentioned just now that the local transportation system is also a transportation system, Huang Yuan often said while the iron was hot: "The water equipment and personnel of the Linghai Reserve Battalion mainly come from our long-distance navigation system, and the shore equipment and personnel mainly come from the local transportation system. Comrade Han Yu was sold to Linghai by our long-term aviation system, so it can be said that the Linghai Reserve Battalion is the reserve battalion of our transportation system!"

Yuan Ju's eyes lit up: "Xiao Huang, why didn't you report such an important situation earlier?"

"Juan Yuan, I'm reviewing, mainly because I've been too busy during this time, so I haven't taken care of it."

"I can't completely blame you. In fact, these situations have been reported in the materials reported by the Harbor Supervision Bureau, Waterway Bureau, and Changhang Public Security Bureau. It can be said that we are fans of the authorities."

Yuan Ju smiled, and continued: "It's not too late to react now, I'll let the office contact the "China Communications News" and notify the "Yangtze River Shipping News" by the way."

……

As night fell, the safety zone built by the Linghai Reserve Battalion was crowded with people and brightly lit.

In a few days, we will be disbanding. Not only will we have extra meals tonight, but we will also have a get-together.

Several platoon leaders of the 132nd Battalion of the 2nd Regiment stood in front of the soldiers, waving their arms, and were busy singing with the old squad leaders of the Linghai Reserve Battalion.

"Search and Rescue Company, come on, come on, come on! We invite you to patter, clap, sweep, sweep, come on, come on!"

"Search and rescue team, come one!"

"Come one, search and rescue company!"

"I told you to sing, but if you didn't sing, you'd be so cowardly..."

The stinky boys of the 2nd Battalion were in high spirits, singing and shouting at the top of their voices.

Ma Jintao, the company commander of the water search and rescue company, was having a meeting on the barge, and the instructor Chen Youren was in charge of the singing scene.

Chen Youren was a cadre who had just transferred to the Changhang branch last year. How could he let a group of recruits beat him when it came to pulling songs? He immediately stood up and shouted: "The east wind is blowing, and the drums are beating! If you want to pull songs, who is afraid of whom?"

"Okay, Chi Chi Chi Chi!"

"There are three companies, all of us soldiers, get ready!"

"What's the difference between us soldiers. It's just because we all wear plain military uniforms. What's the difference between us soldiers. Ever since we left our hometown, it's hard to see our parents! It's different, but it's actually the same. Same, they are all young, they are all passionate..."

Chen Youren tapped the time, and his loud singing echoed by the river again.

After the water search and rescue sang, there was another round of warm applause.

A platoon leader of the 132nd Battalion of the 2nd Regiment turned his finger on the health room, pointed at Liang Xiaojun and Han Xiangmeng who were laughing, and shouted: "Do not lose heart, Doctor Liang, and don't lose heart, Doctor Han. What you pull is spirit, and what pulls you is friendship. Don't care about winning or losing, the first thing is to pull out your feelings!"

The stinky boys in the camp echoed in unison: "It's number one!"

"We can't sing you well. There are only a few people in our clinic. You recruits are bullying!" Han Xiangmeng got up and pointed at them and scolded with a smile.

"Doctor Han, you can sing solo!"

"Comrades, do you want to invite Dr. Han to have a female solo?"

"want!"

"Then what are you waiting for, Chi Chi Chi Chi!"

……

Maybe after staying on the water for a long time, Han Yu doesn't like excitement and prefers quiet.

But not participating in the La Song tonight is not because I don’t like too much excitement, but to prepare for the withdrawal and the possibility of another flood.

Don't look at Jingzhou for so many days, and have rescued so many dangerous situations, but they are all like "firefighters". I can't even figure out the north, south, east, and west.

Worker Xi, who knows the situation best here, came, and Han Yu naturally wouldn't miss this opportunity. After dinner, he asked Worker Xi to give a good talk to the cadres above the sub-team leader.

As a senior expert of the Linghai Reserve Battalion, Mr. Xi couldn't just enjoy the treatment of an expert and do nothing. Not only did he agree straight away, but he also spoke very seriously.

"Thousands of miles of the Yangtze River are dangerous in Jingjiang. This is the consensus formed in the flood control of the Yangtze River for many years. But why is Jingjiang dangerous, and where is the danger?"

Mr. Xi put down his chalk and pointed to the water map he had just drawn on the blackboard: "First of all, let's start with the geographical location of Jingjiang. The section of Jingjiang starts from Zhicheng and goes down to Chenglingji. It is about 347 kilometers long. Chikou is the boundary and is divided into Upper Jingjiang and Lower Jingjiang.

The terrain on both sides of the Jingjiang River is high in the south and low in the north. Due to years of flood diversion and sediment deposition, the terrain on the south bank is several meters higher than that on the north bank.Historically, most of the north bank was an alluvial plain formed after the disintegration of Yunmengze. The river network intersects and there are many lakes.

Once breached, the Jianghan Plain in Jingbei Yimapingchuan will be flooded, and even directly threaten Hanwu.In order to resist the raging flood, since 345 AD, after more than 1600 years of continuous construction, the Jingjiang Levee, which is now about 182 kilometers long, was built from Zaolingang, Jingzhou, the most dangerous place on the north bank, to the south of Jianli City.

The Jingjiang embankment has built an important flood control barrier for the Jianghan Plain, directly protecting Jingzhou City, Lingjiang County, Jianli County, Honghu City, Jiangqian City, Taoxian City, and Hanchuan City to the north of the Jingjiang River and south of the Han River. Part of the plain lake area and the 1100 million mu of arable land within the Jiangbei area of ​​Hanwu City, the safety of the lives and properties of more than 1000 million people and economic and social development! "

I used to think that the national, provincial, and municipal levels were a little bit biased in terms of water conservancy construction. The Jiangbei embankment was better repaired, and the embankment standard on the Angong side was far inferior to that of Jiangbei. It turned out that the Jingjiang embankment in Jiangbei was so important.

Everyone reacted and took notes with their pens.

"Secondly, the flood discharge capacity of the Jingjiang river course is limited. The current Jingjiang embankment has only a once-in-ten-year flood control capacity, and even if the Jingjiang flood diversion project is activated, it will only have a flood control capacity of about a once-in-20-year flood."

Mr. Xi took a deep breath and pointed at the blackboard again: "The maximum safe flood discharge of the Jingjiang River section, this flood discharge includes the flood discharge after the diversion of the four outlets in Jingnan, which is about 60000 cubic meters per second. According to the historical flood survey of more than 860 years , the upstream Changyi flood peak flow greater than 80000 cubic meters occurred 8 times per second.

其中大于90000立方米每秒就发生过5次，尤其是1860年和1870年两次特大洪水，洪峰流量分别高达100000立方米每秒和105000立方米每秒。1870年长江上游洪水还与清江洪水相遇，导致枝城洪峰流量居然高达110000立方米每秒，可见上游巨大的洪水来量与荊江河道的安全泄洪量差距有多大。”

Sun Youyi was originally an engineering expert, but now he has become a half-flood control expert. He raised his hand and asked, "Xi Gong, which four are the four in Jingnan?"

"That's a very good question. This is what I'm going to talk about about the complicated river-lake relationship in the Jingjiang River."

Pointing to the water area map on the blackboard, Mr. Xi said solemnly: "The water from the upper reaches flows out of the Three Gorges, flows through Changyi and Zhicheng, and then enters the Jingjiang section with flat terrain, gentle riverbed slope, and curved river course. There is the Juzhang River confluence on the north bank. The entrance and exit are located about 20 kilometers upstream of the Shashi hydrological station.

The floods of the Juzhang River mostly occur in July and August each year, which coincides with the main flood season of the Yangtze River. They often encounter the floods of the Yangtze River and can raise the water level of Shashi by 0.1 to 0.2 meters.

There are Songzikou, Taipingkou, Ouchikou, and Tuixiankou on the south bank. Among them, Tuixiankou has been controlled by gates built in 1959, and there are actually only three natural diversions.

The water from the upper reaches flows into Dongting Lake through these four mouths, and joins with the water from the Hunan, Zi, Yuan, Li and other small and medium-sized rivers around the lake area.After being stored in Dongting Lake, it flows into the Yangtze River from Chenglingji, which can reduce the amount of flood discharge in the Jingjiang River and relieve the pressure of floods on the Jingjiang embankment. "

"But on the other hand, the large amount of sediment carried by the floods flowing into the lake area caused the siltation and shrinkage of Dongting Lake. Coupled with the artificial reclamation of the lake, the volume of Dongting Lake has decreased by more than 100 billion cubic meters in the past 100 years. At the same time, the four flood channels are also year by year. The high siltation has led to a decrease in the amount of water flowing into the lake from the four mouths of the Jingjiang River, and the ability of Dongting Lake to regulate and store the Jingjiang flood has been weakened year by year."

"Especially when the floods of small and medium-sized rivers around the Dongting Lake area collide with the Jingjiang floods, congestion will be formed at the exit of Chenglingji and the water level will be raised. In the water level, the danger will increase sharply. Therefore, the impact of the relationship between the rivers and lakes on Jingjiang's flood control is very significant..."

If you don't know the hydrological conditions, how can you prevent floods?

Everyone benefited a lot, and they were listening intently, when Old Han hurriedly pushed the door open and walked in.

Xi Gong subconsciously asked: "Han Gong, what's wrong?"

Lao Han held up the mobile phone that Lao Ge was given in the afternoon, and said solemnly: "The colleague from the Hanwu Meteorological Bureau just called me. A cumulonimbus cloud has risen near Yingwu Island in Hanwu, and it is rapidly expanding like popcorn. !"

"The two air currents you mentioned this afternoon met over Hanwu?"

"I still do not know yet."

Lao Han raised his arm and looked at his watch, and added: "The weather satellite will pass over Hanwu at around [-]:[-] tomorrow morning, and we will not receive the space observation results until [-]:[-] tomorrow morning."

Aren't your predictions always inaccurate?

Can it be maintained as always!
Han Yu suddenly felt that it was not good for the father-in-law's prediction to be too accurate, so he couldn't help asking, "Dad, will it rain in Hanwu?"

Lao Han took a few deep breaths and said worriedly: "Hanwu is more than 200 kilometers away from us, and my radar can barely observe it. From the observation results just now, the humid air is stirring over Hanwu and has climbed sharply. After more than ten kilometers, the huge amount of water vapor will turn into a torrential rain."

Han Yu asked, "How long will it take?"

"I don't have much data, so I can't say for sure how long it will take. But one thing is certain, as the airflow rises, low pressure will form on the ground, which will attract more humid airflow, and the heavy rain will be heavy. Maybe it will be out of control!"

"What about our side?"

"There are no cumulonimbus clouds over us for the time being, and there should be no rain tomorrow morning. The climate is changing too fast, and it will be hard to say tomorrow afternoon."

The water level of the Jingjiang River has dropped, but not fast enough.

Mr. Xi just said that the reason why the water level in Jingjiang is so high is because of the poor drainage due to the influence of upward pressure and downward pressure.If there is a sudden heavy rain in Hanwu, and the amount of rainfall is heavy, it will definitely raise the water level of Jingjiang!

Although Lao Zhangren's 771 radar is an antique, its main function is to detect rain, otherwise it would not be called a rain detection radar. He said that it will rain in Hanwu, and it will rain in all likelihood.

Han Yu realized the seriousness of the problem, looked back at the crowd and smiled wryly, "Guys, maybe we won't be able to go back for a while."
