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

After hearing the news, the leaders of the three nearby counties came and asked when and how they planned to leave so that they could organize a farewell. I would also like to know how the large amount of emergency supplies left behind by "Linghai Port" will be handed over after it returns to Linghai.

The emergency rescue is over, and people need to provide disaster relief next. There is a huge demand for supplies. Logically speaking, the remaining supplies should be given to others, but the supplies were not bought by the "Linghai Development Management Committee". Lao Ge and Lao Wang No matter what he said, he could only call Huang Yuanchang in front of them.

Huang Yuanchang also couldn't make the decision, because the ownership of these materials was handed over to Jingzhou City Fangzhi this morning.

How to allocate 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 stamp the rescue project documents, Lao Ge decided to take the documents to Jingzhou early tomorrow morning and asked Huang Yuanchang to help find the relevant leaders. He would wait until the Jingzhou side was signed and stamped before proceeding. Please invite Huang Yuanchang to go to Hanwu together...

The China Shipping Bureau also needed this valuable set of rescue engineering information, and Huang Yuanchang agreed.

The leaders of Jingzhou City were easy to find, but the big leaders of Hanwu City were difficult to find. Huang Yuanchang weighed the situation and decided to call Bureau Yuan to report first.

"Does Beihu Fangzhi have to sign and seal it?"

"Please ask the director of the Defense Office to sign it, or stamp it with the seal of the Defense Office."

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

The Yangtze River Commission has a Hydrological Bureau, which has so many hydrological stations. After decades of continuous forecasting and reporting, it has accumulated very complete hydrological data.

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

Because the Yangtze River embankments 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 vicissitudes of life, the positions of many embankment sections have changed countless times.

For example, the Linghai Reserve Battalion, which holds half of the shares of Changhang Navigation System, encountered a danger of a cave collapse some time ago. During the rescue process, a culvert leading to the Yangtze River was dug out from under the main embankment of the Yangtze River!

This is a major safety hazard and the local government knows nothing about it.

Bureau Yuan was thinking that this set of information was indeed valuable. Huang Yuanchang struck while the iron was hot and said: "And... and this set of information is very meaningful to the Linghai Reserve Battalion. Everyone in Binjiang knows that they came to fight the flood. How did they fight the flood? Whether you have achieved something or not, you can’t just talk in vain, you must have proof.”

"I know, I'll help you contact the Ministry of Defense."

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

"So urgent?"

"The large army will return in a few days. Their mood is understandable, and Ge Jue has one more thing to do when he goes to Hanwu tomorrow."

Bureau Yuan asked curiously: "What's the matter?"

Ge Bureau is a scheming and scheming person. Huang Yuanchang felt that he should learn more from Lao Ge in the future. He couldn't help but smile: "The officers and soldiers in the camp came by car before. Now that the rescue mission is completed, Ge Bureau considered that many officers and soldiers did not come. I have never taken a train before going to Hanwu, so I suggest 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 is a good suggestion. For example, if you go on a business trip to the capital, you might want to go to Tiananmen Square to take photos or leave a photo."

"So Mr. Ge will go to the military representative stationed at the train station tomorrow to buy tickets."

"Can the military representative do this for him?"

"The tickets are easy to buy, and the 404th Division will help contact you."

"I almost forgot, reserve forces are also troops, and they are now managed by superior units."

Lao Ge's drunkenness was not about drinking. He suggested that the officers and soldiers take the train back. It was not just as simple as letting the entire battalion of officers and soldiers come to Hanwu to see the world. It can be said that he planned to let the people of Hanwu see the world!

Huang Yuanchang suppressed his laughter and continued: "Director Yuan, the problem now is that the Linghai Reserve Battalion has both shore construction teams and water workers. When it comes to making a contribution, everyone has made a contribution. We can't just lead the shore rescue construction team. The personnel came to Hanwu and let the personnel working on the water go back."

Bureau Yuan didn't know why and subconsciously asked: "What are they planning?"

"They plan to let the fleet anchor at a pier in Hanwu for a day, and let all the comrades on board go ashore 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."

"Bureau Yuan, do you know?"

"They had already swam up the river once when they came. It was said that the noise was quite loud. China Linghai Economic and Technological Development Zone Management Committee, China Linghai Port Engineering Project Headquarters...the two that your old unit sold to them This barge has almost become their mobile advertising boat in Linghai!"

"It's a bit ostentatious when you think about it."

“They’re not a little swaggering, they’re swaggering!”

"Director Yuan, since it's too ostentatious, I'll tell them that there aren't that many piers for them to dock, do their work, and let them go back early."

"They managed to save two of them even when there was a major danger. They have indeed made a huge contribution. Isn't it just advertising? Let them do it."

Huang Yuanchang asked with a smile: "Really let them swagger through the market?"

Director Yuan said without hesitation: "They own half of our shares, and they hired us. They are trading in other people's markets. Why not let them go? As for which dock to berth, I will arrange it."

Is this right? Although the Changhang Bureau is in Hanwu, it is two different things from Hanwu.

Huang Yuanchang couldn't help but ask: "Bureau Yuan, which pier do you plan to let the fleet dock?"

Bureau Yuan smiled and said: "Don't they want to see the Yellow Crane Tower and the Yangtze River Bridge? Let them dock at the Yellow Crane Tower Pier!"

"Bureau Yuan, if you arrange this, the comrades will be very happy and excited if they know about it!"

"Not only do we need to arrange dock berths for the triumphant fleet, but we also need to arrange food and accommodation for the entire battalion of officers and soldiers. I was too busy some time ago, and I never bothered to go to Jingzhou to express my condolences. When the large force arrives in Hanwu, we will arrange for all the comrades to arrive. Changhang Hotel, hold a celebration banquet, and I and the heads of the Port Supervision Bureau, Waterway Bureau, Changhang Public Security Bureau, and Communications Bureau will attend."

"Thank you Yuan Bureau..."

"There's nothing to be thankful for. There are so many officers and soldiers of our long-range aviation system in the camp. We should go and toast our comrades."

The achievements achieved by the Linghai Reserve Battalion are also the achievements of the long-range voyage system!

Director Yuan was happy from the bottom of his heart. After thinking about it, he smiled and asked, "Xiao Huang, who came up with the idea of ​​making rescue project materials?"

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

"Local transportation systems are just like transportation systems. I didn't expect that our transportation system would have such enthusiastic and responsible senior comrades."

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

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

Huang Yuanchang briefly introduced the relationship between Lao Ge and Sister Wei, especially the relationship with Xianyu, Xiaoyu and others. He lit a cigarette and added: "I didn't know it at first, but later I learned that it played a huge role in this rescue." The Linghai Road and Bridge Company was established by Comrade Ge Weidong who raised funds from various sources when he was the director of transportation. Hao Qiusheng, the general manager of the Road and Bridge Company, was a cadre he trained, and the cadres and employees of the Road and Bridge Company are also his old subordinates."

Director Yuan was very surprised and said in a deep voice: "So not only his whole family is here!"

"Yes, the Luqiao Company he founded and the old subordinates of the Luqiao Company are also here."

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

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

"Bureau Yuan, I'm reviewing it. The main reason is that I have been too busy during this period and have not been able to take care of it."

"We can't blame you completely. In fact, these situations are all reported by the Port Supervision Bureau, Waterway Bureau and Changhang Public Security Bureau. It can be said that we are obsessed with the authorities."

Director Yuan smiled and continued: "It's not too late to react now. I will ask the office to contact the China Communications News and notify the Yangtze River Shipping News."

…

As night falls, the safety zone built by the Linghai Reserve Camp is crowded with people and brightly lit.

We will be breaking up in a few days, and tonight we will not only have an extra meal, but also have a party.

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

"Search and rescue company, come on, come on, come on! Let's ask you to patter, splash, sweep, and sweep. Come on, come on!"

"Search and rescue team, come one!"

"Come on, search and rescue company!"

"I asked you to sing but you didn't sing. You were so coquettish and unseemly..."

The brats from the 2nd Battalion were in high spirits, singing and shouting at the top of their lungs.

Ma Jintao, the company commander of the water search and rescue company, was having a meeting on the pontoon, 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 bunch of new recruits compete in singing? He immediately stood up and shouted: "The east wind blows and the war drums beat! If you want to sing, who is afraid of whom?"

"Okay, croak croak croak!"

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

"What's the difference between us soldiers? Just because we all wear simple military uniforms. What's the difference between us soldiers? Since we left our hometown, it's hard to see our parents! To say it's different is actually true. They are all the same, they are all in their youthful years, and they are all hot-blooded men..."

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

After singing the "Search and Rescue on the Water" song, there was another burst of warm applause.

A platoon leader from the 2nd Battalion of the 132th Regiment turned to the health room, pointed at the laughing Liang Xiaojun and Han Xiangmeng and shouted: "Doctor Liang, don't be discouraged, Dr. Han, don't be discouraged. What you play with the song is for spirit, and what you play with is friendship." Don’t worry about winning or losing, bringing out feelings is the first priority!”

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

"We can't sing as well as you. We only have a few people in the clinic. You new recruits are bullying people!" Han Xiangmeng got up and pointed at them and cursed with a smile.

"Dr. Han, you can sing solo!"

"Comrades, would you like to invite Dr. Han to perform a female solo?"

"want!"

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

…

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

But I didn’t participate in the singing tonight not because I don’t like the excitement, but because I have to be prepared to withdraw and prepare for the possibility of another flood.

Even though I have been visiting Jingzhou for so many days and rescued so many dangerous situations, I am still like a "firefighter", always exhausted. I only know how to organize forces to follow the guide to rescue, but I don't know the specific situation on both sides of the Jingjiang River. Sometimes I can't even figure out the north, south, east, and west.

The table worker who knows the situation best here is here. Han Yu will naturally not miss this opportunity. As soon as he finishes dinner, he will ask the table worker to give a good talk to the cadres above the team leader.

As a senior expert of the Linghai Reserve Battalion, Xi Gong could not just enjoy the treatment of an expert but not do anything. Not only did he agree, but he also said it very seriously.

"The Yangtze River is thousands of miles long, but the danger lies in the Jingjiang River. This is the consensus formed in the Yangtze River flood control over the years. But why is the Jingjiang River dangerous, and where is the danger?"

The waiter put down the chalk and pointed to the water area map just drawn on the blackboard: "First of all, let's start with the geographical location of Jingjiang River. The Jingjiang River section starts from Zhicheng and goes down to Chenglingji, which is about 347 kilometers long, among which the lotus root is the most important. Chikou is the boundary and is divided into upper Jingjiang River and lower Jingjiang River.

The terrain on both sides of the Jingjiang River is higher in the south and lower in the north. Due to years of flood diversion and sedimentation, the terrain on the south bank is several meters higher than that on the north bank. Most of the area on the north bank was historically an impact plain with intersecting river networks and numerous lakes formed after the disintegration of Yunmengze. The terrain is low-lying, and the flood level in flood season is much higher than the ground inside the embankment.

Once it breaches, the vast Jianghan Plain in northern Jingzhou will be flooded, and even directly threaten Hanwu. In order to resist the raging floods, since 345 AD, after more than 1,600 years of continuous construction by successive dynasties, the 182-kilometer-long Jingjiang Embankment was built from Zaolingang in Jingzhou to the south of Jianli City, the most dangerous place on the north bank.

The Jingjiang Levee has built an important flood control safety 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. The safety of 11 million acres of cultivated land, more than 10 million people's lives and property, and economic and social development in parts of the plain lake area and the Jiangbei area of ​​Hanwu City! "

I had always thought that water conservancy construction at the national, provincial and municipal levels was a bit unfair. The embankment in Jiangbei was better built, while the embankment standard in Anggong was far inferior to that in Jiangbei. It turns out that the Jingjiang embankment in Jiangbei was so important.

Everyone reacted and took notes with pens.

"Secondly, the flood discharge capacity of the Jingjiang River is limited. The current Jingjiang levee can only control floods that occur once in ten years, and even if the Jingjiang flood diversion project is activated, it will only have flood control capabilities that occur once in twenty years."

The bench worker took a deep breath and pointed to the blackboard again: "The maximum safe flood discharge volume in the Jingjiang River section. This flood discharge volume includes the flood discharge volume after the four diversions in Jingnan, which is about 60,000 cubic meters per second. According to historical flood surveys for more than 860 years , the peak flow rate in Changyi upstream was greater than 80,000 cubic meters, which occurred 8 times per second.

Among them, flows greater than 90,000 cubic meters per second occurred five times, especially the two major floods in 1860 and 1870, with peak flow rates as high as 100,000 cubic meters per second and 105,000 cubic meters per second respectively. In 1870, the floods in the upper reaches of the Yangtze River also met the floods in the Qingjiang River, causing the peak flow rate in Zhicheng to be as high as 110,000 cubic meters per second. This shows how big the gap between the huge flood volume in the upper reaches and the safe flood discharge volume of the Jingjiang River is. "

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

"This is a very good question. This is what I will talk about next about the complex relationship between rivers and lakes in the Jingjiang River section."

Xi Gong pointed to the water area map on the blackboard and said solemnly: "The water from the upper reaches flows out of the Three Gorges through Changyi and Zhicheng, and then enters the Jingjiang River section with flat terrain, gentle river bed slope, and curved river channel. There is a confluence of Juzhang River on the north bank. The entrance and exit are located about 20 kilometers upstream of the Sarawak Hydrological Station.

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

There are Songzikou, Taipingkou, Ouchikou and Tiaoxiankou on the south bank. Among them, the Tiaoxiankou was controlled by a gate built in 1959. In fact, only three of them are naturally diverted.

The upstream water flows into Dongting Lake through these four outlets and merges with the water from the Xiang, Zi, Yuan, Li rivers and other small and medium-sized rivers around the lake area. After being regulated and stored by Dongting Lake, it is then merged 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 levee. "

"But on the other hand, the large amount of sediment carried by the floods that flowed 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 been reduced by more than 10 billion cubic meters in the past 100 years. At the same time, the four flood channels The amount of water flowing into the lake from the four branches of the Jingjiang River is also decreasing year by year, and Dongting Lake's ability to regulate and store floods from the Jingjiang River is weakening year by year."

"Especially when floods from small and medium-sized rivers around the Dongting Lake area encounter floods from the Jingjiang River, congestion will occur at the Chenglingji outlet and the water level will rise. The floods from the Jingjiang River will be pushed up and down, causing difficulty in venting, and the Jingjiang embankment will be immersed in the high water for a long time. As the water level increases, the danger will increase sharply. Therefore, the relationship between rivers and lakes has a very significant impact on Jingjiang flood control..."

How can we prevent floods and rescue emergencies if we don’t understand the hydrological conditions?

Everyone benefited a lot, and while they were listening intently, Old Han hurriedly opened the door and walked in.

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

Lao Han held up the mobile phone that Lao Ge had been issued in the afternoon and said solemnly: "My colleague from the Hanwu Meteorological Bureau just called me. There is a cumulonimbus rising in the sky near Hanwu Parrot Island, and it is expanding rapidly like popcorn. !”

"Did the two air currents you mentioned meet over Hanwu this afternoon?"

"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 eight o'clock tomorrow morning, and the space observation results will not be received until nine o'clock tomorrow morning."

Aren't your predictions always inaccurate?

Can you keep it up as always?

Han Yu suddenly felt that it was not good for his father-in-law's prediction to be too accurate, so he couldn't help but ask: "Dad, will it rain in Hanwu?"

Old Han took a few deep breaths and said worriedly: "Hanwu is more than two hundred kilometers away from us, and my radar can barely detect it. From the observation results just now, it can be seen that the moist airflow is stirring over Hanwu rapidly. After climbing more than ten kilometers, the huge amount of water vapor will turn into a downpour."

Han Yu asked: "How long will it last?"

"I don't have much data, and I can't say for sure how long it will rain for the time being. But one thing is certain. As the air flow rises, low pressure will form on the ground, attracting more moist air flow to join, and the heavy rain will be heavy. Maybe it will get out of hand!"

"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 difficult to tell tomorrow afternoon."

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

Xi Gong just said that the reason why the water level of Jingjiang River is so high is because it is affected by upper pressure and lower pressure and cannot vent smoothly. If there is a sudden heavy rain in Hanwu, and the rainfall is heavy, it will definitely raise the water level of Jingjiang River!

Although my father-in-law's 771 radar is an old antique, its main function is to detect rain, otherwise it wouldn't be called a rain-detecting 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 everyone and said with a bitter smile: "Everyone, maybe we won't be able to go back for a while."
