Siheyuan: I eat melons while doing scientific research

Chapter 1131: A Disaster
All comrades were invited into a large conference room.

The Emergency Management Bureau is a bureau in name, but its rank is the same as that of a ministry. Also here are the director of the Emergency Management Bureau, comrades from other ministries, including comrades from the National Defense Working Committee and the Army.

Looking at this strange and diverse personnel configuration, Gao Zhendong vaguely guessed something.

"Comrades, let me first report a piece of good news to you all! Just a few hours ago, our second satellite, the imaging remote sensing satellite 'Experiment No. 1', was successfully launched at the Northwest Satellite Launch Center! And it successfully transmitted back real-time remote sensing images."

The director of the Emergency Management Bureau first reported the good news, but no one quite understood why the Emergency Management Bureau was the one to report the good news. In any case, the leader of the Defense Work Committee sitting next to him was the more suitable choice.

No matter what, this good news still makes everyone very happy. The first satellite was launched just over a month ago, and the second satellite that can do more work is already launched into space?

Not to mention others, even Gao Zhendong, who was more familiar with "Experiment No. 1", felt a little surprised. It was really fast!
There was a round of applause in the conference room, but everyone stopped soon. It was obvious that inviting everyone to the Emergency Department was probably not just about good news, but also bad news.

Gao Zhendong was almost sure what had happened, because he had an elder in his previous life who was engaged in water conservancy, so he had an impression of this incident.

"However, the first batch of photos taken by this satellite brought us some not-so-good news. Comrades, please take a look."

A monitor displayed a black-and-white photo.

There is a large rain cloud in the sky over several provinces south of the capital, and the amount is very heavy!

This rain cloud covers these provinces tightly!

"Comrades, you have seen that this rain cloud is unusually large and may bring a lot of precipitation. I called you here to discuss with you how to deal with this matter."

The rain hasn't started yet, and it's still unclear whether it will rain or how heavy it will be when it does, so the comrades are still relatively relaxed, especially the young comrades.

But the older comrades frowned.

The rain hasn't fallen yet, but the old sayings "water and fire are merciless" and "don't bully the mountain, don't bully the water" are always valuable.

"This area is too large. It almost covers the entire Daohai River Basin. It's very difficult to deal with."

"If we have to deal with it, the impact on production and life will be too great! The area is too large."

"But if we don't respond, what if a disaster occurs?"

“What if we respond and the disaster is not as serious as expected?”

"It looks like a large area, so the possibility of it becoming a disaster is not small."

"But large patches don't necessarily mean heavy rain. If the thickness is not too large, then it won't be a big problem."

"..."

The comrades talked at once, and no one could agree on an opinion, but everyone had a point.

Gao Zhendong raised his hand and said, "The cloud cover is easy to deal with. We can immediately pull the latest air defense missile radar over and use it to scan and we will know. Or we can use the Be-6 patrol plane from Bluebird City to fly over and scan and we will know. But..."

Radar cloud map is a very common meteorological means in the future. Although air defense missile radar is not specialized in this, it is still helpful for judging rain clouds.

The comrades in the army immediately picked up the phone at the scene and said, "Notify the Be-6 patrol aircraft at the Yuandao base in Qingniao City to set off immediately!"

Other comrades were more interested in Gao Zhendong's "but".

"But what?" The leaders of the Emergency Management Bureau attached great importance to this comrade who had made great efforts in the last rescue operation at such a young age, not to mention that there were people from the Defense Work Committee standing by.

Gao Zhendong continued: "But I suggest that we empty the reservoirs now! All the reservoirs in the basin should be emptied. And we must be prepared for emergency rescue in case of reservoir overflow."

"Empty it? The dry season is coming in two months. Isn't it a bit inappropriate to empty the reservoir now?" A comrade hesitated.

"Yes, there are hundreds of reservoirs in this area, large and small. Are they all drained? If there wasn't such a serious disaster, I'm afraid I would be scolded to death by the people."

"Flooding the dam? It can't be that serious, right?"

Gao Zhendong shook his head: "I stick to my opinion!"

These were serious statements. As one of the highest-level technical consultants at the Emergency Management Bureau, Gao Zhendong's words carried great weight.

The leader of the Emergency Management Bureau looked at Gao Zhendong and said, "Comrade Zhendong, what did you see?"

I didn't see anything, but I remembered something.

Gao Zhendong was very clear about how serious this matter was.

"Look here!" Gao Zhendong pointed to the southwest corner of the photo.

"Here? What is here?" It still looks like a cloud, nothing special.

"Low pressure in the southwest continues to form and is constantly building up in this direction!"

Actually, it is not very obvious from this picture, but Gao Zhendong does not need to explain now. I said I saw it, and that is it. And what he said is a fact that has been happening all the time. If he did not point it out, comrades might not have considered it. Now that he has pointed it out, it is much easier to find the problem with the answer.

Gao Zhendong was well aware that this rainstorm was extremely heavy, and the center of the rainstorm even set the highest record for accumulated rainfall in inland my country for seven consecutive days, reaching more than 7 mm.

How much rainfall is this? Well, in general, in areas with abundant rainfall, it only rains this much in a year.

So Gao Zhendong had to at least try to save as many people as possible.

"It does seem a little interesting. Has the satellite taken any photos in a direction slightly more southwest?" A meteorological expert pushed his glasses.

"Yes. After discovering this problem, the comrades in charge of controlling the satellite took multiple photos of the surrounding area in succession. And if necessary, the satellite will return over the area every two hours and can be called upon to take photos repeatedly." A comrade from the Emergency Management Bureau operated the computer, flipping through the photos one by one.

Huh? Are we so advanced now? We can actually use satellites to repeatedly stare at a certain area?
The meteorological experts stared at the photos for a while, then looked at the data sent by the nearby weather station, and raised their heads: "This comrade is right. This area is now under the control of deep low pressure. Affected by the uplift of the mountains, the cold and warm are intertwined, and the low pressure in the southwest is also constantly superimposed! The possibility of heavy rain is very high!"

Gao Zhendong pointed at the water system map of the Daohai River again: "And judging from the monsoon wind direction, if a rainstorm forms, the rainstorm peak will move from south to north, which will bring a big problem - the rainfall runoff of each tributary, as well as the rainfall itself, will reach the downstream plain at almost the same time!"

The Daohai River flows from south to north, which is exactly the same direction as the movement of Yufeng.

"Hiss~~~~~~" All the comrades present took a deep breath.

"Is it that serious?" The leader of the Emergency Management Bureau was a little bit unbelievable.

The comrades from the hydrology and meteorology departments followed Gao Zhendong's instructions and looked at the water system map of the Daohai River. After estimating for a long time, they looked at the comrades from the Emergency Management Bureau and nodded heavily.

"So it seems that a disaster is almost inevitable?"

"Yes, the probability is very high. And once it becomes a disaster, a reduction in grain production and damage to industry in this area are almost certain to occur." The meteorological and hydrological experts said in a heavy tone.

"So, directly inform the comrades in this area to harvest the crops that can be harvested first! Try to reduce the losses as much as possible."

"Well, at the same time, they need to prepare a disaster prevention plan to minimize the losses as much as possible, at least no one should be hurt."

"The work of emptying the reservoir that Comrade Zhendong just mentioned must be done immediately. If the conditions are too bad, just blow it up!"

Comrades spoke up and offered suggestions.

Gao Zhendong did not fall behind: "I think this time, the main thing is to protect people. Judging from the current conditions, this time the flood is almost in the entire basin and the entire river section. We must try our best to give full play to the functions of water conservancy projects, but we cannot pin all our hopes on water conservancy projects, because this time, I estimate that the flood indicators will exceed the design indicators of quite a few water conservancy projects and cannot be prevented."

"Comrade Zhendong is right. Based on my experience, I estimated that the downstream flood flow this time will not be less than 6 cubic meters per second. It is very serious." Comrades engaged in water conservancy are very experienced. Although there is no observation data yet, he still estimated a number that is roughly the same. The number Gao Zhendong knows is even larger than this number.

"Is there enough time?" This is what the Emergency Management Bureau is most worried about.

"There is definitely not enough time, no matter how much time we have," said a comrade.

“When is this rain likely to fall?”

"It's hard to say right now due to lack of data, but it should be soon."

"Report! The Air Force's Be-6 has sent back the rain cloud data!"

"Quick, quick, let me see..."

After all, the Be-6 is not a professional weather aircraft, and the radar on it is not a weather radar, but it is more or less useful, and the data transmitted back can be summarized in two words.

Thick and large.

If the size of the object had already been confirmed by satellite photos, then the fact that it was thick almost put the final nail in the coffin.

"It will definitely be a disaster! There is a high probability that it will rain around the 1st!" The meteorological expert took the data, compared it with the satellite photos, calculated for a long time, pushed his glasses, and said with absolute certainty.

Gao Zhendong was relieved. He didn't need to find an opportunity to predict the rain time by himself. The expert's prediction was very accurate. If he predicted the rain time by himself, it would be very strange, so he avoided it if he could.

The second shoe finally fell. The comrades no longer thought about anything else. Now they only thought about one thing: how to reduce the losses!

"Notify the railway department..."

"Mobilize flood control materials..."

"Mobilize nearby garrisons..."

"Organize the harvest on the spot..."

"Inspect the hydraulic works and dikes..."

"Industrial factories and mines should make good preparations for disasters..."

Opinions and decisions were put forward and implemented, and plans took shape quickly.
