On the third day of the flood fight, early in the morning in the tower, Li Zhan saw Li Fengxiang, and then knew that the situation was worse. Li Fengxiang is the chief engineer of the meteorological center of the military region, and at the moment when Super Marie ravaged the urban area of Nangang, he transferred to Longcheng, which shows that the flood control situation here is becoming more and more severe.

The control center of the tower has almost become the "air force branch" of the flood control headquarters, and in addition to the control personnel, half of the space is used by meteorological personnel, and the scope of attention covers four provinces and two regions.

In the past ten hours, the weather has been very bad, and he can't see the road clearly when walking, let alone flying, so Li Zhan has rested a lot and slept very well.

Yu Chenglin and Zhang Wei, the two main tower commanders, and the meteorological personnel headed by Li Fengxiang surrounded the battle table and studied the meteorological cloud map in a low voice, analyzing the current water level in the three river basins. In the past 20 hours, Dam 3 has withstood five flood peaks, and the original sixth and seventh flood peaks will arrive between 17 p.m. and 19 p.m., while new peaks are still forming upstream.

There was a landline and a satellite phone on the combat table, which were specially used to communicate with the flood control headquarters, but at this time, it was like a time bomb, and everyone was afraid to touch them or to ring them.

Li Zhan stood silently in the back and listened to their discussion.

Zhang Yuan, who was holding a colored pencil in his hand, propped his hands on the topographic map, drew a circle at a certain location in the upper reaches of the Three Rivers, and said, "This is the location where the flood peak was formed, the altitude of thousands of meters on the Yunnan-Guizhou Plateau, and it suddenly became more than 100 meters here, with a huge drop and a very rich water supply. Immediately after that, Hong Feng ran eastward almost without hindrance. Dam No. 1 and Dam No. 2 are small dams and old dams, and they can play a very limited role. Therefore, Dam No. 3 is an obstacle that mainly bears the impact force of the flood peak. ”

Yu Chenglin said, "Now the water level of the No. 3 dam has been alarmed, far exceeding the design capacity, and two flood outlets have been opened. When the flood peak arrives, it is necessary to open more flood outlets, otherwise Dam No. 3 is in danger of bursting. ”

"Herein lies the problem." Zhang Yuan nodded to Yu Chenglin and said to Li Fengxiang, "Mr. Li, many embankments in the downstream area have reached critical points, and the troops and local people are strengthening and raising both banks. The No. 3 dam was reopened to the floodport, and these temporarily reinforced and raised embankments could not withstand the huge pressure shock. ”

At this time, Li Zhan saw that Chief Engineer Li Fengxiang was not only a meteorologist, but also one of the main figures who was qualified to make suggestions to the flood control headquarters in terms of flood control decision-making.

The combat atmosphere is very strong, and as far as the troops are concerned, fighting floods and rescuing people is a battle.

"Solution, we have to come up with a way." Li Fengxiang said in a deep voice, "In the next 48 hours, there will be no significant slowdown in precipitation, not only to take into account the flood peaks downstream, but also to take into account the water accumulation in various areas, the situation is even more serious than we expected." ”

Everyone looked at each other, at a loss.

As soon as nature is powerful, human beings have to be confused.

"The only way to divert the flood water upstream and stifle the new flood peak is before it reaches the No. 3 dam, and the remaining difficulties must be overcome." Yu Chenglin said in a deep voice.

Li Fengxiang picked up the pen, drew a circle to circle the upstream river basin, and asked, "The specific plan, where to lead from and where to leak, and what will be the impact?" ”

As soon as he saw the provincial capital city in the circle, Yu Chenglin closed his mouth.

The reason why the discussion plan is not free is that there are urban agglomerations centered on provincial capitals and urban agglomerations in the mountains, and there are many important industrial enterprises and technology research and development enterprises in the upper basin. The location of the provincial capital agglomeration is rather awkward - the three rivers divide it in two and pass through it squarely.

In the upstream flood drainage, where to discharge?

Everywhere it went, it would flood the provincial capital, because it was in the valley.

Otherwise, the same method would have been used a long time ago, and the flood control and rescue headquarters would not have waited until now. What's more, the front-line headquarters of flood fighting and rescue are located in the provincial capital, and they know the local situation best.

"The flood control headquarters wants us to provide a plan, which should mean using fighter planes to bomb, right?" Li Zhan couldn't help but say.

Everyone followed the sound and looked at Li Zhan who was standing behind, and Li Fengxiang beckoned Li Zhan to go over.

Li Zhan walked over and said steadily, "I have an immature idea to bomb the location formed by the flood peak. I have conducted aerial reconnaissance there, and I have seen aerial photographs. The location with the largest drop is actually a long and narrow valley, where the three rivers flow, where two mountains block the north and south sides, so that the three rivers can only flow eastward. Blowing up one of the mountains can play a role in diverting traffic at the source. ”

"The idea is bold!"

Li Fengxiang's eyes lit up, and he gave a thumbs up.

"That's right! There is no human population in the primeval forest area, and it is completely possible to let go of the explosion and the diversion, as long as the flood goes to the north and south, the crisis of the downstream will be lifted! Zhang Yuan said excitedly.

Decades ago, the freezing of the Yellow River caused the water level to skyrocket, and in many places the water level was much higher than the buildings, and finally the Air Force sent bombers to bomb the frozen locations that could not be broken by other means, and the crisis was alleviated. It is said that it was the old guy H-6 who carried out the mission back then, but he was still a young man back then.

Yu Chenglin went on and said, "It is unlikely that we will dispatch bombers, and it is best to use precision bombing, so it is necessary to conduct detailed reconnaissance and detection of the terrain in the target area." I'm afraid this can't be done by airplane aerial photography alone. ”

Zhang Wei raised his hand and said, "The army units can be coordinated, and their army aviation can carry scouts to conduct on-the-spot reconnaissance, and if conditions permit, they can even carry out blasting." ”

"I'm afraid it won't work." Zhang Yuan called up the satellite topographic map, flipped it over, and said, "Small-yield explosives have no effect at all, and the use of a large number of explosives for transportation is a problem, and the evacuation of personnel is also a problem." What's more, judging by the current weather, helicopters can't get in at all. ”

Yu Chenglin said, "They can't get in, and our plane can't take off." Time is so tight, it will definitely not work to move through this road by land. ”

Once again, the solution ran into a problem.

Li Fengxiang stared at the satellite cloud map, the atmosphere became very solemn, he raised his head and said to Zhang Yuan, "Is the latest cloud map coming out?" ”

"I'll ask." Zhang Yuan immediately called the National Satellite Meteorological Center, and when he got a reply, he said, "Immediately uploaded." ”

Li Fengxiang immediately came to the computer terminal and sat in front of the display screen, waiting to receive the real-time satellite weather cloud map. The troops have not yet established a real-time sharing platform with the National Satellite Meteorological Center, and communication can only be carried out through the network to transmit documents.

When the latest satellite cloud map arrived, Li Fengxiang carefully looked at it frame by frame, sometimes zooming in to see the subtle places, sometimes zooming out to see the overall situation. Frequently refer to the analysis and forecast reports sent together, supplemented by their own thinking.

Slowly, everyone understood what Chief Engineer Li Fengxiang was doing - he was looking for a time window.
