From 304.5 meters to 310 meters, shops are facing the risk of flooding

At the beginning of June this year, this millennium ancient city experienced a "Dragon Boat Festival Water", which was raging. From June 1st to 4th, there was a heavy rainfall process in Hunan Province.

On the 3rd, the water level in the Changtangang Reservoir in the upper reaches of the ancient city of Phoenix has reached 396 meters, and the super flood -limited alert water level is 4 meters, while the height of the reservoir gate is only 398 meters, which means that if the water level of the reservoir rises by 2 meters, the drim dam will occur. The dangerous situation. However, due to the heavy rainfall, the upstream water enabled the reservoir to enter the reservoir flow of 480 cubic meters per second. In order to ensure the safety of the lives and property of the residents of the ancient city of Phoenix, the Changtan Gang Reservoir could only maintain the flood of 50 cubic meters per second.

At that time, the ancient city of Phoenix 10 kilometers downstream of the reservoir was also severely waterlogged in the ancient city of Phoenix. Under the influence of the premature rainfall, the water level passed by the city reached 304.5 meters. This allows the low -lying streets in the ancient city of Phoenix and the river along the river to have 2 meters deep water, which is about the height of the first floor.

From 8:00 to 8:00 on June 1st, a strong precipitation process in Xiangxi has led to the skyrocketing water of the Phoenix Minjiang River. Yang Ji'an

Prior to the arrival of heavy rain, the meteorological department had passed the national emergencies early warning information release platform, 12379 SMS platform, and the "631" forecast warning "responding" mechanism to conduct targeted reminders to the local people and relevant departments. According to the water level and defense standards, The Phoenix County Government has mobilized about 20,000 staff at all levels from the afternoon of June 3 to the evening, organizing all 1,700 residential shops in the ancient city and 604 households along the river to help the masses transfer their commercials as much as possible. Water breaks and power off and unblocked traffic.

Even so, the threat facing the ancient city has not decreased: Will the rain continue? Should the reservoir continue to flood? Will the water level continue to rise?

On the evening of the 3rd, the county party committee secretary Mao Jia and county magistrate Fan Zhongqing led the members of the meteorological department to go deep into the front line of Phoenix Ancient City and Changtangang Reservoir. On -site survey found that the water level of Changtangang Reservoir has reached 396.13 meters and continues to rise. According to the preliminary forecast, from 20:00 on the 3rd to 8:00 on the 3rd, the rainfall in the rainy rain area of ​​the upper reaches of the Changtan Gang Reservoir still reached 50 to 100 mm, and there were still heavy rainstorms with a single point of a single point of the local area. If the forecast precipitation is all reduced in the rainy rain area of ​​the upper reaches of the Changtanang Reservoir, then the Changtanang Reservoir must flood 700 cubic meters per second, which will directly lead to the water level of the ancient city of Phoenix to 310 meters.

What does the water level of the ancient city of Phoenix rising to 310 meters?

""

If the water level rises to 310 meters, then the large water will directly submerge the second floor of the houses on both sides of the ancient city.

"

Wang Liehui, director of the Meteorological Bureau of Fenghuang County, said that in the face of large water, residents on the first floor along the river have experience, but the residents on the second floor are relatively less experience. The area and loss of the entire ancient city will be far greater than that of Phoenix. The floods appeared on July 15, 2014.

At 3 am, make decisive precision forecast

Whether the precipitation will fall in the rainy area upstream of the Changtan Gang Reservoir, which determines the safety of the lives and property of the people of the ancient city. Facing emergency rain and possible danger, the staff of the Fenghuang County Meteorological Bureau tightened the nerves.

The danger is about to calculate the rainfall in the reservoir area together. After learning about rain, water love, and forecast, the Mao family and Fan Zhongqing immediately instructed the meteorological department to encrypt the business forecast and report the forecast situation by hour.

After receiving the instructions, the staff of the county meteorological bureau encrypted the consultation with the state Meteorological Observatory on the one hand, paying close attention to the radar cloud map, and presenting the latest forecast information to the county party committee and county government. At 3 o'clock on June 4, the County Meteorological Bureau was very sure to report to the county party committee, county government leader and county flood prevention headquarters. 20 mm precipitation will not occur to heavy rain. The county party committee and county government immediately decided not to increase the amount of flood discharge, and keep the outlet flow of 350 cubic meters per second. It not only guarantees the orderly decline in the water level of Changtan Gang, but also makes the water level of the Minjiang River in the ancient city of Phoenix no longer rising, effectively reducing the loss of life and property of the people in the ancient city and the lower reaches of the Minjiang River.

Liao Zhijun, deputy director of the County Natural Resources Bureau, said that during the period of strong rainfall, 94 geological disaster reports were issued in the county. According to the meteorological forecast, he did a good job of defense in advance without causing casualties.

Wang Liehui said that making precision forecasting and providing fine services are inseparable from the achievements of meteorological modernization over the years. Today, the forecasting method has predicted the weather through the only numerical forecast mode, and the process of changing the weather process can be viewed by the short -term intensity of the short -term streaming weather through the radar cloud map; The mechanism is transformed for the government and various departments, and the public; through the years of linkage, who has been withdrawn, how to withdraw, and where to withdraw, there are clear water level standards. Random response.
