Xinhua News Agency reporters Li Bin and Wang Jun
Typhoon Ute brought continuous heavy rainfall to Guangxi. Xiangzhou county suffered a serious flood disaster on August 19, and more than 4000 people were trapped by the flood. The reporter went to investigate and interview, but the local people said that they had encountered a "strange flood", and the reason for this flood was that a hydropower station in the upstream suddenly opened the gate to release water, but did not inform the downstream in advance.
Is this flood disaster "too rainy" or "too late to warn"? Is it a natural disaster or a man-made disaster? The reporter conducted an in-depth investigation on this.
The sudden flood caused serious property losses.
"At about 7: 30 in the morning, I just walked out of the gate and saw a flood coming in the dark, still rolling the waves. At that time, my legs were shaking. I had never seen such a flood in my life. I turned and ran to the second floor, and the flood followed. " Wei Jinping, a villager in Tian Jun Village, Shura Town, said that the scene at that time was still vivid.
Wei Jinping said that when the flood reached its highest point, it was about 80 cm above the ground, but it only took about 20 minutes for the flood to reach this level. There are still traces of flood on the walls of Wei Jinping's house, and three earth-walled houses collapsed in the flood.
"This flood is so strange." This is the common feeling of the affected people. Many villagers find it strange that the previous flood rose slowly and then slowly receded, but this time it suddenly rose and quickly receded.
"19 At about 8 o'clock in the morning, the Shura River suddenly rose and the water level became larger and larger. In less than half an hour, three houses collapsed in the venue. " Liu Yiting, head of Wangxing Special Wild Boar Farm in Shura Town, Xiangzhou County, recalled.
Wangxing Farm is located on the Shura River. At that time, there were 10 unsuspecting employees on the farm, and the situation was critical, but at this time there was nowhere to escape. Everyone quickly ran to the 2.5-meter-high pool next to the pigsty to avoid danger, which they thought was the safest place in the field. The flood is still soaring, and at the most dangerous time, it is still half a meter away from flooding the pool.
According to the report of Xiangzhou county government, the flood disaster caused the county 1 1 township to be affected to varying degrees, 44 natural villages were soaked, the affected population was 4 1 10,000, and 4,000 people were trapped by the flood. Based on the loss of people's property and water conservancy facilities, the direct economic loss caused by the flood is 65.438+33 billion yuan.
The latest warning information shows that the power station opened the floodgate after the flood.
"Normal flood rises slowly, and it is impossible to rise so suddenly. We heard that it was caused by the flood discharge of the upstream power station, and we want a statement. " The villager Qin said angrily.
About 40 kilometers upstream of Shura Town, there is indeed a medium-sized hydropower station named "Xialiujia Shuniu Hydropower Station". According to the data, Xialiujia Hydropower Station is located in Jinxiu Yao Autonomous County, Laibin City, with an installed capacity of 2×9800 kW and a total investment of1.800 million yuan. Construction started in June 2003, and power generation was connected to the grid in February 2006.
The villagers speculated that the flood was caused by the flood discharge of the upstream power station. A short message received by Wei Shengfan, a villager in Tian Jun Village of Shura Town, confirmed everyone's guess. The text message reads: "Xialiujia Reservoir has been opened for flood discharge, with the largest flood discharge, about 2,800 cubic meters per second. For the safety of you and your family, please tell each other to evacuate the lower reaches of the river quickly. Xialiujia Power Plant announced ".
The reporter saw that Wei Shengfan received this short message at 9: 42 on August 19, and it has been two hours since the flood.
The reporter learned that after the flood receded, few villagers received flood discharge messages, and more villagers were still in the dark.
Liu Yiting told reporters that he didn't receive the warning information before the flood.
Because there is no linkage mechanism of hydrological information, the downstream of flood discharge is unaware of it.
"Before the arrival of the flood, our county flood control office did not receive the notice that Xialiu Household Appliances Station opened the floodgates and released water." Qin Guixue, deputy director of Xiangzhou County Water Conservancy Bureau, told reporters that there is no information communication mechanism between Xialiujia Hydropower Station and Xiangzhou County flood control department. When the floodgate is opened, Xiangzhou County Flood Control Office will not notify. "Maybe they told the Jinxiu County Flood Control Office, or directly notified the downstream towns."
Wei, deputy mayor of Shuluo Town, told the reporter that the town government did not receive the notice of opening the floodgates of the upstream power station.
According to Qin Gui's theory, under the influence of Typhoon Ute, Jinxiu County and Xiangzhou County of Laibin City were hit by heavy rain, causing flash floods. As for the impact of Xialiujia Reservoir flood discharge on the state flood, further confirmation is needed. "Unable to determine the cause of the flood. “
At the emergency video conference held by the Water Resources Department of Guangxi Zhuang Autonomous Region on August 19, when reporting the situation of dangerous reservoirs, he said: "The rainfall in Shengtangshan of Jinxiu Yao Autonomous County exceeded 794.8 mm, which caused the water level of Xialiujia Hydropower Station in the county to rise sharply. Due to the insufficient analysis and prediction of the hydropower station before the arrival of heavy rainfall, the water level was not properly lowered in advance. When the flood came, the sluice flow suddenly increased from tens to thousands, flooding Xiangzhou County 19 villages, causing unnecessary losses. "
Chen Zhenhuan, deputy director of Laibin Water Resources Bureau, said that this situation is "similar to what we know, but it needs further confirmation". Chen Zhenhuan told reporters that the rainfall comes once in a hundred years, and according to the previous forecast, the impact time of Typhoon Yute is from August/KOOC-0/4 to August/KOOC-0/7. No one expected that such a big flood would happen later, and heavy rainfall was the main cause of the disaster.
Chen Zhenhuan told reporters that from 4 am to 5 am on August 19, the flood came from the upper reaches of Xialiu Household Appliances Station, and it was about this time that the floodgates were opened for flood discharge. "At that time, the water came too fast and it was early in the morning, and the flood went down the river in an hour. It is estimated that it is too late to enter the village to inform the villagers one by one. "
The reporter contacted a person surnamed Deng at the power station and asked when the power station would issue early warning information. Deng actually said: "He (the villagers) had time when he received that information!" "I have time to receive the message, so when did you ask me to send it?"
What is puzzling is that the reporter has verified the relevant situation many times, but some local cadres have kept their mouths shut. A cadre even said: "If the masses know that it is the upstream flood discharge, I am afraid that the power station will be besieged, and finally the government will have to maintain stability." (End)
