長江上游幹支流在同日內形成3個編號洪水 三峽大壩撐不住了 加大洩洪

Hello, everyone. Welcome to Vision China. I'm Xiaokun. Due to the impact of the Yangtze River fish, the surface of the Yangtze River, the Jialing River, and the water supply between the mountains and the gorge have increased significantly. The water flow into the gorge has increased rapidly. On July 11, local time, the water level rose to 50,000 cubic meters per second, which reached the standard level of flood. Minister of Water Resources Jiang Shui-li officially announced that flood No. 2 in 2024 will form upstream in the Yangtze River To welcome the flood, the Three Gorges Dam began to reduce water level from July 9. According to the water level of the Yangtze River water network, on July 12, the water flow into the Three Gorges Dam reached 540,000 cubic meters per second, and the water flow out of the gorge reached 330,000 cubic meters per second. The Three Gorges Dam reduced water level by four holes. After that, the Three Gorges Dam continued to increase the reduction of water level. On July 13, the Three Gorges Dam increased to six more holes. On the 18th, the water level of the Three Gorges Dam reached 166.4 meters, which exceeded the flood level of 21.4 meters. The water flow into the gorge reached 420,000 cubic meters per second, and the water flow out of the gorge reached 370,000 cubic meters per second. According to the media, the flood No. 2 in the Yangtze River will reach the Three Gorges Dam on July 16. At that time, the pressure of the Three Gorges Dam increased, and the reduction of water level will continue to increase. On the morning of No. 11, the flood No. 1 in the Jialing River in 2024 formed in its stream Qujiang. Jialing River is one of the main streams upstream of the Yangtze River. Liujin, Shaanxi Province, Gansu Province, Sichuan Province, Chongqing City will enter the Yangtze River in Chongqing City Chaotianmen. On July 11 and 12, the Yangtze River upstream stream is also the largest stream in the Three Gorges Dam, forming the flood No. 1 in the Daming River in 2024. This river originates from Shaanxi, and flows southward through Wuxi County, Chongqing, and enters the Yangtze River in Wujiang County. In other words, the upstream stream of the Yangtze River will form three floods on the same day, and they will all pass through Chongqing, which increases the flood prevention pressure in Chongqing. According to the Chongqing City flood monitoring data, from No. 10.80 to No. 12.80, there were 12 areas in Chongqing that were hit by heavy rain. This also caused the flood level to rise in several reservoirs upstream, and was affected by heavy rain and upstream water. The flood level rose, and 29 rivers in the city were flooded with water. Chongqing was flooded with flood water, and the water pipes formed city prisons, and the roads were also damaged. On July 11, the Yangtze River upstream stream quickly rose in Chongqing, causing a bridge on the upstream stream to collapse, and it was submerged in the water. The scene was very scary. On July 11, the water power station on the Puzi River in Pengshui County, Chongqing was flooded with flood water. As you can see in the video, the flood water flowed down and washed down a lot of rocks. From July 9 to July 12, the Yangtze River upstream stream and the Jialing River Basin were the largest floods since the flood. On the morning of the 10th, the first wave of flooding had arrived in the center of Chongqing. Mr. Fang in Chongqing witnessed the scene of the flood in his hometown. To this day, there is still a record. Oh my god, the streets are flooded. It's so scary. The streets have been flooded to 3 meters deep. I pulled down the curtain door of my store, but I didn't expect the water to be too big and took my curtain door away. On July 12, the flood entered Chongqing and flooded the Sanhui District of Chongqing. A person trapped at home took a video and said the flood was too big. The store below was flooded. Now the water level has almost reached the second floor. It's almost two meters high. You see, I've never seen such a big flood. You see, the water can lift the car up. The water level is still rising. The water is rising too fast. It can rise to this height in a minute. This is the scene of the flood in the main city of Chongqing on July 12. In the video, you can see the flurry of floods passing through the dam and entering the city. The rainbow road, which was just repaired this year, was also flooded. The trees have grown into the river. A factory in Chongqing was flooded. The boss suffered heavy losses. He was so emotional that he said, it's all over. The raw materials and packaging equipment were all flooded by the flood. The Wuxi County of Daning River is also severely affected. I am now in the ancient city of Daning At present, the river has spread to the road surface. The water level has reached 209 meters. The shops on the street are urgently evacuating. The rainstorm is still going on. This is the picture after the flood. You can see a lot of cars being washed away by the flood on the street. The road was also washed away. The shops on the street suffered even more losses. A restaurant owner said he had nothing except for the rent and loan. On July 11, there was a flood in Changshou, Chongqing. Part of the road was cut off by three meters deep. Some streets and low-rise housing were flooded. Houses on both sides of Yuntai Town and farmland were flooded. A large number of farmers were trapped. According to media reports, Chongqing was flooded in many places, including Changshou, Zhongxian, Fengdu, Dianjiang, Wuxi and other places. According to the authorities, the heavy rain caused 14 counties and 6,985 people to suffer. Dianjiang County suffered the most. From July 10 to July 11, there was a heavy rain in Dianjiang County, Chongqing. Part of the road was cut off by two meters deep. Local people said the rain was so heavy last night that it became like this overnight. I haven't seen it for decades. Many villagers were trapped by the fast-growing flood. Some villagers who couldn't escape died in the flood. At least six people have died. According to the video, a car parked in a residential area was almost drowned. I can't get out. I can't get out at all. Who will save me? According to media reports, there was a landslide in Longquan Village, Gangjia Town. A house was washed away by the flood. The three grandchildren in the house were unfortunately killed. A villager surnamed Hu in Longquan Village said that at 6 a.m. on the 11th, when he was investigating the disaster, he found a three-story house Because of the landslide, Wang Mou and his mother and son were trapped in the collapsed house and unfortunately died. The family of the deceased was an 80-year-old grandmother, a 50-year-old son, and a 20-year-old grandson. The grandson was a college student and came back during the summer vacation. The grandson's mother was not at home. According to local villagers, the back of the house is a loose land. The house collapsed after the rain. According to him, there are more old houses and micro houses in the area, and the most severe disaster is the place below the line. The villagers said that the local rainwater is like pouring it down with a basin. The flood in Chenxi Town is 2-3 meters deep, and the car can't see the top. According to Lu Mei, the goods and goods of a 2,000-square-meter supermarket in Wudong Town, Chongqing were washed away. One of the supermarket partners, Mr. He, said that it suddenly rained heavily at night and when the flood came, the water level in the city was more than 1.5 meters. The goods and goods of the supermarket were washed away, and 90% of the goods were damaged. It is expected to lose 1-2 million yuan. Mr. He said that there was only a small river ditch nearby, and he didn't know why the water was so big. It had never been flooded before. In addition, Sichuan Province, which is also located upstream of the Yangtze River, is also severely affected. This is Dazhou City, Sichuan Province. As you can see in the video, the local area has become a mess. The photographer said that now it has been flooded to the second floor. Many cars parked on the street have been submerged. The upstream water in the Yangtze River has increased, and the Three Gorges Dam continues to flood, causing concern among the people downstream. After the ditch was blocked on July 5 at the first line of Dongting Lake in Hunan, which is downstream of the Yangtze River, the ditch was blocked until the evening of August 8. But after the ditch was blocked, Hunan, Yueyang, Huarong County, and Tanzhou County, which were submerged by the flood, were still in the water. There is still 2.1 billion cubic meters of water in the dam, and the second line of the dam continues to flood. The landslide in Dongting Lake caused heavy losses to tens of thousands of people, and the authorities are even more absurd and incompetent in dealing with the disaster. From the beginning, the roadside collapsed on the roadside of the dam, and then after the sudden dam, it failed to block the gap with sand, and then the water level outside Dongting Lake was not leveled, and a large amount of manpower was used to block the gap, and then the local officials arranged a large number of people to dance and celebrate on the scene of the flood. The late disaster was regarded as a show of officials, without revealing the low level of officials' governance and decision-making ability. More absurdly, the official blocked the gap when the water level outside the lake was leveled, which was useless. The political significance is greater than the technical significance. After that, the water level of Dongting Lake was removed, and the water in the yard was flooded, but it could not be returned. Officials naturally did not want to reopen the gap and let the water flow out. This is too embarrassing. They can only spend a lot of money and choose to draw water by hand. The authorities also mobilized dozens of firetrucks to draw water on the lake floor. The scene was spectacular, but the cost was also considerable, so a lot of disaster relief funds were wasted. And for the victims who lost their homes, the authorities were not willing to have any compensation If the Three Gorges Dam continues to be flooded, the water level of Dongting Lake will surely rise again. The dam that just blocked the gap will probably be flushed again, so that the people who were originally affected will be flooded again. If it is not flooded, there will be a larger area in Chongqing that will be engulfed by flood water. According to the weather forecast, in the next 10 days, the Yangtze River will continue to flow, and I don't know how many people will suffer from the flood. The flood in Chongqing has caused many people's homes to be destroyed, and tens of thousands of people have lost a lot of property. While sympathizing with them, many people are also thinking why Chongqing is flooded again, why Chongqing and Wuhan have to be flooded every year for many years? To sum up the analysis of the experts, the Three Gorges Project has a major responsibility It plays at least two roles. First, it has increased the rainfall in the surrounding areas of Chongqing. Second, Chongqing is located at the mouth of the Shanxia reservoir, and the water level in the Yangtze River is high. Scholars such as Jin Zhongwu and Guo Yihao studied the corresponding relationship between the water level change and the flow of the Yangtze River in the Chuntan Yangtze River flood station in Jiangbei District, Chongqing from July 1981 to August 2020. The results show that before the flood in the Shanxia dam, the Chuntan water level in Chongqing was almost completely determined by the flow of the Yangtze River. After the flood in the Shanxia dam, the water level in the Shanxia dam was still on the same line at 145 meters and 155 meters. At this time, the water level in the Chuntan dam had nothing to do with the water level in the Shanxia dam. When the water level in the Shanxia dam rose to 156 meters, the water level reached the Chuntan dam, and the water level in the Shanxia dam added to the flood in Chongqing. For example, at 10 a.m. on August 20, 2020, the flow of the Chuntan dam was 74,500 cubic meters per second. If the Shanxia dam had no water, the Chuntan water level corresponded to 188.3 meters At this time, the Chuntan dam's actual water level was 191.55 meters, which was 3.25 meters higher The 3.25 meters high is the additional flood level brought by the water level in the Shanxia dam. In other words, at 10 a.m. on August 20, 2020, when Chongqing Chuntan was close to the highest flood level, the water level of about 3.3 meters was contributed by the water level in the Shanxia dam. This also explains why the flood flow in Chongqing Chuntan was much smaller than in 1981, but the water level broke the record. Of course, the flood level of the Chuntan and Changjiang Chongqing urban areas in the Shanxia dam is related to the flood level in Chongqing Chuntan, as well as the flood level in the dam. As of the publication of the article, the water level in the Shanxia dam was 166.4 meters, and the Chuntan water level was 176.8 meters. The Chuntan water level was 29,700 cubic meters per second. According to historical observation data, if there was no Shanxia project, the Chuntan water level should be about 173.7 meters, and the water level should be about 3.2 meters higher. 3.2 meters doesn't seem to be a big number, but according to China's housing design regulations, the housing height is 2.8 meters. This 3.2 meters of water is enough to completely flood a building. Former Politburo Standing Committee Deputy Prime Minister of the State Council Wang Yang served as the Director of the General Reception Committee of the Shanxia Project. He served as the Secretary of the Chongqing Municipal Party Committee from 2005 to 2007. During this period, he was in charge of the overall planning of the Chongqing city. The plan stipulates that the main public buildings in Chongqing must be built in areas with an altitude of more than 220 meters. In other words, which is less than 220 meters above sea level, will become a desert area with a 100-year flood, and will become a restricted development area or an abandoned area in the city plan. Later, Chongqing gave up the landmark buildings Ciquikou and other places. Chongqing has a large number of roads, shops, residential buildings, Ciquikou, Chaotianmen, Nanbin Road, and other landmark areas, with relatively low altitudes. Among them, the top of the Chaotianmen Pier is only about 160 meters above sea level. Since 2008, the Sanxia project began to flood the city. Since 2008, the Sanxia project began to flood the city. It has happened four times. On average, it happens once every three years. Among them, the flood in August 2020 is the most dangerous. According to professionals' calculations, if for some reason, such as a super flood in Chongqing to the Sanxia dam, or if the dam is accidentally flooded, the water level in front of the Sanxia dam reaches 175 meters, the water level in front of the Sanxia dam is about 10 to 16.5 meters. If the current traffic calculation shows that the water level in front of the dam reaches 175 meters, the water level in front of the Sanxia dam is at least 187 meters. When the Sanxia project was designed and built, the CCP claimed that it had functions such as anti-flooding, power generation, and navigation. But if it really let the Sanxia dam play the anti-flooding function, what would happen? A week ago, a flood occurred in the Dongting Lake area downstream of Sanxia, which caused a landslide and caused a landslide on July 5. The authorities said that the Sanxia dam reduced the amount of floodwater downstream and helped the Dongting Lake to reduce the flood. The result of the blue and red is that Chongqing was flooded. On July 10, the Sanxia dam opened a flood hole and increased the amount of water, from 27,000 cubic meters per second to 31,000 cubic meters per second. As of the draft, the amount of water was 37,300 cubic meters per second. At the same time, the No. 1 flood downstream of the Yangtze River had not yet entered the sea. The role of the Sanxia Dam in this process is that 1. When the Dongting Lake was flooded, it was still red, which exacerbated the downstream Dongting Lake flood. 2. The blue and red flooded Chongqing. 3. After flooding Chongqing, it flooded the downstream Dongting Lake and Wuhan. Poor Dongting Lake, the dam has just been blocked. I'm afraid it might be washed away again. Poor people affected by the flood in Dongting Lake. They may have just returned home, and their house is still in a mess. They may be flooded again. As for why every flood season, the Sanxia Dam only starts to flood, the effect is always to flood not only the upstream Chongqing, but also the downstream Wuhan. A well-known water engineering expert, Wang Weiluo pointed out that the flood-resistant reservoir in the Sanxia Dam is not as big as the authorities said. According to the data released by the CCP, the total reservoir in the Sanxia Dam is 39.3 billion cubic meters, and the flood-resistant reservoir is 221.5 billion cubic meters. This accounts for 8% and 5% Therefore, from a technical point of view, the flood-resistant effect of the Sanxia Dam is very limited. Is this so-called flood-resistant reservoir still a wrong data? The reason for the error is that in the design of the Sanxia Dam, there is a major error in the water slope calculation. In the design of the Sanxia Dam, the water slope is only considered according to 1 to 2 meters, that is to say, in the Sanxia Dam full reservoir, upstream and downstream, the flood-resistant water level of the Sanxia Dam and the reservoir water level may appear 1 to 2 meters of water difference. In fact, the water slope of the Sanxia Dam is variable, and the variability may be large. Even in October 2010, the actual water slope of the Sanxia Dam was less than 1 meter, but it cannot be deduced that the actual water slope of the Sanxia Dam was less than 1 meter in the flood season. In fact, the flood season flow is very large, and the water slope must be many times larger. For example, on August 6, 2009, the water level of the Sanxia Dam was 145 meters, and the water level of Chongqing Chaotianmen was 183 meters. Chongqing's main urban area was flooded, and the water level difference was up to 35 meters. Of course, there are other factors such as upstream flood, but it is obvious that the water slope of the Sanxia Dam is a major reason. If there is no Sanxia Dam, the flood process may flood Wuhan once. If the Sanxia Dam is activated to prevent flooding, Wuhan will be flooded at least twice, and Chongqing will be flooded once. The Sanxia reservoir also causes a significant increase in rainfall Nanjing Information Engineering University Zao Zihao and others studied the data of 10 weather stations in the Sanxia Reservoir in 2022, analyzed the characteristics of climate change in the Sanxia Reservoir in the past 66 years, and the impact of the Sanxia Reservoir on local climate change. The results show that the Sanxia Reservoir reservoir causes an increase in local precipitation and affects the area of 2915 square kilometers near the dam, the largest impact distance is 109 kilometers near the dam, and the Sanxia Reservoir is exactly 109 kilometers away from Dazhou. A study report by NASA in 2006 used satellite data and high-precision digital simulation technology to analyze the impact of the Sanxia Reservoir on local precipitation and surface temperature. The basic conclusion is that the Sanxia Reservoir project has a significant increase between the Great Barrier Reef to the Qingling River. Sanxia Reservoir has changed significantly in terms of temperature, humidity, precipitation, etc. such as Fan Xiao and other experts. It is more striking that the Sanxia Reservoir is located in the northeast of Sichuan Province, mainly including Sichuan, Dazhou, Bajiong, Guang'an, Nanchong, Chongqing, Kaixian and other places, where there are rare cases of continuous rainstorms, which is the most serious in Dazhou. Experts such as Fan Xiao found that the Sanxia Reservoir was flooded for the second time in September 2004. Dazhou, which has been drought-stricken for 10 years in history, has suffered hundreds of years of heavy rainstorms. According to many towns along the river, the water level can reach up to 20-30 meters. Experts calculated the rainstorms in the northeast from 2004 to 2014 97% of them were heavy rainstorms with a rainfall rate of 100-250 mm in 24 hours or heavy rainstorms with a rainfall rate of more than 250 mm in 24 hours. According to the data collected in the 32 rainstorms, the direct economic loss was as high as 297.1 billion yuan. In addition, in the 12 rainstorms in Dazhou, a total of 198 people died and 106 people disappeared. The data show that the impact of the Sanxia project on the climate has been studied and predicted The impact of the flood is described as the increased water volume of the Sanxia Reservoir However, due to the impact of the low-temperature effect warm and wet airflow will push the rain to the farther terrain in different seasons. The rainfall in these areas will increase. These areas, such as Dazhou, Bazhong, Guang'an, Nanchong, Chongqing, Kaixian, and so on, are located on the south slope of Mount Daba. The terrain is also called the Yangtze River and the middle of the Sichuan basin. The water in these areas mostly flows into the Jialing River Finally, it enters the Yangtze River through the Chaotianmen in Chongqing. From the above analysis, the flood in Chongqing and the Sanxia dam are hard to escape. However, the Chinese Communist Party has repeatedly claimed that this is due to the extreme weather around the Sanxia Reservoir and has nothing to do with the Sanxia project.
