The No. 2 flood of 2020 on the Yangtze River was formed upstream, what is the impact on the Yangtze

Flood No. 2 greatly reduced the safety of the entire Yangtze River and posed a great threat to the people and regions in the Yangtze River basin.

The arrival of the No. 2 flood has made the inflow of the Three Gorges Reservoir reach 50,000 cubic meters per second, and this figure is expected to reach 55,000 cubic meters per second. In this case, in the case of heavy rainfall in the upstream, the flood storage of the Three Gorges Reservoir will inevitably have a certain impact on the upstream, and the continuous rise of the water level will make the upstream areas face certain pressure, but will not cause the upstream areas to suffer due to poor flood discharge, but need to share some flood risks. <>

The huge flow of the No. 2 flood also makes the Three Gorges Reservoir itself have certain hidden dangers, which are inevitable, and the dam body of the Three Gorges Dam will also face more or less tests in the case of impounding high water levels, but in essence, the dam will not appear in any danger, and once the guaranteed water level is exceeded, the flood discharge will be opened. As a result, the formation of Flood No. 2 made the Three Gorges Dam, the lifeblood of the Yangtze River, take risks and tests

The most critical is to pose a considerable threat to the middle and lower reaches. In Hubei, Anhui, Jiangxi and other provinces are generally affected by the situation, the reservoirs have exceeded the warning water level or even the guaranteed water level, all tributaries, reservoir lakes have been full capacity, Anhui and other places have started the plan to break the polder flood discharge, in this situation, the formation of the No. 2 flood is undoubtedly a great challenge. This has greatly reduced the safety of the Yangtze River, and the residents and production areas in the Yangtze River basin will be put to great test

The occurrence of major floods will also cause certain changes in the direction of the main stream and tributaries of the Yangtze River, and partially affect the surrounding ecology, and the severe situation caused by the No. 2 flood will make great changes in the flood control, flood storage and flood discharge measures of the reservoirs, and this human intervention will also have a certain impact on the ecological environment of the Yangtze River species.

All in all, the No. 2 flood of 2020 will make the entire Yangtze River basin extremely dangerous, and it will also be a huge test for the party and the people. <>

There will definitely be an impact, as long as there will be no more heavy rainfall in the future, the impact on the Yangtze River will not have a great impact, and it is still under control.

The No. 2 flood formed in the upper reaches, the capacity of the Three Gorges Reservoir increased sharply, the water level of the Yangtze River was greatly improved, and natural disasters such as floods and mudslides may occur in local areas.

It will make the Yangtze River very dangerous, and it will greatly threaten the living and breeding of local people.

As a result, the flow of the Three Gorges Reservoir is rapid**. This has led to landslides, landslides and other geological disasters. Jiangxi and other places have invested 10,000 rescue manpower. That's a lot of data.

The formation of Flood No. 2 upstream is likely to lead to the water level of the Yangtze River**, which will cause natural disasters such as floods and mudslides in local areas, which will cause a large number of economic impacts.

Hello. According to **, the precipitation in the flood season (May-October) in the Yangtze River basin in 2022 is normally less, of which the upper reaches of the Yangtze River are more normal and the middle and lower reaches are normal; During the main flood season (June to August), the precipitation is normally low, with more precipitation in the upper reaches of the Yangtze River and less in the middle and lower reaches of the Yangtze River. According to the comprehensive spine guess or joint research, the risk of regional floods in the upper reaches of the Yangtze River during the flood season this year is high, and the probability of drought and water shortage in the middle and lower reaches is high.

Summary. Hello, there will be big floods in the middle and lower reaches of the Yangtze River in 2023. According to the research and judgment of the meeting, during the flood season (April to October) this year, the climate of the Yangtze River basin is generally deviated, and the drought is heavier than the flood; During the main flood season (June to August), the precipitation in the Yangtze River basin is relatively low, among which the upper reaches of the Yangtze River are basically normal, the middle and lower reaches are less, and the rainy areas are mainly located in the southwest of the upper reaches of the Yangtze River and the south of the two lakes system, and the precipitation near the main stream of the middle reaches of the Yangtze River is obviously less.

It is necessary to be vigilant against local heavy rain and floods that may occur in the upper reaches of the Yangtze River and the two lakes, and drought disasters may occur in the main stream and north of the middle and lower reaches. It is expected that there will be two precipitation processes in the Yangtze River basin in the coming week, and the rainfall will be concentrated in the two lakes and the main stream of the lower reaches of the Yangtze River, and the water level of the main control stations in the middle and lower reaches will fluctuate**.

There is a person who supports and rushes at you, that is your fate of Ming and Annihilation; Having someone help you is a merit of your own past life. Thank you for your inquiry, and answer your questions immediately.

I think the first thing to do is to arrange for the people next to you to evacuate, because the flood usually affects the houses that go to the river first, and the people who live in the houses may be affected, so they should evacuate at this time. In addition, it is necessary to carry out a series of anti-flood actions such as reinforcing the adjacent embankments, which can collapse if they are not strong, which can be very dangerous. Flood is a very terrible natural disaster for our ordinary people, because once the flood is formed, it will cause a lot of loss of life and property, at least people's homes will be destroyed by the flood, so we must do a lot of prevention and control measures for the formation of floods, and now I will talk about my personal views on prevention and control measures.

First, first of all, it is necessary to arrange for the evacuation of the people along the Yangtze River.

If there is a flood, the first person to be affected is the people next to the Yangtze River, because he and the Meng people live next to the Yangtze River, and soon the Chanjin Bridge will be invaded by floods. Therefore, we must arrange for them to evacuate in time, regardless of whether there is a flood on the shore or not, and if there is such a situation, we must evacuate in time, so as to ensure the safety of their lives and property. It is also necessary to make a decision on whether to evacuate people from afar, depending on the flood situation.

Second, the government should organize personnel to carry out an investigation of the river embankment.

In addition, ** and some official organizations should promptly check whether there is a risk of collapse of the river embankment next to it. In most cases, these embankments are very strong and have been reinforced for years or even decades, but there are still some hidden conditions that must be investigated in time to avoid the disasters caused by floods.

3. When there is a flood, there should be no boats on the river.

Although the Yangtze River is a river, there are many ships transporting on the river, because the Yangtze River has very good transportation conditions. Of course, there is nothing wrong with it in normal times, but it is very dangerous for these ships when there is a flood, so it is important to tow these sailing ships to the shore in time to avoid danger.

In addition, there are many flood prevention measures to be taken, which depends on the local situation.

1. River remediation, embankment and other engineering means to expand the river discharge and impound the flood to reduce flood disasters; 2. Strengthen flood forecasting, floodplain management and other means to avoid lifting and prevent flood invasion.

The following three aspects of flood control work should be done, the first is to inspect the embankment sail with the forest dam and the river in advance to ensure that the fortifications are perfect, and for damaged and weak places, they should be reinforced in a timely manner; The second is to make rational use of dams and reservoirs in various places to store and divert floodwaters; The third is to do a good job in prevention and publicity, and move residents in dangerous areas in advance to ensure the safety of people's lives and property.

Hello 2022 flood in the middle and lower reaches of the Yangtze River**Yes The meteorological department predicts that in 2022, the main flood season of the Yangtze River basin will be equal to drought and flood, with more precipitation in the upper and lower reaches and less in the middle reaches. Expert**, 5 In September, Anhui, Hunan, Hubei, and Jiangxi in the middle and lower reaches of the Yangtze River will be the main distribution areas of high temperatures. These places also showed signs last year because they were affected by La Niña, and they are areas with a high concentration of dry and hot weather.

In addition, because this year's Taijingcha has more windy weather than last year, and it has frequently landed in China's eastern coastal areas, it may cause rainy conditions in the middle and lower reaches of the Yangtze River basin in summer.

The No. 5 flood of the Yangtze River in 2020 was formed, and the flow rate of the Cuntan Station in the upper reaches of the Yangtze River rose to 50,900 cubic meters per second, meeting the flood numbering standard.

Affected by heavy rainfall, the Tuojiang River and Fujiang River, tributaries of the upper reaches of the Yangtze River, experienced over-protection floods, and the Minjiang River and the main stream of the Luzhou-Cuntan River section experienced over-warning floods. The flow rate of the Cuntan Station in the upper reaches of the Yangtze River rose to 50,900 cubic meters per second at 5 o'clock on August 14, meeting the flood numbering standard according to the "Regulations on the Numbering of Major Rivers in the Country".

The Hydrological Bureau of the Yangtze River Water Conservancy Commission of the Ministry of Water Resources officially released at 5 o'clock on August 14: "The No. 4 flood of the Yangtze River in 2020" was formed in the upper reaches of the Yangtze River, and it is expected that the peak flow of the Cuntan Station at Cuntan Station will be about 58,000 cubic meters per second on the evening of the 14th, and the maximum inflow of the Three Gorges Reservoir will be about 59,000 cubic meters per second at 8 o'clock on the 15th.
