There will be another flood in the upper reaches of the Yangtze River, how to save yourself in the f

You should stay away from the flood immediately, and if you are washed away by the flood, you should see if there are any tools around you that you can grasp and swim slowly to the shore.

In the event of a flood, you can save yourself in the event of a flood

1.Evacuate the flooded area and take shelter in a safe area. If you are unable to evacuate, you need to move to a higher place and call 110 Ambulance** to wait for rescue.

2.Keep away from hazardous areas such as high-voltage routes and power equipment.

3.If you have been caught in a flood, try to grab something that can be fixed or float, such as a bed board or a door that can be used as a raft, and look for a chance to survive.

When running for your life, don't think about some of your family's finances, it's important to run for your life. Then you have to flee to a higher and more solid place, and you can also choose some flotation tools in the water.

Calm and calm, you can run to a high place, if you accidentally fall into the water, you must find a floating object to save yourself.

The weather conditions in the middle reaches of the Yangtze River that are prone to major floods mainly include the following:

Heavy rainfall: During the flood season, the middle reaches of the Yangtze River are susceptible to concentrated heavy rainfall, which causes a rapid increase in river runoff in a short period of time, resulting in flooding.

Typhoons: In summer, typhoons can have a severe impact on the middle reaches of the Yangtze River, bringing strong winds and torrential rains, leading to flooding.

Snow and ice melting: In winter, due to frequent cold spells, the ice and snow in the middle reaches of the Yangtze River may melt, leading to an increase in river runoff, which can trigger flooding.

Mudslides: In mountainous areas, natural disasters such as mudslides can occur due to heavy rains or melting snow and ice, which can affect river flows and flooding.

It should be noted that in addition to the above-mentioned weather conditions, other factors can also lead to flooding in the middle reaches of the Yangtze River, such as the release of water from upstream reservoirs and poor river channel management. Therefore, we need to pay close attention to the changes in various factors and take timely measures to reduce the damage caused by flooding.

Because flood disasters and rain and flood disasters often occur in the same area at the same time or consecutively, it is sometimes difficult to define them accurately, and they are often collectively referred to as flood disasters. Floods occur in many places, and they are also a very destructive disaster. Do you know the causes of the flooding of the Yangtze River?

I'll introduce it to you today, and if you don't know, take a look!

Causes of flooding in the Yangtze River.

The human factor. First, soil erosion and a large amount of sediment accumulation in the middle and upper areas have caused the riverbed to be raised and the riverbed's passing capacity to be reduced. The second is the destruction of accommodating capacity.

During the flood season, excess floods, especially floods with excess capacity, cannot effectively accommodate the flooding hazards. The third is the destruction of flood control capacity. It is mainly manifested in the elevation of the riverbed and the increase of obstacles in the riverbed.

Generally speaking, water conservancy facilities have an obstacle effect, and the large and small bridges along the main and tributaries of the Yangtze River basically have an adverse impact on flood flow.

Natural factors. Naturally, the reason for the frequent occurrence of flood disasters in the Yangtze River basin is abnormal, that is, the rainfall is particularly large, the intensity is particularly strong, and the scope is particularly extensive. Whether or not a flood disaster occurs in the Yangtze River basin depends on three factors:

One is the rainy season; the second is typhoon rain; The third is the warm and humid airflow from the southwest. From the actual situation in the middle and upper reaches of the Yangtze River, it is mainly caused by the abnormal plum rain, and the typhoon surge of the middle and lower reaches, especially in the lower reaches of the Yangtze River, has a considerable impact on it. The southwest warm and humid airflow has a certain relationship with the plum rain, but its abnormal situation is caused by the non-plum rainy season, such as floods and mudslides in western Hubei Province.

In the event of a flood disaster, the drinking water source should be selected in the upstream of the flood or in the less polluted water area in the waterlogged area, and a certain range should be demarcated, and Qi Stufffan is strictly prohibited from discharging feces, sewage and garbage in this area. In areas where conditions permit, it is advisable to set up wharves at water intake points so that water can be taken at a certain distance from the shore.

It's basically man-made. In addition to the river itself, there is also a large area around the river that belongs to the river basin, which is used to store and replenish water, and now the river basin is destroyed, so the precipitation is small and there is no water, and when the precipitation is large, there will be floods.

And it can't simply be thought that floods are always unfavorable, many rivers will flood in the rainy season, replenishing water and nutrients to the areas it floods, usually those places should belong to the rivers, so the annual regular floods are not only not unfavorable, but conducive to the growth of the natural environment and wild animals, but now people occupy the territory of the rivers, but to blame the flooding of the rivers.

Therefore, the flooding of the Yangtze River can be considered to be caused by man-made disasters. In order to avoid this situation, the local people and residents should no longer enclose the lake to make land, destroy vegetation and pollute the environment for some small profits.

The causes of the Yangtze River's flooding can be roughly divided into natural causes and man-made causes. The natural cause is primary, and the cause is secondary.

A natural cause:

The flooding of the Yangtze River is mainly due to the large amount of flood in the upstream main stream and the middle reaches of the tributaries, the lack of sufficient flood control and detention sites in the middle reaches, and the insufficient cathartic capacity of the river. Most of the areas through which the Yangtze River flows are humid areas, with a wide basin area, many tributaries, long flood seasons and large amounts of water in the main stream, and floods are formed by heavy rainfall. In some years, (mainly related to the strength of the monsoon) heavy rainfall in the basin, the north and south tributaries come at the same time, especially the flood in the upper reaches of the Sichuan River, and multiple floods are encountered at the same time, and the main stream of the Yangtze River will inevitably have a major flood.

b Human reasons:

Due to excessive logging, steep slopes have been cleared, surface vegetation has been greatly reduced, and soil erosion has intensified, which has reduced the ability of the river basin to regulate runoff, reduce peak shaving and replenish dryness, and cause a large amount of sediment to flow into the river, resulting in the riverbed being too high and the river channeling capacity being reduced. In addition, the enclosure of the lake and the cultivation of farmland have caused the lake to shrink, and the ability to regulate and store flood peaks has been greatly weakened.
