Can the entire embankment of the Yangtze River be raised or the river surface opened up to completel

Floods are a disaster or a problem that the Chinese have always faced us, after all, humans used to live on both sides of the Yangtze River or the Yellow River basin, which we call the mother river. However, due to the over-exploitation or over-drinking of the Yangtze River water in recent years, various serious flood disasters have occurred in many areas, especially this year, when the rain is too concentrated, and the flood disasters are even more serious. If the Yangtze River embankment is raised or opened up, can the flood problem of the Yangtze River be completely solved?

Not necessarily. The main reasons for this are as follows. <>

1. The water storage area of the lakes in the tributaries of the Yangtze River has been greatly reduced. First of all, the first point is about the lakes in the Yangtze River basin, and their water storage area has been greatly reduced, which is the main reason for the flood disasters in the middle and lower reaches of the Yangtze River in recent years. After all, if the tributaries of the Yangtze River can maintain a relatively stable state, in the past, they were all due to the lakes, which can help the tributaries of the Yangtze River to carry out a certain amount of flood control and irrigation and water storage.

However, due to a large number of people enclosing the lake and cultivating land in recent years, the area of the lake has been greatly reduced, especially the Dongting Lake in Hunan Province, which we know, has decreased by 1 3 compared with before, and its water storage area has also dropped by about 30%. <>

2. River sediment in the Yangtze River Basin. Secondly, considering that there is still a lot of sediment in the Yangtze River basin, if we widen the embankment and lake again, if the sediment accumulates for a long time, the water level will still rise, then it is still a symptom rather than a cure, so the widening of the river can only be carried out in the short term to help alleviate the flood disaster. <>

3. Raise the Yangtze River embankment. The last point is that although one of the goals and intentions of raising the Yangtze River dam is good, it is also an unworkable way to fundamentally alleviate the water level of the rivers within the Yangtze River. After all, one of the flows of the Yangtze River is the third largest river in the world, and its flow is far greater than we imagined.

All science and technology are for human beings, not for nature.

This is a valuable experience in water control since ancient times, not to mention the time-consuming, laborious and costly to add dams and open water surfaces, if it is transported to the upstream and downstream rainstorms, it is impossible to stop the flood.

No, because the forces of nature cannot be resisted by man, and if the entire embankment is built, it may cause the embankment to burst during the flood season, and widening the river surface is also a symptom rather than a cure.

It can't be solved, if you encounter extreme rainstorms, you can't withstand God's precipitation just by relying on man-made open embankments.

OK. Because the Yangtze River embankment is rebuilt as a whole, or the river surface is opened, the flood water can be well guided to flow into the sea, so the Yangtze River flood problem can be completely solved.

Most of the sediment in the Yangtze River should stay in front of the dam, and I don't know how experts will solve it later. When the flood came, the reservoir was not impounded; When water is scarce, the dam needs to ensure power generation without releasing water. The knowledge of scientific use can be very deep.

Because the sediment is trapped by the dam, it is deposited at the bottom of the dam, resulting in a decrease in the amount of sediment downstream. On the one hand, the upstream will raise the water level of the river, and the Yangtze River will gradually become a hanging river on the ground like the Yellow River.

Causes of flooding in the Yangtze River:

1. The river basin is wide, there are many tributaries, the precipitation is abundant, the main stream flood season is long, the water volume is large 2, the river channel is bent, the sediment is silted, and the flow is not smooth.

3. Enclose the lake and make fields.

4. Indiscriminate felling in the middle and upper reaches, and serious soil erosion.

Workaround:1Upstream: Soil and water conservation forests in the middle and upper reaches of the Yangtze River; Construction of reservoirs 2Midstream: focus on renovating the Jingjiang River section, cutting the bend and straightening it; returning farmland to lakes; Construction of reservoirs and flood diversion and storage projects.

3.Downstream: Reinforcement of river embankments; Dredging of river channels.

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.

At about 5 o'clock in the morning on November 8, the 15th to 16th groups of groups of Guide Village, Sanmao Street, Yangzhong City, Zhenjiang, Jiangsu Province were found to be in danger of collapsing the river, with the main embankment of the collapsed river about 240 meters and a depth of about 150 meters. After the danger occurred, the local ** organization personnel rushed to the scene to carry out the rescue, there is no personnel **, the newly built embankment has been closed, and the rescue work is still in progress.

Through **, I saw that a large row of neat trees and a building standing by the river were swept away and swallowed up in an instant after the river embankment collapsed. As of 10 a.m. that day, about 300 villagers from 75 households in the vicinity of the danger had been completely evacuated.

According to the analysis of experts, the collapse of the river embankment was mainly caused by the change of the water flow of the Yangtze River in this section and the erosion of the river.

In addition, Sanmao Street urgently transferred nearly 200 militiamen from various villages to the scene to participate in the embankment work, and hundreds of militia rescue personnel from other towns and districts also participated in the construction of the embankment. So far, about 1,500 meters of newly built embankments have been closed before the late tide rises.

Reasons: 1. There are many plains in the middle and lower reaches, and the terrain is low and flat, which is not conducive to flood 2. It belongs to the monsoon climate, with a lot of precipitation and concentration, and there are many heavy rains in summer 3.

4. The upstream area has serious damage to vegetation, resulting in soil erosion, and the downstream riverbed is raised, and sediment is silted up, forming an above-ground river (the Jingjiang River section is particularly prominent, known as the "Jiuqu Ileum").

5. People have enclosed the lake to create fields, which has reduced the area of the lake, and the ability of the lake to regulate and store floods has been weakened: 1. Strengthen the upstream soil and water conservation work, and plant more trees and afforestation 2. "Cut off the bay and straighten" the middle reaches of the river, and dredge the river.

3. Downstream construction of water conservancy projects (reinforcement of flood control embankments, construction of reservoirs) 4. Improve people's awareness of flood prevention and self-rescue ability.

There are many ways to do it, depending on how you do it.

In the upper reaches of the Yangtze River, a shelterbelt system should be established in the middle and upper reaches of the Yangtze River to conserve water sources and prevent soil erosion.

Flood control and power generation projects (such as the Three Gorges) should be built in areas with abundant hydropower resources in the middle and upper reaches.

Here's what you can look for online, see if there's one you can use.

The plains and hills on both sides of the middle and lower reaches of the Yangtze River are at low altitudes, the cold and warm air moves from north to south are unhindered, the East Asian monsoon activity is very obvious, and the climate has four distinct seasons. The characteristics of the river channel are sometimes bundled and released, the shape is similar to the lotus root, and the open river section has many heart beach outcrops, and the river channel is divided. There are more than 3,100 kilometers of dry embankments on both sides of the middle and lower reaches of the Yangtze River.

Tens of thousands of kilometers of embankments and sea ponds have been built, and 40 large and small flood storage areas have been built to alleviate the threat of flooding. By the end of 1992, 450,000 large, medium, and small reservoirs had been built, with a total storage capacity of nearly 140 billion cubic meters, bringing into play the comprehensive benefits of flood control, power generation, irrigation, and aquaculture.

Construction of reservoir dams, afforestation.
