Will the largest flood since the start of this year s flood season reach the Three Gorges Hub?

Since the beginning of the flood season this year, the largest flood has reached the Three Gorges, and I don't think it will have much impact on the Three Gorges hub. China's Three Gorges Dam is the world's largest concrete gravity dam, is the world's largest comprehensive benefit of the water conservancy hub, the Three Gorges is "China's industrial reform and opening up 30 years of the most influential 30 major events.""One. Due to the impact of heavy rainfall, "the No. 2 flood of 2020 on the Yangtze River formed in the upper reaches of the Yangtze River on the 17th, and when the flood arrived, the Three Gorges Hub operated smoothly.

At 11 o'clock on the 18th, a Xinhuanet reporter saw at the top of the Three Gorges Dam that the Three Gorges Hub opened three deep flood discharge holes for flood discharge, and three huge streams of water gushed out. The monitoring records of the operation department of the Three Gorges Hub show that the main parameters of the dam such as displacement, seepage and deformation are within the normal range, and the safety indicators of the dam's water-retaining buildings are stable.

Ancient people used their wisdom to build dams to maintain the small peasant economy, promote the development of agriculture, increase the yield of land, protect farmland from infringement, after the construction of ancient water conservancy projects, a large number of farmland can get sufficient water sources, which is the fundamental guarantee of grain production. Like Lingqu, Dujiangyan and so on are famous water conservancy projects, among which the Dujiangyan project is still playing a huge role in protecting our homeland. <>

On 18 July, the flood control rate of the Three Gorges of the Yangtze River exceeded 45 percent, and while the flood water was impounded, the Three Gorges Hub also actively brought into play the benefits of power generation, with 32 giant hydro turbine units working day and night to transform the rolling flood water into a steady stream of electricity needed by the people in their daily lives, and their power generation rate reached full capacity, with an average daily power generation of 100 million kilowatt hours. <>

According to the preliminary ** of the Three Gorges Ladder Diversion Center of the China Three Gorges Corporation, this round of floods will slowly recede after reaching its peak on the 18th, but the Three Gorges Reservoir may usher in a new round of flooding around the 21st. However, I believe that the Three Gorges Hub will protect our common home and protect our southern Yangtze River basin from infringement.

The biggest flood has a certain impact on the Three Gorges Hub, and this time the flood is very violent, and the impact of the flood will have an impact on the dam of the Three Gorges Hub.

The largest flood since the beginning of the flood this year has reached the Three Gorges, which will not affect the Three Gorges Hub, and the Three Gorges will continue to operate normally and continue to generate electricity!

I don't think the impact will be very big, but the nearby residents will definitely have a sense of fear, but the bigger the flood, the stronger the state will definitely protect the Three Gorges Hub.

Yes, the flood peak has a great impact, and the storage of water will also put a lot of pressure on the reservoir dam, so it is time to test the construction strength of the Three Gorges Project.

The Three Gorges has been discharging flood water since early July, but the amount of water discharged is determined based on the capacity of the downstream river and the amount of water coming from the upstream. Sometimes 40,000 cubic meters, sometimes more than 30,000 cubic meters. The Three Gorges staggered the peak of mid-July to leave some of the flood water in the Three Gorges Reservoir before it was discharged, so the discharge is expected to continue until late August, or even longer.

8 provinces. They are Hubei, Hunan, Shanghai, Jiangxi, Jiangsu, Anhui, Chongqing, Sichuan.

The Xiling Gorge section of the Yangtze River and the Gezhouba Hydropower Station downstream of Yichang City, Hubei Province constitute a cascade power station. The Three Gorges Dam is the world's largest hydropower station and the largest engineering project ever built in China. However, due to many problems such as relocation and the environment, it has been accompanied by huge controversy from the beginning of preparation.

The Three Gorges Hydropower Station has more than 10 functions such as shipping, power generation, and planting. In 1992, the National People's Congress approved the construction of the Three Gorges Hydropower Station. Construction began in 1994, started on the afternoon of June 1, 2003, and was completed in 2009.

The entire middle and lower reaches of the Yangtze River! China will set back 100 years!

Influential.

Most of the rivers or tributaries in the Yangtze River basin have limited water carrying capacity and cannot discharge water during the flood season in a short period of time, which can lead to flooding.

The purpose of the Three Gorges Dam is to allow the Three Gorges Dam to collect water from the upper reaches of the Yangtze River during the flood season, which is equivalent to intercepting the peak flood and preventing the flood from threatening the middle and lower reaches of the Yangtze River.

There is more water in the upper reaches and more water in the downstream.

However, since it is a flood discharge, it must be controlled and will not affect the normal economic life of the downstream.

Impact, flood discharge is a lot of mechanical energy, and its gravitational potential energy is converted into kinetic energy, which has a great impact force.

The impact of the Three Gorges Dam flood discharge on the downstream is mainly in the following aspects:

1.More water will increase: The Three Gorges Dam will open the floodgates to release floodwater, which will increase the amount of water coming from downstream areas, increasing the amount of floodwater.

2.Water quality impact: Flood discharge will lead to an increase in nutrients and sediments in the downstream river sections, which may have a certain impact on water quality.

3.Riverbed erosion and alteration: Flood discharge will accelerate the flow velocity of the downstream river section, resulting in riverbed erosion and alteration, affecting the riverbed shape and return and river ecology.

4.Increased flood control: If the discharge flow is too large, it may increase the downstream flood control pressure, leading to an increased risk of flooding.

In general, the impact of the Three Gorges Dam flood discharge on the downstream is complex and multifaceted, and various factors need to be considered comprehensively and corresponding measures should be taken to manage and protect them.

Recently, the Three Gorges Dam in the Yichang region of Hubei Province has opened two deep Kai Biao holes to increase flood discharge, and the amount of water discharged from the reservoir has increased from about 10,000 cubic meters per second to 10,000 cubic meters per second.

This has caused many people to worry about whether the discharge of the Three Gorges flood will lead to flooding in the lower reaches of the Three Gorges.

The principle of the Three Gorges Dam flood discharge is simply that the total height of the Three Gorges Dam is 185 meters, but the maximum water storage height of the flood during the flood season is 175 meters, and the water level is 145 meters in normal times.

In the past month, the Yangtze River basin has been hit by heavy rainfall, which has caused the water level of the Three Gorges Dam to reach meters, exceeding the normal storage level. In order to drain the excess water, the Three Gorges has recently started to discharge floodwater, but the flow rate is 10,000 cubic meters per second, which is within the normal carrying range of the downstream river and will not affect the downstream.

The reason why we chose to release the flood now is because it is not the peak flood season. In addition, in the next few days, the Yangtze River basin will be short or usher in a new round of precipitation, and the flood discharge at this time will help to free up the storage capacity and prepare for the next collection of flood peaks.
