How do you think that the Yangtze River has entered the main flood season, and there is a rare pheno

The Yangtze River has entered the main flood season, and there is a rare phenomenon of "reverse dryness in the flood season", which shows that the current environment is not very good, and we should pay attention to environmental protection in time.

This situation is still very rare, and it is because of the local high temperature weather that this situation will occur, and now the relevant departments should make corresponding adjustments to this situation to avoid causing more serious impacts, and may also lead to the subsequent development of the Yangtze River.

This is because this year's summer temperature in the country has created the highest temperature in nearly 100 years. Moreover, there was no rain in the rainy season in most parts of the south this year, which caused the Yangtze River to dry up when it entered the main flood season.

At present, the water level of the main stream of the Yangtze River, Dongting Lake and Poyang Lake has dropped to one meter compared with the same period last year, which is the lowest in the same period since the actual measurement record. At 8:00 on August 14, the water level of Jiujiang Station on the Yangtze River was meters. According to the meteorological forecast, most areas of the Yangtze River basin will remain hot and rainless in the coming week, and the water level in the middle and lower reaches of the Yangtze River will continue to drop by meters, which will have an adverse impact on shipping.

This represents a severe drought this year, and the rainfall is insufficient.

This year's drought situation is not optimistic. It was originally a flood season with frequent rainfall, but it suffered a rare drought, which is really not optimistic.

In many parts of the Yangtze River, there was a "flood season reversal", and local measures were taken to dredge the river channel and optimize the anchorage to ensure the safety of ships.

The flow of the main trunk of the Yangtze River has decreased by about 51% on average compared with the past five years, the water level of the main trunk of the Yangtze River has dropped by an average of meters, and the water level of many rivers has reached a record low. The scale of waterway maintenance of major rivers such as Xinzhou, Tuqiao, and Jiujiang has also dropped sharply, and the water level of the main trunk of the Yangtze River is close to the dry season of previous years.

The main river of the Yangtze River has completed 5.57 million cubic meters of dredging, completed 9,060 hours of dredging work, the current dredger is mainly shallow, after the shallow bag is removed, the overall water depth can be increased by three meters.

In addition, the waterway department has made a total of 5,014 voyages, with a voyage duration of 10,678 hours, a cruising mileage of 133648 kilometers, a waterway exploration of 9,616 kilometers, and 1,320 navigation beacon adjustments.

In the face of the declining water level of the Yangtze River, the Changhang Bureau quickly organized relevant departments, took a variety of measures, actively responded, strengthened waterway observation, optimized the configuration of navigation beacons, and dispatched a number of dredgers to station key rivers for dredging and maintenance day and night.

Strengthen the supervision of key waters, control the flow of ships in a scientific and orderly manner, strictly prevent ships from sailing beyond draft, and ensure the safe and smooth navigation of the Yangtze River.

The "reverse dryness during the flood season" will further reduce the anchorage area of the Yangtze River waterway, which will adversely affect the anchorage safety of ships.

The Huangshi Maritime Safety Bureau adopts the "tofu block" anchorage mode, divides the anchorage into small anchorage area and large ship anchorage area from top to bottom, and adopts information management methods such as "one library and one map" and electronic cruise to implement "one-to-one" publicity.

At the same time, through a variety of methods, the crew is informed of water changes, weather forecasts, etc., and the knowledge of high temperature fire prevention and drought emergency response is conveyed to the front line.

The Three Gorges Dam released 500 million cubic meters of water in advance to ensure the basic water level of the Yangtze River.

In the face of this situation, the local government should strengthen the prevention, control and management of this aspect, and also carry out the diversion of other rivers in the case of a significant drop in the water level to avoid more serious consequences.

In view of the continuous receding water level of the Yangtze River, the Changhang Bureau coordinated all units of the system in a timely manner, took multiple measures to effectively respond, strengthened the observation of waterways, optimized the distribution of navigation standards, dispatched a number of dredgers to be stationed in key waterways for dredging and maintenance day and night, strengthened the supervision of key waters, scientifically and orderly controlled the flow of ships, strictly prevented ships from sailing beyond draft, and ensured the safe and smooth navigation of the Yangtze River.

This year's flood season is estimated to be impossible to achieve in the summer, at least not until the rainy season in winter.

1. The Yangtze River's "flood season anti-drying" <>

The term seems a bit inappropriate this year, given that summer is also the time when some areas are sowing and maintaining agricultural growth. Summer is the rainy season, which is also what we call the flood season, but this year's flood season has seen the water level of the riverbed drop, and many places have dried up, which is the so-called dry weather. This unusual weather will naturally make us wonder where exactly we are going during the flood season, and at the same time we will think about the specific reasons for this, after all, the dry weather of this season still has a great impact on agricultural production.

Second, this year's flood season is gone, <>

According to the theory of inland internal circulation, if groundwater can evaporate the water vapor above the sky through a relatively normal temperature to form rain clouds, it will eventually rain, completing a perfect internal circulation of water vapor. This internal circulation is of course good for agricultural planting, and it is also conducive to the flood season of the Yangtze River, but the reality is that this year's weather is too hot, and the pressure on groundwater is too great, and there is no way to form cumulonimbus clouds in the sky.

3. This year's flood season may be <> when it will be rainy at the end of the year

According to the current amount of precipitation, the Yangtze River flood season can be said to be far away, not long ago we can just see that Poyang Lake has already grown grass in the lake, and now the water level of many sections of the Yangtze River is much lower than before, this situation must be affected by real weather factors, and the impact of global warming, which is the reality that we must recognize. According to this logic, this year's flood season may only be realized when it is more rainy at the end of the year, but it is undoubtedly not good to have more rain at that time, after all, it is not the time for planting at all.

There seems to be no flood season this year, and the Yangtze River basin has always been rainy, with the flood season generally running from May to October. This year, the water level of the Yangtze River continued to recede after entering the main flood season, and there was a rare phenomenon of "reverse drought during the flood season". This is due to the fact that the Yangtze River basin has significantly less rainfall, less water from the upper reaches of the river, and increased evaporation due to persistent high temperatures.

This year, there were abnormally high temperatures in various places, and the sun was shining during the rainy season, and the long period of high temperature weather caused the water level of the Yangtze River to drop seriously.

The water level of the Yangtze River has returned to a historic low during the flood season, but it is still several meters higher than that in the dry season in winter and spring, and water intake and water production have not been significantly affected.

Water is the source of life, if there is a shortage of water in life, it is very likely to affect their normal life, the Yangtze River as Wuhan is the main water, ** is deeply concerned by people, it is currently in the flood season, the Yangtze River is not as magnificent as in previous years, a large salary platform, a whole out of the water, a large area of tidal flats and water level traces on the bank, clearly visible, people can't help but wonder whether the Yangtze River in the flood season will affect the normal water use of residents.

What is the water level of the Yangtze River during the flood season?

On August 14, 2022, the water level of the Yangtze River was meters, which is equivalent to a drop in meters compared to the previous few days, and the water level in the Wuhan section of the Yangtze River is still slowly decreasing, which also makes people feel a certain amount of panic, but the person in charge of the local relevant departments immediately issued a statement saying that after the Yangtze River entered the main flood season this year, the water level continued to dry up in the flood season, which is related to the obvious lack of precipitation in the Yangtze River basin, the decrease in water from the upstream, and the increase in evaporation caused by continuous high temperatures.

Residential water is not directly affected?

After entering the summer, the water level of the Yangtze River hit a new low in the same period in the history of summer, but the water production of the waterworks has not been affected in any way, and the 12 waterworks belonging to the Wuhan Water Affairs Group have a daily water supply capacity of 4.9 million tons to fully meet the daily needs of residents, so the water level can be adjusted by the water intake height, so it is less affected by the water level.

What is my personal opinion?

I think that this phenomenon in the hot summer flood season is enough to make people think deeply, the relevant departments must carry out special inspections of the water supply pipe network of each water plant and the water supply facilities in the community, strengthen the inspection and maintenance of production equipment under high temperatures, increase the frequency of inspection of water and factory water in the raw water production process, ensure the safety of equipment operation from the source to the faucet, and ensure that the lives of the people are not affected.

This year's climate is very abnormal, many places have ushered in extreme high temperatures, and the water level of the Yangtze River has been declining, which has also had a great impact on the irrigation and domestic water of nearby residents.

The 12 waterworks owned by the group have a daily water supply capacity of 4.9 million tons, and the water intake of the water plants mainly adopts two methods: floating ship water intake and wellbore water intake. The pontoon boat takes water by means of a movable rocker arm connecting pipe to the ship, and the water intake height can be adjusted according to the water level. The water intake pipe of the wellbore is buried under water and is less affected by the water level.

At present, residential water use will not be affected for the time being, but if this is done for a long time, residential water consumption will be seriously affected.
