As the No. 3 flood of the Yangtze River forms upstream, how should the upstream residents be relocat

Since July, the Yangtze River basin has been flooded continuously due to heavy rainfall. July 2nd,"Yangtze River No. 1 flood"formed in the upper reaches of the Yangtze River; For now"Yangtze River No. 2 flood"Still wanton"Prestige", and it is worth noting that the Yangtze River No. 3 flood is forming upstream.

According to experts, this year's floods in the Yangtze River basin are characterized by continuous and almost no intermittent characteristics, which is very terrifying. And according to the Meteorological Bureau, there will still be heavy rainfall in the Yangtze River basin in late July and August, so further flooding in the Yangtze River basin is still possible.

The dangers of the flood must be well known to everyone, not only will they tear down houses, but the huge currents will wash people away. If people are caught up in the flood and are not rescued in time, the possibility of an increase is very high. So in"Yangtze River No. 3 flood"Before it is completely formed, the relevant departments should move the residents in a timely manner and face it with perfect preparation"Yangtze River No. 3 flood"。

So how should the relevant authorities move residents in a timely manner?

It is believed that the local residents know how harmful the flood is, and they have experienced it"Yangtze River No. 1"Floods and"Yangtze River No. 2 flood"After that, the local residents will definitely actively cooperate with the transfer of the relevant departments. Therefore, the persuasion steps of the residents can be omitted at this time. At this time, the relevant authorities should first find a temporary shelter for the residents on high ground, and then build temporary shelters for the residents.

In addition, it is necessary to prepare sufficient food and daily necessities so that the residents do not suffer from hunger. Then it is necessary to settle the residents and give them enough comfort so that they can calm their minds and not feel the fear and panic caused by the flood.

Then, in the low-lying area around the shelter, it is necessary to use sandbags or water barriers to waterproof, or build waterproof thresholds and set up retaining dams to prevent floodwaters from entering the temporary shelter.

The No. 3 flood of the Yangtze River is formed in the upper reaches, and its upstream residents should stay away from the vicinity of the flood, go about their lives with peace of mind, and do not panic, they will be safe!

Residents in the upper reaches were evacuated and evacuated in a timely manner under the advance notification and early warning, and the relevant departments coordinated with the People's Army. Electricity is definitely no longer available, and can only be transported by land or air.

Residents of the upper reaches should move quickly to the surrounding provinces, and remember not to put their lives at risk due to greed for money.

Upstream residents should obey the arrangement of **, move to a safe place, and at the same time transfer their property to minimize the loss.

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.

1 The cold and high-pressure air masses in the north generally meet the warm high-pressure air masses in the south in the middle and lower reaches of the Yangtze River, and the quasi-stationary front stays here for a long time, and the precipitation in this area is large.

2 There are many lakes and rivers in the middle and lower reaches of the Yangtze River, so they are prone to flooding.

There is a significant rainfall process in the upper reaches of the Yangtze River and the upper reaches of the Han River. Drought has eased in parts of the Yangtze River basin due to rainfall, but water levels in the middle and lower reaches of the Yangtze River continue to fall. In the coming week, rain will continue in the upper reaches of the Yangtze River, with a total of 30-50 mm of rain in the middle and lower reaches of the Jinsha River and Yalong River.

There was no significant rainfall process in the middle and lower reaches of the Yangtze River. Typhoon No. 11 is expected to remain a super typhoon this year, but it will not have a direct impact on the Yangtze River basin. While recent rains have eased drought in some areas, much of the middle and lower reaches of the Yangtze River still have no effective rainfall.

The water level in the middle and lower reaches of the main stream is significantly lower than the historical water level. All departments and units should maintain a high degree of vigilance, strengthen bottom-line thinking, and do a good job in flood prevention and drought control.

Pay close attention to changes in water, rain, drought and flood conditions in the basin, roll forecasts and forecasts, and strengthen analysis and judgment; Strengthen communication and coordination with the power sector and provinces and cities in the basin, and coordinate the relationship between water storage, power generation and water supply; We will further improve the dispatching plan for key reservoirs in the lower reaches of the Jinsha River, such as cascade reservoirs, the Three Gorges Reservoir, and the Danjiangkou Reservoir, and give full play to the comprehensive benefits of reservoir groups. The water level from the upper reaches of the Yangtze River to the lower reaches of the port showed a downward trend. Therefore, at the same time, from the water level, Wuhan should be higher than Nanjing.

Water level is an important hydrological data, and water transportation, flood control, ports and other departments have to measure the water level every day.

The water level of the Yangtze River during the flood season is of great value for flood control and flood control. Between the Liuzhou Yangtze River Bridge and the Wuhan Yangsigang Yangtze River Bridge, nearly two kilometers of stone roads are exposed to the water. The stone road was built during the construction of the Parrot Island Bridge.

The river has recently dried up and "surfaced". A slender "road" appeared in the river ** between the Liuzhou Bridge and the Yangsigang Bridge in Wuhan. It divides the Yangtze River waterway into two kilometers, with several forks along the way.

This is a T-shaped dam for the waterway improvement construction, which was built for the Parrot Island Bridge. Due to the wide nature of the nearby river, the dam acts as a binding water in order to concentrate the water for navigation. Its function is to regulate the waterway and optimize the navigation environment.

Due to the recent drop in water levels in the Wuhan section of the Yangtze River, the building is partially exposed to river water.

At present, the drought situation in the upper reaches of the Yangtze River has been alleviated, but there is still no effective rainfall in most areas of the middle and lower reaches of the Yangtze River, the water level of the main stream in the middle and lower reaches is much lower than that of the same period in history, the reservoirs in the upper and middle reaches have a large amount of water to be stored, and the situation of flood and drought disaster prevention is still complex and severe.

Affected by rainfall, the drought situation in some areas of the Yangtze River basin has eased, but the water level in the middle and lower reaches of the Yangtze River continues to recede. It can be said that although the recent rainfall has alleviated the drought in some areas, there is still no effective rainfall in most areas of the middle and lower reaches of the Yangtze River, the water level of the main stream in the middle and lower reaches is much lower than that in the same period in history, the reservoir groups in the upper and middle reaches have a large amount of water to be stored, and the situation of flood and drought disaster prevention is still complex and severe.

Due to the rainfall, the drought in some areas of the Yangtze River basin has eased, but the water level in the middle and lower reaches of the Yangtze River continues to recede.

The frequent occurrence of floods in the middle and lower reaches of the Yangtze River is caused by the comprehensive action of various factors, and biological measures, engineering measures, agricultural production measures, policy measures, and technical measures should be adopted for comprehensive treatment.

1) Biological measures: The construction of shelterbelts in the middle and upper reaches of the Yangtze River can reduce soil erosion in the upper reaches of the Yangtze River, reduce the surface runoff in the upper reaches of the Yangtze River, and reduce the amount of water flowing into the main stream of the Yangtze River during the flood season.

2) Engineering measures: including the construction of the Three Gorges Dam, cutting and straightening the Jingjiang River section, reinforcing the embankment in the middle and lower reaches of the Yangtze River, and building flood diversion and flood storage projects. The Three Gorges Reservoir can impound and store water from the upstream to reduce the pressure on flood control in the middle and lower reaches. The Jingjiang River can be straightened so that the water of the Yangtze River can be discharged more smoothly; Reinforcing river embankments can prevent embankments from collapsing and flooding; Flood diversion and flood storage projects can reduce the flood control pressure in the lower reaches of the Yangtze River.

3) Policies and measures: prohibit steep slope land reclamation; It is necessary to return farmland to forests and lakes, and to develop forestry and animal husbandry in hilly areas according to local conditions; Ecological migration if necessary. Measures should be taken to manage the existing forests in the middle and upper reaches of the Yangtze River, and the destruction of forests is strictly prohibited.

4) Agricultural production: Adapt measures to local conditions, rationally develop agriculture, pay attention to the development of diversified agriculture, and prevent soil erosion in hilly areas.

5) Technical measures: establish an early warning system for flood disasters; We should use modern high-tech means to strengthen the monitoring of the water situation in the Yangtze River basin and make timely forecasts.
