Geography + Humanities + New Knowledge = A new three-dimensional perspective on understanding the earth

According to the latest news from Euronews, southeastern France suffered heavy rainfall from Storm Monica on March 8-9 , bringing severe flooding to the Gard and Ardèche provinces. According to statistics, this rare heavy rain caused 48 Hourly rainfall exceeded 300 millimeters , causing numerous road flooding and vehicle overturning accidents

, leaving seven people missing. The fire and rescue department took emergency action to launch a large-scale search and rescue operation. This rare flood once again highlighted the hidden dangers of climate change on human safety. The storm swept Ardèche Rescue workers have carried out 35 rescue operations in the provinces and Gard

. At about 11:30 pm on the 9th, an ordinary family tragedy occurred in the village of Dion in the north of Nimes . This family of four wanted to take a car to their relatives’ home that night. Unexpectedly, it was a violent storm

And they drove to an old bridge that had been in disrepair by the Garden River. When they were about to cross, the water in the river had far exceeded the warning line. At this critical moment, the water suddenly overflowed and the old wooden bridge was split into pieces. Two capsized and fallen

Family members panicked in the overloaded car and only had time to utter a cry for help before the car drifted into the distance and disappeared. Firefighters were summoned and rushed to the scene in time using remote-controlled drones and thermal imaging cameras to search for dead bodies scattered across the river.

Amid the horrifying scene of vehicles, a middle-aged woman managed to survive and was rescued with injuries all over her body. However, her husband and two children were missing . The search and rescue team worked day and night to search every corner of the river. However,

As heavy rains resumed, the river swelled again and she survived. With little hope, nearly a hundred firefighters went into the water to search both sides of the river separately in order to rescue the missing people who may have suffered from hypothermia.

However, the water flow was too fast, and several people were almost swept away. They could only cling to the roots of towering trees or cliffs and look up at the distant river surface. Hoping for any clues,

The team members, who had worked hard all day and were completely soaked, still could not rest at night. At the same time, the 62-year-old mayor of Garnier, a

Small town in the northern Gard department, refused to listen to dissuasion and wanted to drive to the homes of relatives and friends far west of the town. Unexpectedly, as soon as he entered the bridge , a car was rushed down the river. Unexpected floods instantly swallowed up his off-road vehicle.

There was a scream in the car. In the end, only a Belgian tourist escaped death and was found sitting on a fallen linden tree by the river. He was sent to hospital to save his life , but the whereabouts of the village chief became the biggest suspense. On the 10th

, four helicopters carried firefighters and ambulance personnel to launch a large-scale search in various parts of the Gard province. Drones and police search and rescue dog teams were used to find clues about the whereabouts of the missing people , but heavy rains The water surge caused some roads and bridges to break,

Making rescue more difficult. This rare flash flood has caused many regions such as Aveyron, Lozère and Var to fall into a state of emergency with reservoirs overflowing . Thank you for liking, leaving a message and subscribing. And turn on the little bell for our daily updates. The government says

It has mobilized up to 250 firefighters, including water rescue crews, drones and dog teams. Helicopters provided by Civil Security have also been deployed. Firefighters in the Garde sector have carried out a total of 176 interventions. French Interior Minister Darmanin praised the brave efforts of rescue workers

But urged the public not to wade into the water easily or ignore driving safety. As the search continues, the lives and deaths of the seven missing people are uncertain, causing anxiety. This rare water disaster coincides with climate warming. The impact may restart the optimization work of France’s disaster prevention system. Météo-France said that

An orange alert for flooding in the Ardèche, Aveyron, Gard, Lozère and Var regions remained in effect on Sunday in the southwestern Charen-on-the-Sea. Deutsche and Gironde are under orange flood alert Why has France been hit by storms so many times in recent years? The reasons are complex.

First, France is located between Central Europe and the Mediterranean, between the temperate southwesterly flow and the equatorial anticyclone. It may be affected by storms from the Atlantic and the Mediterranean every year. France has long faced climate security risks from many aspects. Secondly, , France has a rich and diverse terrain,

From mountains and hills to vast plains and a 3,200-kilometer coastline. This has an impact on climate. The Alps and Pyrenees serve as natural barriers to the warm and humid air from the southwest. There is less precipitation in the eastern region; while the Mediterranean region of Belgium is adjacent to the ocean and

Is significantly affected by the Mediterranean climate , with hot and dry summers and mild and rainy winters. At the same time, France is located between the two most active cyclone activity areas in Europe from the Atlantic Ocean . The storm’s eastward movement is blocked in western and northern France;

The tropical moisture transported by the Mediterranean anticyclone will also trigger rainfall as the front cold air moves southward. As a result, France faces multi-directional storms from the Atlantic and the Mediterranean from northwest to southeast. The threat that cannot be ignored is that

France’s climate is also closely related to changes in sea surface temperatures in the North Atlantic. When the North Atlantic is in an extreme hot period , it will bring more frequent and lasting precipitation in France. On the contrary, although the sea surface in the North Atlantic is cooler

, it is still hot due to the active Arctic vortex. It may bring heavy rainfall to the northwest and north-central areas . More importantly, as global warming intensifies, extreme weather events are becoming more frequent in France. Heat waves and forest fires occur during summer droughts; heavy rainfall floods occur in winter.

Extreme natural disasters such as tornadoes continue to increase in spring. Among them, three severe storms between August and September 2017 were the most significant, causing heavy losses to various places. It is worth noting that human activities have also intensified the climate risks faced by France. The degree of urbanization is very high

. Water resources in some areas are over-exploited and water conservancy facilities are backward. Once extreme precipitation occurs, it is difficult to withstand floods. At the same time , economic growth promotes energy consumption and industrial emissions, forming a vicious cycle . France needs to find a convergence between

Responding to climate change and promoting sustainable development . Therefore, France As a hub country in southwestern Europe, it is located in a multi-directional climate impact zone and the superposition of human factors has been working hard to adapt to and manage climate risks from all latitudes in the future.

France can only strengthen infrastructure construction by guiding low-carbon transformation and deepen climate cooperation with neighboring countries. Only in this way can we truly build climate change resilience and achieve climate-safe development. In fact , floods often occur in France during storms. The reasons are complex,

First of all, terrain factors. The complex terrain of France, with its dense mountains on the east and west, prevents clouds and rain from advancing inland, and it is easy to form trapped precipitation . The northern plains are low-lying and have poor drainage conditions. Floods can easily accumulate

. Its southwest is bordered by the Atlantic Ocean, and its northeast is connected to the North Sea. It is easily affected by the ocean . Secondly, the soil type. French soil is highly water-containing and sticky

. It is easy to agglomerate in the dry season and is slow to absorb in the rainy season. In addition, the temperate monsoon The climate is very rainy in summer , and short-term heavy rainfall is difficult to penetrate into the ground in time, easily forming surface runoff and flooding.

More importantly, the hydrological characteristics are the most important. Most of France’s many rivers flow radially into the ocean, and the confluence speed is slow. In addition, the river channels are tortuous and have weak transport capacity. Coupled with extreme precipitation , rivers cannot carry too much rainwater and

Water levels rise rapidly, resulting in floods. What cannot be ignored is the difference in urban and rural construction . Some areas in France are highly urbanized. Water resources are overused. Reservoir storage capacity is tight. Some old embankments are of low standard and have poor carrying capacity. Extreme precipitation is under greater pressure.

Insufficient pollution prevention and control in rural areas has also aggravated the impact of floods. In addition, there are also global warming factors. Climate warming has led to an increase in extreme weather. Single-day precipitation has broken records , and the area of ​​heavy rainfall areas has also expanded.

Local precipitation intensity has become more intense. The test of soil absorption capacity is even greater. As a temperate transition region, France has undergone significant changes. The above natural and social conditions are superimposed on heavy rainfall weather. Many areas in France with unfavorable circulation conditions are difficult to discharge large amounts of precipitation quickly.

Rivers are unable to bear the load, and can only form large-scale floods. This also explains the fundamental reason why France frequently faces serious floods. At the same time, The French government is also actively adjusting prevention and control strategies , such as developing more sophisticated forecasting and early warning systems, strengthening reservoir dispatching capabilities

, repairing old hydrological facilities, updating urban and rural drainage systems, planting trees and disaster reduction, and other comprehensive management to build a safety and disaster prevention system that adapts to climate risks, which will benefit France’s future. To better cope with the impact of various floods,

There have always been various outstanding major flood events in the history of French storms. First of all, the flood in southern France in 1910 was the most destructive flood in France in modern times. In September 1910, a strong anticyclone formed in the northeastern Mediterranean, which

Caused Heavy rainfall brought to the south of France. The Rhone River basin received up to 900 millimeters of rainfall in 72 hours. The river water surged, causing flooding and destroying thousands of houses . Direct economic losses exceeded 300 million francs, and nearly 20,000 people died.

This was a devastating water disaster in the world at that time. Secondly, the 1959-1960 floods in southwestern France: From December 1959 to January 1960, there was continuous rainfall in the Garonne River, Aude River and other river basins for nearly a month , including rainfall in Toulouse from December 30 to January 2, 1960.

The water level of the Garonne River surged 10 meters, with a volume of up to 900 millimeters , causing flooding. Nearly 3 million people were affected, and 18,000 square kilometers of farmland were affected . Direct economic losses were close to 10 billion francs

. In 1999, a major flood also broke out in southern France: November 1999 From the 3rd to the 4th, a nearly 1,500-kilometer-wide heavy rainfall weather zone formed in the east of the Mediterranean Sea, which severely hit the southern French provinces

Of Aveyron. The total rainfall in Nimes in 72 hours was as high as 900 millimeters. Tens of thousands of homes were swallowed up by floods, and the disaster area reached 35,000 square meters. Direct economic losses of 23 billion francs per kilometer and 19 deaths

Were the second natural disaster in France in the 1990s. In addition, even more severe was the severe storm “Kamalu” in France in 2010: Strong West Antarctic on January 27-28, 2010 Front “Kamaru” swept across France, bringing extremely destructive winds with speeds exceeding 170 kilometers per hour and heavy rains. More than

2,000 square kilometers of forest were affected across the country. A rainfall of 202 millimeters west of Alphonseville in the northeast became the new local rainfall in 24 hours in January. Record direct economic losses of nearly 2 billion euros. Floods in southwestern France in 2014: In January 2014, heavy rainfall hit Agen

, Aveyron province in southwestern France for more than 10 days. Rainfall reached 700 millimeters . Water levels in major rivers jumped several meters. More than 4,000 people were injured. The forced evacuation of 15,700 hectares of farmland caused direct economic losses of approximately 1.5 billion euros. Since the 1990s, as global warming has intensified,

France’s annual average temperature has continued to rise. Extreme weather events have increased significantly, according to long-term monitoring data from the French Meteorological Office and the Hydrological Office. Statistical analysis shows that the frequency of extreme precipitation events has increased significantly.

From 1990 to 1999, an extreme precipitation event occurred in France once every 5 years. However, since the 21st century, this cycle has been significantly shortened to every 3-4 years. The number of extreme precipitation events in a single day has also continued. The average regional rainfall intensity has increased significantly

After updating the historical record. Secondly, the scope of heavy rainfall has expanded unprecedentedly . In the 1990s, the Mediterranean coast of southern France was the summer peak area of ​​rainfall intensity. However, in the early 21st century, the area of ​​heavy rainfall has expanded to the entire central and eastern France

For extreme precipitation events. The affected area is also increasing . At the same time, the frequency of flood disasters has increased significantly. From 1998 to 2017, for example, an average of 4-5 moderate to severe floods occurred every year, which is 2-3 times that of the same period in the 20th century.

Many major rivers such as the Rhone River The 100-year flood standard for the Garonne River and the Garonne River is no longer able to meet actual needs . What cannot be ignored is that

The peak flow and water levels continue to hit new highs. In recent years, the maximum peak flow and water levels have repeatedly occurred in some areas, which poses new challenges to the capacity of flood control facilities.

For example, In June 2016, the discharge of the Saône River hit a record high in 72 years. Disaster economic losses showed a geometric cumulative trend. Calculated by superimposing each year , the total flood losses in France from 1998 to 2017 exceeded 35 billion euros. Single-year losses were also growing steadily.

In 2016, the Garonne River Basin caused A loss of up to 800 million euros . Generally speaking, you must cross a hanging river, but there are countless dangers hidden in navigation on the river. If you need to drive across the river during a flood, you must be especially careful. First,

You need to understand the current situation of the river water level and flow speed to decide whether it is necessary to take action to cross the river. Avoid being convinced. Falling into danger due to false news. The local hydrological department usually issues timely water warnings, which are worthy of attention

. Secondly, when choosing a river crossing route, you need to be careful to avoid bends in the river to avoid being more susceptible to whirlpools; there should be a wide enough evacuation zone next to it in case of vehicle accidents. If you lose control, you can quickly evacuate

The crossing point. The roads on both sides should be clear. At the same time, the vehicle should be as light as possible to avoid heavy vehicles taking risks. Check the vehicle suspension system and brake properly. Before crossing the river, you need to unload the vehicle’s excess items to reduce the weight

. The wheels need to be inflated to prevent accidents. Drifting in the water cannot be ignored. When crossing a river, keep the speed slow and do not ride on the wind and waves . If you encounter strong convective currents, it is safer to drive sideways facing the current .

When the water depth and flow speed change, you need to adjust the speed and route in time . In severe cases, it is important to stop and wait for changes . During the process of crossing the river , the driver should concentrate on driving and never be distracted by

Other passengers. It is necessary to firmly hold on to reduce the shock of the body’s center of gravity . It is also necessary to carry emergency life-saving equipment such as emergency life ropes with you

. In short, you must remain vigilant and calm at any time and at any time when crossing the river. Once discovered, You must decide to stop and avoid any danger signs. Never waste time and risk moving forward. This will be the first principle to protect your own safety. After a flood occurs,

Special attention must be paid to some details and methods in rescue . First, it is necessary to assess the disaster situation and collect data from multiple sources. If there is no Accurately delineate the scope and extent of the disaster through human-machine images, satellite remote sensing, etc.,

And identify hidden danger points such as possible delta flood areas based on topography, hydrology and other factors . Evaluate the difficulty of life safety in different areas and identify key search and rescue targets. Secondly, mobilize elite rescuers. Strengthen the establishment of a rescue headquarters, clarify the division of labor among local departments, and

Deploy professional teams such as diving search and rescue teams. Organize militia groups and mass volunteer teams to provide backup support , such as adding communication contact points, participating in material distribution, and other auxiliary work. At the same time, it is necessary to ensure that The rescue team safely

Plans effective entry and evacuation routes into the disaster area, constructs risk avoidance measures, such as reinforcing temporary turbulent crossings, trains rescuers on disaster prevention knowledge and equipment usage, and equips them with appropriate waterproof escape suits, life jackets, ropes, etc., and closely monitors hidden dangers in changes in water conditions.

In addition, it is necessary to accurately direct the search and rescue, and adopt a flute-shaped search method from near to far after clearing the obstacle area, organize regular search summaries, and timely adjust the strategy. We should use volunteers and local personnel’s clues to accurately locate the wandering range near each disaster point.

What is overlooked is that it is necessary to set up temporary refugee areas, choose areas with less severe disasters, set up multiple refugee shelters, set up separate areas for people with different needs, purchase or allocate sufficient daily necessities and epidemic prevention supplies in a timely manner,

Establish simple water supply and power supply facilities, and pay attention to refugee safety and epidemic prevention management. It is important to carry out comprehensive epidemic monitoring and prevention work and regularly disinfect and sterilize the environment in refugee areas. Monitor the safety of drinking water, keep records of refugee health management,

And strengthen surveillance and early warning of infectious diseases
