The flood in Western and Central Europe in 2021 is a natural disaster with severe floods in several river areas in Switzerland , Germany and other countries in the summer of 2021. The related natural events were triggered by the storm "Bernd" after a week-long period with many storms and precipitation .

Since the beginning of July 2021, influenced by a strong wind band of the jet stream shifted far south, warm stormy winds from France and Piedmont and a cool wind current from the north have reached Central Europe . This resulted in a stable expanded zone with severe thunderstorms , hail and heavy continuous rain over the north-western Switzerland , the Ticino , eastern Belgium , North Rhine-Westphalia , Rhineland-Palatinate , Baden-Wuerttemberg and Bavaria . As a result, lakes, rivers and streams were flooded in many places , and ultimately considerable property damage and personal injury. The water levels of some bodies of water reached high levels similar to those of the flood of the century in 2005 and the flood of 2007 or even exceeded them. The flood was particularly devastating in the Eifel , where towns were devastated and many people lost their lives.

backgrounds

causes

Even if a direct assignment of individual events is difficult, the climate researchers Stefan Rahmstorf and Friederike Otto named global warming as an essential factor for floods : For example, warmer air can transport more water vapor (the atmosphere can absorb approx. 7% more water with every degree Celsius warming ), which then rains down. Global warming therefore increases both the frequency and the intensity of extreme weather events such as heavy precipitation . This is shown by historical observations and climate projections, as well as fundamental knowledge of physics. In addition, climate change triggers a weakening of the jet stream , which in turn means that weather conditions such as highs and lows remain largely in the same place for a long time instead of moving on. This exacerbates their regional effects, for example heavy rain events or the drought in North America . But the soil sealing and deforestation and parched soils contribute to the dramatic consequences of the precipitation.

prehistory

While heat and drought prevailed in 2018 and 2019 ( drought and heat in Europe in 2018 and heat waves in Europe in 2019 ), the first floods occurred in the affected areas at the beginning of 2021: for example, the Rhine overflowed its banks in January and February . In the months of May and June, weather conditions determined by low pressure on the northern edge of the Alps had repeatedly led to continuous rain . Several times, especially in the catchment area of ​​the Rhine, there were severe weather events with strong thunderstorms and large hailstorms. On June 22, a debris flow in the center of the municipality of Cressier in the canton of Neuchâtel caused major damage. As a result, there was already a risk of flooding in some bodies of water at the beginning of July. The accumulated precipitation from the month of May to July destroyed agricultural crops in several regions.

affected areas

Belgium

In Belgium , the Walloon part of the country was affected. On July 15, the state infrastructure operator Infrabel announced the suspension of rail traffic in the entire region. There was a risk of flooding in the entire province of Liège and in parts of the provinces of Luxembourg , Namur and Walloon Brabant . Interior Minister Annelies Verlinden had the EU civil protection procedure activated. The neighboring country France announced the sending of helpers to the province of Liège. In the area of ​​the German-speaking Community , the Our overflowed its banks and flooded the village of Ouren , which is part of Burg-Reuland . Two people, including one in Aywaille , perished in the province of Liège . In the Eupen district of Nispert, a man with a swimming hoop jumped into the raging city stream, has been missing since then and rescue workers later found his body. In total, there were at least 14 deaths (as of July 16, 2021, 11:45 a.m.).

In mid-July, after heavy rains triggered by the Bernd low , there were heavy floods in various regions of Germany . North Rhine-Westphalia and Rhineland-Palatinate were particularly hard hit .

Due to the severe storms, at least 103 people were killed in both federal states. Among other things, two firefighters died in action in NRW. According to the first inventory, the number of victims is thus far higher than in the so-called century flood in 2002 , when 21 people were killed in Germany. Six houses collapsed in the Eifel . 200,000 people in North Rhine-Westphalia (NRW) and Rhineland-Palatinate (RLP) are affected by power failure. Defense Minister Annegret Kramp-Karrenbauer triggered the military disaster alarm for the two federal states on July 16, 2021 in order to increase the Bundeswehr's ability to act in terms of disaster relief .

Because the flood reached several substations, the power supply companies had to switch off the electricity in the affected areas. Cell phone networks and drinking water supplies had also collapsed in some of the affected areas.

Rhineland-Palatinate

The district of Ahrweiler is particularly hard hit , where the flooding of the Ahr left a trail of destruction and destroyed bridges and other infrastructure facilities. In the community of Schuld and the city of Sinzig alone , at least 28 people died. Twelve people who died in Sinzig were residents of a facility for the disabled. The floods came faster than the people could have been brought to safety.

The disaster was declared in the Vulkaneifel district .

Bavaria

A disaster was declared in several cities and districts in Northern Bavaria on July 10, 2021 . There was a power failure in Wilhermsdorf after a transformer house was flooded. The railway line from Neustadt an der Aisch to Bad Windsheim had to be closed due to flooding of the tracks. Numerous streets were under water. In Altmannshausen ( Markt Bibart ) a listed bridge was torn away in parts and was therefore impassable.

North Rhine-Westphalia

By July 16, 25 cities and districts in North Rhine-Westphalia were particularly affected by the flood. By the same day, according to the Interior Minister of North Rhine-Westphalia, Herbert Reul, 19,000 relief organizations had dealt with 30,000 missions in connection with the flood and the police had carried out a further 3200 missions.

The drastic consequences of the severe weather disaster in West Germany also made themselves felt in Euskirchen and Erftstadt . Due to the floods and the risk of collapsing the Steinbachtalsperre , several thousand residents in several villages had to leave their homes. The on shore entered Erftstadt flooding large parts of the Erftstadt urban area, several villages have been partially or completely evacuated and highways such as the A1 and A61 as well as the federal highway 265 had to be suspended due to the flooding and road damage. In the Erftstadt district of Blessem , the water flowed from the Erft through a residential and commercial area and paved a new way into the pit of the Blessem gravel works; several houses near Blessem Castle were washed down and damaged.

Because the Inde overflowed its banks, the Inden opencast mine was partially flooded and one person was subsequently reported missing.

On July 14th, the Eicherscheid flood retention basin in the Eifel and other retention basins near Horschheim, Weilerswist and Kerpen-Mödrath were opened to reduce runoff in the Erft.

Saxony

In Steinbach (Jöhstadt) in the Erzgebirgskreis a man was washed away by a flash flood on July 13, 2021, in Freiberg there was subsidence and a landslide.

Italy

The storms also reached eastern northern Italy and caused damage to agricultural crops. In Trentino-Alto Adige , a fallen tree damaged a cable car and several roads were broken, and a person was killed in Veneto .

Luxembourg

In the Grand Duchy of Luxembourg , too , heavy rain on July 14th and 15th caused numerous rivers to overflow their banks and flood neighboring towns. This affected Mamer , Vianden and Bettemburg , among others . Parts of the city of Echternach had to be evacuated on July 15, as did residents of several other places ( Vianden , Rosport , Steinheim , Born , Bour ). At Bollendorf the level of the Sauer reached 608 centimeters, the second highest value since records began. According to MeteoLux , an average of 60 to 80 liters per square meter had fallen in the country in the previous 24 hours. Serious damage was caused in the lower town of the state capital by the Alzette . The kerosene supply to the airport was interrupted due to the damage to a pipeline near Echternacherbrück .

Netherlands

Flood of the Göhl in the center of Valkenburg aan de Geul , Netherlands

The southern part of the Dutch province of Limburg was particularly hard hit . In the Heuvelland , creeks and small rivers burst their banks and caused serious damage. Because of the water masses, parts of the A2 , A79 and A76 motorways had to be closed. On July 15, parts of the city of Roermond , the provincial capital Maastricht , the Maas communities Stein and Eijsden-Margraten and the small town of Valkenburg were evacuated.

Switzerland

Flood in Bern on July 16
Rising Aare in Bern on July 13th

After heavy rains for days in the Alps , the Jura and the Swiss Plateau , numerous streams, rivers and lakes have burst their banks in several cantons since July 11, 2021, and landslides and debris flows have occurred in some places. Various towns were flooded and some traffic connections were interrupted. On July 14, the authorities declared the highest danger level for several bodies of water, especially the large lakes at the edge of the Alps .

Strong gusts of wind caused major property damage from July 12th to 13th, including in the city of Zurich , as well as disruptions in the transport network.

To flooding and local flooding occurred particularly in the river systems, the Aare , the Reuss , the Limmat and the Rhone and in the canton of Ticino . The Reuss burst its banks on July 13 in the cantons of Uri and Aargau . In Brugg and Gebenstorf where the Reuss and the Limmat flow into the Aare chess country and the Stroppelinsel were under water. In some communities, roads and bridges have been closed. As a precautionary measure, the canton of Uri closed the A 2 motorway next to the Reuss near Altdorf to traffic.

Debris flows hit the Upper Valais village of Oberwald and buried traffic routes and part of the settlement. The route of the Matterhorn-Gotthard-Bahn and the pass roads over the Grimsel , Furka and Nufenen Pass were closed. The traffic connections to Engelberg and the cantonal road Lausanne - Vevey were interrupted due to debris flows and landslides. Due to a rockfall, the main road Bellinzona - Airolo was closed since July 14th.

In Lucerne , Thun and other towns along the Reuss, the Aare and the Rhine, the municipalities had the fire brigade and civil defense set up mobile flood protection elements and flood barriers. Damage was also caused by the rising groundwater.

The flood caused by the tributaries in the Rhine below the mouth of the Aare meant that on July 13th, shipping on the Rhine at Basel had to be suspended. Shipping also stopped on Lake Lucerne , Lake Thun and Lake Biel .

The Birs flooded areas near the river near Basel. The Lake Biel rose due to the influx of the Aare River, the Zihl and Suze and due to the Jura water regulation in Regulierwehr port on the damage threshold and joined Nidau and Biel on the shore. On July 16, 2021, the Aare flooded in Bern .

Political reactions

Germany

The Prime Minister of North Rhine-Westphalia Armin Laschet , Vice Chancellor Olaf Scholz and the Prime Minister of Rhineland-Palatinate Malu Dreyer made their way to the disaster areas to get an idea of the situation. Chancellor Angela Merkel thanked the many helpers for their commitment and declared in a tweet from government spokesman Steffen Seibert on July 15 that her sympathy goes to the relatives of the dead and missing. Bavaria's Prime Minister Markus Söder also promised help for the affected countries.

The Deputy Prime Minister of Rhineland-Palatinate, Anne Spiegel (Greens), traveled to the flood events in Trier and Kordel . The example of Trier-Ehrang has shown, according to Spiegel, that the flood protection measures of the state and those of the municipalities are insufficient.

EU

EU Commission President Ursula von der Leyen promised aid to the affected EU countries, namely Belgium, Germany, Luxembourg and the Netherlands.

France, Italy and Austria offered rescue teams to help Belgium.

Switzerland

Federal President Guy Parmelin visited Biel and Lucerne and got an idea of ​​the situation, Federal Councilor Simonetta Sommaruga got an idea of ​​the Aare in Bern, for example in the Matte district . Parmelin regrets the catastrophe in Germany.

United States

US President Joe Biden has expressed his "sincere condolences" to Germany for the devastating floods in North Rhine-Westphalia and Rhineland-Palatinate. "It is a tragedy," said Biden on July 15 in Washington during a visit by Chancellor Angela Merkel. "Our hearts go out to the families who have lost loved ones." Merkel thanked them for their sympathy: "We really appreciate that." "The suffering of those affected affects me very much," said the Chancellor.
