Duh sees the need to catch up with floods and precautions in the field of preventing floods, especially when it comes to protection against floods in natural conditions, such as renovation of flows and rivers. Thanks to such measures, water can spread better and slowly flow again. “The rivers and streams, finally, need greater space, water must be restrained in intact forests, meadows and water-fingers,” said Muller-Cranner.
Statistically, the flood of the century occurs only once every 100 years, but: “During the climatic crisis, the water level of this amount can be expected more often in the future,” writes environmental assistance.
Duh calculated the risk of floods for federal states from the region, affected by damage, and the number of living addresses affected by the damage. The degree of risk is especially high if, in accordance with the definition of the EU, there is a large area of flood risk, and at the same time there are many addresses of housing in possible flood areas.
Bavaria has the greatest risk
In Bavaria, risk assessment is the highest. There, with more than 65,000 addresses, a particularly large number of people are at risk of flooding, at the same time in the case of a century of flood of 4.25 percent of the country with significant damage for people, the environment, cultural heritage and economic activity. For comparison: in the Northern Rhine Station, this will take place in 6.8 percent of the country, but with about 28,000 home addresses are much fewer people than in Bavaria, they will be at risk of flooding.
The share of risk areas in the state zone is also high in Brandenburg (6.2 percent), Saxony-Anhalt (5.9 percent), Baden-Württemberg (4.7 percent) and Hesse (4.6 percent). This is the lowest in Mecklenburg-Western Pomerania with 0.7 percent.
According to DUH, calculations are based on the data of the General Association of German Insurers and the Federal Institute of Water Research.
