Heavy rain risk: New map shows endangered areas in Wedel!

In Schleswig-Holstein, a new information card was published for danger from heavy rain. This card, which the Federal Office of Cartography and Geodesy (BKG) presented in cooperation with Environment Minister Tobias Goldschmidt in Wedel, shows areas that are particularly susceptible to flooding in heavy rain. With this comprehensive card, not only the risk is made visible through heavy rain events, but also enables a targeted improvement in the precautionary measures.

climate change has increased the frequency and intensity of heavy rain events in recent years, which is why the creation of this map is of great importance. "The further climate change increases, the more we have to do with heavy rain events. With this card we can identify particularly endangered areas and improve heavy rain provision," said Environment Minister Goldschmidt.

Details on the map and their use

The card covers a wide area and represents how heavy rain events can also influence affected areas outside of flow water. The map shows essential parameters such as the maximum water depth, the flow direction and the maximum flow speed. In order to define the risk, two scenarios were taken into account:

• an extraordinary event with a return time of 100 years and a duration of one hour.
• an extreme event with a precipitation amount of 100 mm with an hour.

The notification card serves as an important instrument for risk assessment of heavy rain and offers a solid basis for further detailed analyzes. "The information card is an important tool to estimate the risk of heavy rain events," emphasized Goldschmidt.

In the city of Wedel, work is already being worked on with heavy rain events. The city relies on the concept of water -sensitive urban development, which aims to minimize the negative effects of heavy rain through targeted structural measures. A close cooperation between urban planning, city drainage and investors create measures that contribute to the long -term improvement of the infrastructure.

In this context, the so-called sponge city principle was introduced. This concept enables rainwater to be saved within the city in various places before it gets into the sewage systems. This reduces the risk of overloading the wastewater systems massively and evenly initiating rainwater into canal operation.

In addition to this important map, the country also publishes guidelines for heavy rain risk management. This guide gives decision-makers in the municipalities valuable information on the implementation of effective preventive and risk management strategies in the event of heavy rain. In order to raise awareness of water hazards, the Ministry of the Environment has been carrying out a campaign with the motto "Wasserstsh" for a year and a half. The population is thus informed about preventive measures in the context of heavy rain.

The new information card for the risk of heavy rain is accessible to the website of the State of Schleswig-Holstein and in the geoportal of the geodata infrastructure Germany. This initiative shows the proactive approach of Schleswig-Holstein, to take the effects of climate change seriously in planning and infrastructure development and to be prepared for future challenges.
