Flood overflow in Wiesbaden: Construction is delayed due to frost and weather!

On March 25, 2025, the flood overflow in the spa park pond in Wiesbaden should already be completed. But the construction work delays themselves due to unfavorable weather conditions and technical challenges. This reports Wiesbaden Aktuell . Despite the setbacks, important elements of the overflow are already installed, including the overflow threshold and the relief channel.

The project aims to offer protection against heavy rain and floods. The flood overflow should derive excess water during heavy rain. However, problems with the Rambach recovery and unexpectedly high water drainage have made problems connecting to the construction progress. In addition, Frost delayed the planned dismantling of natural stones for the overflow threshold.

refilling and green areas

The refilling of the Kurparkweiher has already started, but could still take a few weeks. Natural influx from the Rambach feeds the pond with water. The restoration of the green areas around the pond is planned for April. Mayor Christiane Hinninger said optimistically about the completion of the project.

These modernized measures are necessary because climate change in Germany increasingly brings flood risks. An international research group led by Professor Ralf Ludwig from the LMU in Munich has shown that intensity and frequency of heavy rain events have increased in recent years. In a report by lmu , extreme slides do not always lead to exuberances.

climate change and its effects

The consequences of climate change are not only felt in Bavaria, but also affect the entire federal territory. The federal government's monitoring report shows that the middle air temperature in Germany has risen by 1.5 degrees since 1881 - an increase of 0.5 degrees above the global average. The report emphasizes that the summer heat increases while wintry rainfall has increased by 25 percent. This has direct effects on infrastructure, agriculture and human health.

The weather extreme, including storms and heavy rain, have led to considerable damage in recent years, as the report of Science.de 2018 was a particularly extreme year with insurance damage of around 3.1 billion euros due to weather extremes. The increase in temperatures and the changed precipitation patterns make projects such as the flood overflow in Wiesbaden necessary to meet the challenges of climate change.
