The flooding in mid-July 2021 caused extensive damage along the Erft, Inde, Vichtbach, and Wupper rivers in North Rhine-Westphalia (NRW) and along the Ahr River in Rhineland-Palatinate (RLP). KAHR is supporting the (re)construction process and making a scientific contribution to flood risk management following the flood disaster to make affected regions more resilient. Building on the predecessor project KAHR (2021–2025), KAHR2.0 analyzes completed and ongoing measures, identifies best practices, and develops strategies for Europe-wide transfer.

Specifically, in KAHR 2.0 we...

• Develop climate-resilient protection objectives that are differentiated according to the sensitivities of land uses and infrastructure
• Derive implications for protection strategies and measures from scenarios involving heavy rainfall and flooding under climate change conditions
• Analyze the implementation and acceptance of natural and engineered water retention measures and identify further potential
• Analyze the impact of new legislation regarding climate-resilient reconstruction and flood prevention
• Analyze the impact of existing reconstruction funding
• Facilitate knowledge transfer and exchange of experience
• Consolidate project into a digital online tool
