The extreme flood event of July 2021 which affected Germany, Belgium, and the Netherlands was a rapid onset event which led to severe damages, loss of life, and disruption to infrastructure (Dietz et al. 2021). Several characteristics of this event posed challenges for warnings and risk communication. While there have been significant improvements in recent years in warning systems for clear water floods in large rivers in Germany (Kreibich et al. 2017; Thieken, Annegret H., et al. 2016), rapid onset events with debris and high sediment transport rates pose unique challenges. This project seeks to understand where the existing challenges are for flood early warning systems for rapid onset events. This will be studied at a regional level and for different groups including private households and infrastructure owners. In addition to time scale issues, cascading processes present a challenge for early warning systems. The role of cascading processes will be investigated in the context of impact-based warning approaches. The project consists of three steps:
