Flooding is a pervasive natural hazard across Europe, stemming not only from persistent precipitation—locally or upstream of rivers—but also from sea and groundwater sources. The flood risk at any given location encapsulates both the probability of a flood event and the potential for property and economic damage. This report presents a comprehensive framework for calculating potential home insurance losses from European flood events based on open data sources, varying by return period and climate change scenarios.
