  • 摘要:Several severe flood events hit Germany in recent years,with events in 2013 and 2016 being the most destructive ones, althoughdynamics and flood processes were very different. While the 2013 event was aslowly rising widespread fluvial flood accompanied by some severe dikebreaches, the events in 2016 were fast-onset pluvial floods, which resulted in surface water flooding in some places due to limited capacities of the drainage systems and in destructive flash floods with high sediment loads and clogging in others, particularly in small steep catchments. Hence,different pathways, i.e. different routes that the water takes to reach (andpotentially damage) receptors, in our case private households, can beidentified in both events. They can thus be regarded as spatially compoundflood events or compound inland floods. This paper analyses how differentlyaffected residents coped with these different flood types (fluvial andpluvial) and their impacts while accounting for the different pathways(river flood, dike breach, surface water flooding and flash flood) withinthe compound events. The analyses are based on two data sets with 1652 (forthe 2013 flood) and 601 (for the 2016 flood) affected residents who weresurveyed around 9 months after each flood, revealing littlesocio-economic differences – except for income – between the two samples. Thefour pathways showed significant differences with regard to their hydraulicand financial impacts, recovery, warning processes, and coping andadaptive behaviour. There are just small differences with regard toperceived self-efficacy and responsibility, offering entry points fortailored risk communication and support to improve property-leveladaptation.
