Hochwasser – ein unterschätztes Risiko

Flood events – an underestimated danger Floods events are a constant threat to life, health and property of the population as well as for industry, agriculture and infrastructure in flood‐prone areas. But of concern are not only the direct effects: historical contamination – ticking ”time bombs" – in the sediment can re‐enter the water column through erosion. Once present, they can have negative impact on water quality and endanger health of aquatic organisms and humans. This article features several studies on the hazardous potential of flood events and especially the findings of a combined hydrological and ecotoxicological investigation strategy.
