|Abstract:||River floods generate a large share of the socio-economic impact of weather-driven hazards worldwide. Accurate assessment of their impact is key priority for governments, international organizations, re-insurance companies and emergency responders. Yet, available databases of flood losses over large domains are often affected by gaps and inconsistencies on reported figures. In this work, a framework to reconstruct the economic damage and population affected by river floods at continental scale is applied. Pan-European river flow simulations are coupled with a high resolution impact assessment framework based on 2D inundation modelling. Two complementary methods are compared in their ability to estimate the climatological average flood impact and the impact of each flood event in Europe between 1990 and 2013. The event based method reveals key features, such as the ability to include changes in time of all three components of risk, namely hazard, exposure and vulnerability. Furthermore, it skilfully reproduces the socio-economic impact of major flood events in the past two decades, including the severe flooding hitting the Central Europe in June 2013. On the other hand, the integral method is capable of reproducing the average flood losses occurred in Europe between 1998 and 2009. Strengths and limitations of the proposed model are discussed, to stress the large potential in filling the gaps of current datasets of flood impact.|
