This document outlines an integrated methodology for the assessment of current and future flood risk at the European scale. Changes in flood hazard obtained by combining highresolution regional climate scenarios with a hydrological model are transformed into direct monetary damage assessments using water depth-damage functions and land-use information. Results of the methodology are presented for the Upper Danube and Meuse catchments. For the Upper Danube the estimated total damage of a 100-year flood is projected to rise by ~40% of the current damage estimate (corresponds to an increase of €18.5 billion) for the high emission scenario (A2) and ~19% for the low emission scenario (B2). The number of people affected in the Upper Danube is projected to increase by 242,000 (~11%) for the A2, and 135,000 (~6%) for the B2 scenario. For the Meuse catchment, the total damage of a 100-year flood is projected to increase by ~14% for the A2 scenario and ~11% for the B2 scenario. For both scenarios, the estimated increase in number of people affected is approximately 4%.
These results serve as an initial, interim assessment until better information becomes available and some parts of the methods are elaborated in more detail. Several assumptions underlie the calculating of these costs, and should be kept in mind when interpreting the results.
