Abstract: The rising frequency of floods, coupled with increasing human encroachment on water corridors and floodplains, makes floods severe disasters. In 2007, the European Union enacted the Floods Directive, guiding member countries in legislation for identifying flood hazard and risk areas. Despite significant human impacts, current flood hazard mapping often neglects scenarios from extreme events. Stochastic land use changes, driven by economic and social interests, should be considered. Mitigation measures, like dams and levees, aimed at reducing flood risk can alter flow regimes and transfer risk. Levee construction changes floodplain retention capacity, influencing flood peak attenuation and propagation time. This article introduces the analysis of exceptional events in assessing flood hazards and risks through examples of man-made extreme flood events using detailed hydraulic models.
