A recent flash flood event in the Mandra region west of Athens, Greece, turned urban roads into fast-flowing rivers, and caused many fatalities and economic damages. After this incident a great dispute arose whether the devastating results were due to the extreme nature of the storm event or to the poor flood protection works. In this study, we present a preliminary analysis of the urban flood inundation at the wider area by taking into account the uncertainty introduced by the input discharge, topography and hydraulic characteristics. Finally, we discuss how hydraulic works could reduce the severity of the event.
