The role of residual risk on flood damage assessment: A continuous hydrologic-hydraulic modelling approach for the historical city of Rome, Italy

Ordinary and residual flood risk assessment is a crucial topic in hydrology with a variety of practical implications for improving the extreme event management. Nowadays and in such context, the continuous hydrological-hydraulic modelling is an emerging approach and this study supports the conclusion that it can provide a very informative flood risk assessment. Moreover, when the study domain includes relevant and very expensive historical centers, like Rome, such methodology allows for a complete characterization of the risk providing the necessary information for decision-makers.
