Nowadays, flood risk management is gaining importance in order to mitigate and prevent flood disasters, and consequently the analysis of flood risk components is becoming a key research topic. In this paper, we propose a methodology for large‐scale analysis of flood susceptibility and vulnerability. The methodology is based on a mathematical index, which considers local topography and basic information about the flood scenario to reproduce flooding processes. Its application allows for considering different levels of complexity of flood scenarios, from localized flood defence failures to complex hazard scenarios involving river reaches. The methodology synthesizes the spatial distribution of the index values into maps and curves that can be used to rank the susceptibility and implement a vulnerability analysis in the area of interest. The components of the methodology are tested in two flood plain areas in Northern Italy recently affected by floods. The results show that the methodology can provide an original and valuable insight of flood susceptibility and vulnerability processes.
