The coastal zone of the Campi Flegrei volcanic district is prone to a wide spectrum of natural hazards, including earthquakes, tsunamis, flash floods, ground deformation, landslides and coastal erosion. In this research we focus on flash flood phenomena occurred in the Pozzuoli catchment, by analyzing historical documents (e.g. newspapers, archive reports, web site news) and integrating the results with daily rain time series of the rain gauge station of Pozzuoli city. In order to understand the evolution of these phenomena, we analyze the 6 November 2011 event that hit the city of Pozzuoli. The study includes the description of meteorological conditions, rainfall properties, ground effects obtained by a web-based research and results obtained simulating flood propagation by means of FLO-2D code. Preliminary results of our research provide a contribution for the understanding of flash floods and flow processes in the study area as well as relevant information for hazard and risk assessment.
