Flood Risk Mitigation in a Mediterranean Urban Area: The Case Study of Rossano Scalo (CS – Calabria, Italy)

Abstract

Urban flooding is recently affecting several towns in the Italian Mediterranean region. The study focuses on the interconnection between the sewer network of the town (Rossano Scalo) and the main water course (the Citrea Creek) flowing through it. An integrated approach considering both town planning and hydraulic aspects lead the search for potential flood risk mitigation solutions. Through the use of GIS and field surveys a highly urbanized sub-basin was selected and analysed. The hydrologic- hydraulic system was simulated through SWMM software, paying attention to interactions between the minor and the major system. Critical nodes (urban flooding points) were finally considered for planning potential mitigation solutions.
