چکیده انگلیسی
A GIS-based procedure for mapping pluvial flood risk in urban areas is proposed; risk is expressed through an index calculated as the sum of susceptibility and potential impact, combined in a matrix. The susceptibility is defined as the probability of a flooding to occur, because of the ground morphology and the spatial probability density of historical floodings. The potential impact was evaluated by considering the consequences of damages on human health, environment, cultural heritages and economic activities, and accounts for the potential cost of damage. Both the susceptibility and the potential impact are calculated by elaborations of base-data in GIS environment. Despite many limitations, the methodology furnishes a tool for a preliminary screening of areas potentially subjected to pluvial flood, useful for a municipal scale mapping. It permits comparative analysis for detecting areas higher at risk, helping prioritizing the emergency management and the planning of mitigation actions.
