Abstract

Flood risks in urban areas constitute today an important research topic in geography, because of increasingly disastrous consequences of certain pluviometry events in more and more important cities. The urban area of Sfax in southern Tunisia, with 22000 hectares and 600,000 inhabitants was also affected, during the five last decades, by floods with recurrent catastrophic consequences. If the flood hazards at the base of these floods risks are relatively well known, the vulnerabilities of the involved stakes are much less. This paper aims to high light, using spatial analysis and GIS mapping, the effective links between territorial features of Sfax and flood processing conditions and proposes a new approach to the risks through a better characterization of its vulnerabilities, which seem largely related to economic factors, human and functioning spatial structures and shapes. The results have confirmed that the existing protection infrastructures of the of Sfax urban area are no longer adequate to deal with the new vulnerabilities, and that it is high time for the risk management of flood to be directed to wards the attenuation of these vulnerabilities by seeking solutions in a future installation by the adoption of a PPRF, one (CMP) and by the integration of risk of flood in the urban development.
