Apport de la sûreté de fonctionnement à l'analyse spatialisée du risque inondation

Abstract : The urban technical systems are subjected to major stakes, such as climatic and territorial issues, which affect their functioning. These stakes can make the technical systems vulnerable to natural hazards. But, the traditional methodologies used for vulnerability analyses are hazard-oriented. They are focused on the hazard as a physical process and on the direct damages to the system. This approach is found to be unsuitable for analyzing systems with a high level of complexity, interconnectedness and linkages with other urban technical systems, and with many and varied failures processes. This paper analyzes the vulnerability of guided transport systems facing flood risk. This research focuses on an innovative approach of risks analysis that associates safety and dependability methods with methods from geomatics. The geographical information allows this combination between these two very different types of methods. The chosen approach is system-oriented in order to elaborate a methodology for characterizing any direct and indirect damages to the system. The global goal is to highlight the contribution of this innovative approach for the urban risk management, and so improve the resilience of cities facing of flood risks.
