“…This research focuses on urban resilience to natural hazards. We use here the resilience concept in a previous work: "The ability of a city to absorb a disturbance and recover its functions after the disturbance" (Lhomme et al, 2011). This definition implies that the urban system is able to reduce globally the effects of a perturbation and that its functions (decisionmaking, economic development, cultural development, life support, etc.)…”

Abstract. Natural hazards threaten the urban system and its components that are likely to fail. With their high degree of interdependency, urban networks and services are critical issues for the resilience of a city. And yet, network managers are scarcely aware of their flaws and dependencies and they are reluctant to take them into account. In order to develop an operational tool to improve urban resilience, we propose here an auto-diagnosis method to be completed by network managers. The subsequent confrontation of all diagnoses is the basis of collaborative research for problem identification and solution design. The tool is experimented with the Parisian urban transport society.

“…Thus, absorption capacity analysis is focused on networks' redundancy assessment. Resistance capacity analyzes dysfunctions induced by damaged components and takes into account interdependencies between networks (Lhomme et al, 2011). Recovery capacity analysis considers accessibility between restoration center and damaged components.…”

“…For instance, some articles outline numerous resilience definitions (Mayunga, 2007) and it appears that there are many redundancies (Table 1). So, thanks to the study of many definitions in different disciplines, we have defined urban resilience, in our context of research, as "the ability of a city to absorb disturbance and recover its functions after a disturbance" (Lhomme et al, 2011). In other words, urban resilience can be defined as the ability of a city to operate in a degraded mode (absorption capacity) and to recover its functions, despite the fact that some urban components are disrupted (recovery capacity; Lhomme et al, 2011).…”

International audienceIn Europe, river floods have been increasing in frequency and severity. These circumstances require the management of flood risk by integrating new concepts like urban resilience. Nevertheless, urban resilience seems to have no accurate meanings. That is why researchers are primarily concerned with defining resilience. Nevertheless, focus on research object seems to be more important than focus on conceptual debate (Resilience of what? Rather than what is resilience?). Thus the methodology designed here is focused on urban considerations. In fact, a system approach emphasizes technical networks’ importance concerning urban resilience. Principles and assumptions applied in this research finally lead to the analysis of how urban networks are able to face natural hazards. In this context, a Web-GIS has been developed for analyzing resistance capacity, absorption capacity and recovery capacity of different technical networks. A first application has been carried out on a French agglomeration in order to analyze road network absorption capacity. This application is very specific but, thanks to this example, it is already possible to highlight the methodology’s usefulness

Abstract. The vulnerability of critical infrastructures facing hazards is a burning issue for urban risks management. In this context, developing methodologies for analysing the causes and consequences of critical infrastructures vulnerability appears necessary for improving the proper functioning of cities that strongly depend on such infrastructures. The critical infrastructures are complex socio-technical systems in which the components are particularly interdependent. Interdependencies also exist between critical infrastructures. All these interactions may imply many failures caused by cascade effect in a context of risks. After a review of existing methodologies for assessing the interdependencies within and between critical infrastructures, the paper develops a global methodology based on dependability methods in order to automatically produce the scenarios of failures caused by cascade effect within a rail transport system, as an example of critical infrastructures, facing a flood hazard, as an example of urban risks. The paper discusses the generalizability of the methodology to other critical infrastructures.
