| Zusammenfassung |
| In 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. |
