Abstract
The OSIRIS-Inondation tool was created as part of the OSIRIS FP5-IST project
and is now used by many French towns to generate a flood action plan for crisis
preparation and delivery of operational support to the emergency services during
crisis management or training phases. At present, the action plan is calculated on
the basis of accurate information on available human and material resources,
crisis scenarios, key facilities and the actions needed to protect the latter, while
taking account of the direct, local impact of the flooding. However, the ability to
correctly implement an action plan has never been analysed – notably in the
event when a flooding closes down transport networks and thus prevents access
(in full or in part) to the key facilities in question. The goal of the ACCEL
project (funded by the Picardie Region in northern France) is to develop a
method for calculating the accessibility of predetermined facilities and to
integrate it into the OSIRIS platform. In order to address these issues, we
developed an approach for (i) identifying the data required to calculate
accessibility, (ii) cross-checking these data against flood scenarios,
(iii) determining which sections of transport networks will be disrupted and
(iv) calculating optimal itineraries to key facilities. Validation of this
methodology in a case study of the Compiègne urban area (using ArcGIS
software) enabled the development of a self-contained route-planning module for
integration into OSIRIS action plans.
