| Zusammenfassung |
| Understanding network infrastructures and their operation under exceptional
circumstances is fundamental for dealing with flood risks and improving the
resilience of a territory. This work presents a method for evaluating
potential network infrastructure dysfunctions and damage in cases of
flooding. In contrast to existing approaches, this method analyses network
infrastructures on an elementary scale, by considering networks as a group
of elements with specific functions and individual vulnerabilities. Our
analysis places assets at the centre of the evaluation process, resulting in
the construction of damage-dysfunction matrices based on expert interviews.
These matrices permit summarising the different vulnerabilities of network
infrastructures, describing how the different components are linked to each
other and how they can disrupt the operation of the network. They also
identify the actions and resources needed to restore the system to
operational status following damage and dysfunctions, an essential point when
dealing with the question of resilience. The method promotes multi-network
analyses and is illustrated by a French case study. Sixty network experts
were interviewed during the analysis of the following networks: drinking
water supply, waste water, public lighting, gas distribution and electricity
supply. |
