ABSTRACT
ABSTRACT VIE index is a tool to assess vulnerability of residential houses for people in case of flood. It aims to evaluate a potential number of deaths in “dangerous houses” due to configuration and location of buildings. It allows to conduct cost-efficiency analysis of adaptation strategies to protect human lives.
Successfully applied to seven municipalities impacted by Storm Xynthia (2010, in France), some limitations were identified as the index was only designed for centennial floods or the cost-efficiency was conducted comparing strategies one after the other.
This paper shows that (i) prevention warning and evacuation appears to be the only strategy for which efficiency increases with the flood intensity and that (ii) mixing adaptation strategies allows to enhance efficiency and decrease costs.
