Adaptation of Residential Buildings to Coastal Floods: Strategies, Costs and Efficiency

Résumé

As the first defence to the natural environment, residential buildings are responsible for protecting human lives and assets in society. Nevertheless, some residential buildings in coastal areas are located in places where the population is exposed to the risk of drowning. Rise in the sea level due to climate change could increase these risks. Therefore, this chapter presents and discusses a framework for estimating the cost-effectiveness of adaptation strategies for buildings subjected to coastal floods. The chapter first describes the Vulnérabilité Intrinsèque Extrême (VIE) or Extreme Inherent Vulnerability index, which is a useful tool to identify the buildings where people could be trapped and drowned during floods. Afterwards, four adaptation strategies are presented and discussed focusing on their costs and effects on the VIE index. Finally, two case studies illustrate how the framework could help the decision-makers to compare or combine the adaptation strategies in a cost-effective way.
