Abstract

The aim of this paper is to show that the positive trend to sea levels rise is not a linear phenomenon and that across the twenty-first century the role of cyclones - whose simulation for the future is very difficult to establish with numerical climate models - will be the main cause of coastal flooding. The societal implications of sea levels rise on floodplains are also of human responsibility that landscape areas are vulnerable by not incorporating enough this hypothesis, often out of ignorance but also for economic reasons.
