Apport de la réalité virtuelle pour l’appropriation de l’aléa submersion marine

Abstract

In the coastal towns of Normandy affected by marine flooding, new challenges are imposed on the stakeholders. Indeed, the latter must coordinate these environmental constraints, the complexity of development or protection procedures, while maintaining the attractiveness of the territories. In this context, the social acceptance of risk management projects becomes a fundamental issue that depends on the appropriation of knowledge. Acceptability requires a co-constructed reflection between scientists, decision-makers and populations, the starting point of which is the sharing of a common scientific culture. This is why, beyond the improvement of knowledge, the originality of the REVE Cot project lies in the dissemination of results through virtual reality. The aim is to allow stakeholders to experience historical hazards and those estimated for the year 2100 in a so-called immersive room. In order to determine the contribution of this new technology, a questionnaire was filled in by the stakeholders (50) before and after having lived this experience. A large majority (78 % for the elected representatives) reported feeling more concerned and better able to estimate the extent of sea level rise in their area after having lived through this experience. 98 % of people said that this tool is a good communication tool for the appropriation of knowledge.
