Conduite à contre-courant. Les pratiques de mobilité dans le Gard : facteur de vulnérabilité aux crues rapides

Abstract : Flash floods trigger the highest mortality rate in natural disasters because of the rapidity of their onset and extreme violence. They arrive suddenly and surprise people who are in the midst of their daily activities, particularly striking during people's travels. For each catastrophy, up to half of the deaths are road users. Hydro-meteorological research allows for more prediction lead-time and can reduce uncertainty. However, social vulnerability remains an outstanding focus. Experts call for a comprehensive integration of social and natural sciences to better understand public responses. In this context, this thesis addresses people's travel patterns during flash floods and makes two assumptions : i) people's unwillingness to change their daily routines, ii) discrepancy between individual space-time representations and actual flash flood phenomenon characteristics.

Using questionnaires or cognitive maps to interview a total of 1 428 residents and tourists visiting the Gard « département », we demonstrated that « at risk » travel patterns result in a mix of three factors : spatio-temporal exposure, cognitive understanding of risks on the road, but also daily family and professional constraints. Based on our analysis, we suggest a range of targeted preventative actions.
