Resume Les espaces urbanises soumis a des risques moderes d'inondation pour les vies humaines sont souvent peu consideres dans les etudes sur la vulnerabilite aux risques naturels en depit des enjeux qu'ils representent en termes de gestion de crise. Comment les riverains y font-ils face au danger et quelles sont leurs << bonnes raisons >> d'agir? A partir de l'etude socio-geographique de deux inondations recentes (2000 et 2003) dans la peripherie toulousaine (Sud-Ouest de la France), nous montrons que les caracteristiques de l'alea dans les vallees etudiees influencent les representations du risque et par consequent les motivations a se proteger. Face au risque majeur, la vulnerabilite sociale se trouve ainsi augmentee. Pour ameliorer la resilience des populations, il convient d'adapter la communication sur les risques: personnaliser l'information, ameliorer la comprehension de l'evenement vecu et mobiliser de nouvelles formes de mediation entre gestionnaires et riverains.

Abstract Urbanized areas subjected to moderate risks to human lives from flooding are often underestimated in studies on hydrological vulnerability, despite the roles they play in terms of crisis management. How do riverine residents face flood risk and what do they consider good reasons to take action? Based on a socio-geographical analysis of two recent floods (in 2000 and 2003) near Toulouse (southwest France), we show that the characteristics of the hazard in the studied watersheds influence the hydrological risk perception and thereby people's motivation to take action. Confronted by a major risk, society's vulnerability is clearly increasing. In order to improve the resilience of the population, we show that it is necessary to adapt the communication on risk: by personalizing information, improving the hydrological explanation of the flooding process, and initiating new forms of mediation between water management or administration and the riverine inhabitants.
