Stakeholders' issues for action during the warning process and the interpretation of forecasts' uncertainties

L. Créton-Cazanave and C. Lutoff

Abstract. This article considers the socio-geographical approach carried out as part of the MedUp program. It presents a study of the ways that the French "actors" manage forecast uncertainties during a flash flood warning process. In order to better understand the role of forecasts' uncertainties in decision making, we focused on the actions people took and how what they say explains their actions. The practices of actors involved in warnings for the Vidourle watershed (Gard, France), in particular, are analyzed using a practice-based approach. A set of categories of the "actors" was developed based on their descriptions of the problems they faced during the flash flood warning, independent of their socio-professional status and position in the warning chain. Five actor profiles result from this: Translators, Managers, Committed, Navigators and Vulnerable. For each profile, specific action contexts are defined, determining how each deals with uncertainty.
