Etiages et étirements : vers quelle modélisations ? : l'approche conceptuelle et l'analyse statistique en réponse à la diversité spatiale des écoulements en étiage des cours d'eau de l'Est français

Abstract : Hydrological drought of the last years, especialty the summer 2003, has clealy shown the vulnerability of human activitie exposed to water scarcity. Public authorities who use to monitor hydrological extermes should provide water resource .assessment and forecasting tools. The work relates to low analysis of rivers located in Rhine and Meuse basins. The contrasted physiographic characteristics are observed in order to be compared. The purpose in to propose a single mode fficient for all basins. Methods and modelling are based on recession analysis because during drought period the discharged of rivers essentially comes from groundwater flow. Finally uncertainties related to conceptual aspects have reduced by statistical and probability approaches
