ABSTRACT

ABSTRACT: Hydrological droughts are a major concern for decision makers throughout Europe. This paper presents the main lessons learnt from developments carried out at Irstea (France) to build hydrological tools and fulfil the needs of decision makers for improved low-flow forecasting and management. We address the issues of selection and comparative assessment of hydrological models, predictive uncertainties and application to reservoir management. The main challenges in developing improved tools for operational services are discussed.
