Notre connaissance des étiages historiques était jusqu'ici en grande partie limitée par les observations hydrométriques disponibles, qui deviennent rares et disséminées avant les années 1960. Les récents travaux sur une réanalyse hydroclimatique de long terme sur plus de 600 bassins versants faiblement anthropisés en France permettent à présent de ...

Les sécheresses récurrentes que connaît la France depuis l'été 2003 et notamment celle du printemps 2011, de l'été 2015 ou encore de ce printemps, ont rappelé la sensibilité de nos systèmes aux extrêmes hydrologiques et à la disponibilité de la ressource en eau, et des enjeux de l'adaptation dans la perspective du changement climatique. Les sèchere...
Over the past two decades studies on climate history have contributed to improving knowledge on past droughts, particularly through the study of pro pluvia rogation ceremonies (e.g. Martin-Vide and Barriendos 1995, Piervitali and Colacino, 2001, Garnier, 2010). Simultaneously, other authors have proposed studying social responses to past climatic e...
This research presents a study of extreme low flow events that occurred from 1871 onwards in a large number of near-natural catchments in France. It aims at assessing and comparing their characteristics to improve our knowledge on historical events and to provide a selection of benchmark events for climate change adaptation purposes. The historical...
