Sensitivity of water quality of three contrasted north-eastern French watersheds to climate change (2006-2100) using SWAT model

International audience; The SWAT model has been chosen to assess climate change impacts on water quality of three subbassins ofnorth-eastern France: located on headwaters of three major rivers of France (Loire, Seine and Rhône riversrespectively). These watersheds have a size less than 3000km² and present different hydrogeological andgeological characteristics. Land-use as well as their agricultural practices being also diversified, the threewatersheds studied constitute a relevant experimentation area. The goal of this study is to assess local vulnerability of surface water quality (sediments, nutrients,dissolved oxygen loads) to climate change (2006-2100) following the Representative Conc…
