Stream water chemistry at catchment outlets is commonly used to infer the flowpaths of water through the catchment and to quantify the relative contributions of various flowpaths and/or end-members during, e.g., storm events. For this purpose, the nu

Climate change and water quality responses in agricultural catchments with high legacy storages of nutrients
Autor: Ophelie Fovet, Laurent Strohmenger, Remi Dupas, Patrick Durand, Mikael Faucheux, Yannick Hamon, Laurent Jeanneau, Patrice Petitjean, Laurent Ruiz, Chantal Gascuel-Odoux
The effects of climate change on the quality of freshwaters remains poorly investigated while these effects are likely to be ambiguous. Indeed, such effects are partly direct such as temperature control on reaction rates, and partly indirect such as
