catchment scale. A SWAT model approach to assess the evolution of the many hydrological
components of the Garonne catchment (Southern France) is deployed in this study.
Performance over the calibration period (2000–2010) are satisfactory, with Nash–Sutcliffe
ranging from 0.55 to 0.94 or R2 from 0.86 to 0.98. Similar performance values are obtained
in validation (1962–2000). Water cycle is first analyzed based on past observed climatic …
