Here we highlight the career contributions of Chantal Gascuel-Odoux in hydrology, soil science and agronomy. These contributions are divided into four main categories: i) Influence of soil and subsoil properties on hydrological processes; ii) Water, solute and particulate transfer at the catchment scale; iii) Design of integrated approaches to landscapes and territorial management; iv) Contributions to public policies and public debates. We conclude by emphasising Chantal’s human qualities, which we particularly appreciate as former mentees.
