The 7th International Symposium on River Science, held October 6–9, 2025 at UC Davis, will feature keynotes, special sessions, posters, and field trips centered on three themes: reconnecting rivers as integrated biophysical systems, restoring them for biodiversity, and revitalizing human–river relationships. Bringing together global experts from science, policy, and practice, the program will highlight cutting-edge research, collaborative solutions, and on-the-ground restoration efforts.
