The Biohydrology7 meeting will be held in Gandia (Spain) in October 2023 (18th-22nd). The aim of the BioHydrology conferences is to provide a forum to share knowledge and networking about any topic related to the interactions between biotic systems and hydrology. Biohydrology aims to gather scientists and practitioners dealing with issues in the field of hydrology, biohydrology, biology, ecohydrology, ecology, geography and engineering in natural, agricultural, forestry and anthropogenic areas. The theme of the Biohydrology7 will be “Biota, water and humans. Management for a sustainable world”. We are planning two conference days (posters and talks), one day of mid-conference field visit and two days for a post-conference tour.
