IAHS Fellow Award
The IAHS is pleased to announce the introduction of a new distinction: the IAHS Fellow Award. This prestigious recognition has been established to honour outstanding contributions to the hydrological sciences community and to celebrate excellence across the global IAHS network. The IAHS Fellow Award will be presented every two years, recognising five distinguished scientists—one from each continent (North America, South America, Africa, Asia-Oceania, and Europe). This structure reflects IAHS’s commitment to global representation and inclusivity within the hydrological sciences.
