Preparation for the XII^th IAHS Scientific Assembly, 5-10 October 2025 is at full speed. This event will be an experiment in community building by having all presentations in Plenum to encourage more joint scientific discussions within the hydrological society. We will allow more time for in-depth conceptual understanding as well as plenty of flash presentations of ongoing work and new results.

Suggest pre-events now!

Instead of parallel meetings, we open for pre-event meetings as side events. Therefore interested leaders of International Commissions, Working Groups and Committee Leaders should reach out to the IAHS Secretariat or Secretary General as soon as possible so that facilities can be provided and participants can arrange their stay accordingly. Side event details will be posted on the website as soon as they’re confirmed, so stay tuned!

Join us in India next year for what promises to be an engaging and transformative event for the hydrological sciences!
