EGU25: Unmissable Sessions, Insights, and Networking Opportunities!

If you are planning to attend the EGU 2025 Annual General Assembly—whether in person or online—this blog is a must-read!

The HEPEX community of practice will gather at EGU25 (27 April – 2 May, Vienna) to share knowledge, exchange ideas, and discuss the latest scientific and operational advancements in hydrological forecasting.

To help you navigate the event, we have compiled key sessions you won’t want to miss. And if you are looking to connect with fellow HEPEXers and EC-HEPEXers, you can usually find them on the red level at the Vienna International Centre.

This year the sub-division on Hydrological Forecasting (HS4) will run 9 sessions focusing on topics like:

• Forecasting hydrological extremes: (flash) floods, droughts and water scarcity
• Improving and quantifying forecasting methodologies and uncertainties
• Operational and impact forecasting, preparedness and decision making
• Hybrid hydrological forecsating using physically-based and machine-learning models

Prior to highlighting the relevant sessions, we would like to draw your attention into:

• The social HEPEX/EC-HEPEX evening is scheduled for Thursday (1 May) at 20.45 at the Melker Stiftskeller (Schottengasse 3, 1010 Wien, Austria) restaurant. If you want to join it, please register HERE before Tuesday 22 April. The reservation is for 60 people, so “first-come first-served”!
• HS4 conveners, authors and members, particularly ECS, are invited to the Hydrological Forecasting (HS4) sub-division meeting. Wednesday (30th April) 12:45-13:45, Room 2.32.
• Contribute to the HEPEXmusic Spotify playlist!

Feel free to add your favourite song and enjoy listening during EGU – click, listen & add your song!

Our flood forecasts will kick off in “real-time” on Tuesday, together with all our virtual posters!
