The Hydrological Sciences (HS) Division is concerned with all aspects of the terrestrial hydrological cycle (including precipitation, surface water, soil water, groundwater) from the pore scale to the global scale, and its relationships and interactions with the atmospheric part of the hydrological cycle. The division also covers the interaction between hydrology and geomorphology (e.g., erosion, sedimentation, groundwater systems), the relationships between hydrology and soils, as well as the interaction between the hydrosphere and the biosphere (e.g., ecohydrology, wetlands). The ways in which hydrological processes are observed, quantitatively computed, and forecasted are also addressed by the division. Management and operation of water resources by societies in various parts of the world is also within the division's realm.
The Hydrological Sciences Division (HS) has five main tasks:
- Organizing the hydrological part of the program during the annual EGU General Assembly
- Running its on-line open access journal: Hydrology and Earth System Sciences (HESS)
- Recognizing deserving colleagues in various stages of their careers with its Award program.
- Encouraging the interaction and active participation of young hydrologists within the hydrological community
- Circulating news, information, job adverts, announcements of opportunity or meetings that may be relevant to the hydrological community
Such tasks require considerable (voluntary!) input from many people, and offer plenty of opportunities to become actively involved.
To ensure that the sessions during the General Assembly cover our science as comprehensively as possible, there are currently ten Subdivisions, including a subdivision on general hydrology (monitoring and cross cutting issues). Distinct fields within the broad area of hydrology are covered. Each Subdivision Committee organises a set of oral, poster or PICO sessions to cover its field. The members of the Subdivision Committees meet during the EGU General Assembly and start preparing the draft programme for next year’s meeting in late spring/early summer. Membership of the committees of these Subdivisions is open: you can e-mail the Subdivision Committee Chair to request membership or you may directly join the meeting during the General Assembly to get involved in the Subdivision activities and in particular in the organisation of the programme, including proposal of sessions and volunteering as convener or co-convener (see overview of Programme Organisation and Convener Tasks).
You can also become involved in the Hydrology and Earth System Sciences (HESS) journal. In addition to submitting your best scientific work to HESS, consider that the journal needs both referees and members of its Editorial Board to cover a sufficiently broad spectrum of expertise to adequately handle all incoming papers. If you would like to become active as a referee or as an editor you may therefore consider informing any editor or Executive Editor of your wish.
The Division contributes to the EGU Awards & Medals programme that recognises every year eminent scientists for their outstanding research contribution and identifies the awardees as role models for the next generation of young scientists to foster geosciences research. In particular, members of the Division are invited to contribute to the nominations (deadline are every year on the 15th June, see here) for both the young and senior HS Division Awards and Medals (link).
The EGU offers a platform for young scientists to become involved in hydrological research, through sessions, social events and short courses at the annual General Assembly in April. Several activities are especially aimed for Young Scientists in the Hydrological Science, organised with the help of the Young Hydrologic Society.
Lastly, you are invited to share the news/information that may be of interest to the EGU Hydrological Sciences community, by sending a tweet to @EGU_HS or filling in the activity calendar webform.
Do not hesitate to contact the Division President or any Division Officer if you need any additional information on our activities!

EGU General Assembly 2026 – A Hydrological Wrap Up
The EGU General Assembly (GA) 2026 was an amazing success! Over the course of five sunny days in Vienna, 20,173 presentations were given across 1,014 sessions by the 20,027 on-site participants and 2,470 online attendees. There were plenty of events to choose from for the hydrologists attending. Across sessions, networking events, short courses, posters and medal lectures, we have put together some highlights for you to wrap up a fantastic GA 2026! HS Division highlights As every year, the Hydrological …

Reclaiming scientific publishing: Our duty to make science freely accessible to all
When we (Camille Thomas and Romain Vaucher speaking) entered academia as graduate students in France and Switzerland, we were enthusiastic about the vast amount of research available with a simple click on our university computers. However, we also quickly felt disheartened by the significant amount of research work we couldn’t access when wrapping up our theses from home. Luckily, pirates existed. Empowered by Aaron Swartz’s Guerilla Open Access Manifesto, Alexandra Elbakyan created Sci-Hub in 2011, the greatest leak of scientific …

Regarding Flowing Waters – The Science and Art of Hydrology
About a decade ago, I formally retired from Lancaster University (albeit retaining an emeritus position and still producing the occasional paper). In that time, I have been able to pursue my interests in the history of hydrology but also devote more time to my other passion which is landscape photography, especially images of water. As a hydrologist, I do understand that to spend my spare time photographing water is definitely on the rather sad side of social behaviour but, on …
