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!

Ready for EGU GA 2026?
Most of us are almost ready to go to EGU General Assembly 2026. It will take place on 3–8 May 2026, with more than 21,000 submitted abstracts (presented as orals, posters, and PICOs, onsite and virtual). The EGU-Programme App is ready to be downloaded. Speakers can already upload their material and of course, all of us can start preparing our personal programme (which can be synchronized with the App, very useful tool). For conveners, the last organizational step is to …

Low-cost equipment keeps urban waterway greenhouse gas emissions research afloat
Greenhouse gas emissions from urban waterways Every field scientist knows to never go to the field without ample supplies of duct tape and cable ties. We utilised this notion daily within the University of Bristol’s Watershed Carbon Lab team, as we undertook a 2-year long field campaign across the UK, Europe and China collecting data for our FLF funded ‘Urban Waterways’ project. Rivers are known to be sources of greenhouse gas emissions to the atmosphere, however an understanding of the …

Podcast Launch: History of Hydrology Interviews
“The number one piece of advice I would give anybody is to pick a problem and go after that problem. Ideally, you should pick a problem that requires a lifetime to solve.” Prof. Siva Sivapalan, episode 1 “A lot of greybeards telling us what we should be doing is absolutely the wrong way to do science. Science is anarchic, it’s bottom-up.” Prof. Mike Kirkby, episode 2 “I wrote to the journal editor asking what the record of rejected papers in …

Close the gender gap among EGU awardees: Nominate your women peers
Scientists are often imagined through a narrow and gendered stereotype. This matters because society’s image of scientist shape who is seen, remembered and valued as a role model. When recognition, leadership and awards are skewed towards male scientists, scientists from underrepresented genders are less likely to feel that they belong, or see a future for themselves in the field. In geosciences, this imbalance is especially visible. EGU itself describes its awards programme as a way of identifying role models for …
