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!

ROBIN: Tracking Climate Change Through the World’s Most Natural Rivers
Hydrological change is one of the clearest signals of climate variability and human impact on the environment. Yet detecting these changes reliably requires robust, long-term data from river basins that are as close to “natural” as possible, with little influence from dams, abstractions, land use change or any other human influences. That’s where the ROBIN project comes in. ROBIN, or the Reference Observatory of Basins for INternational hydrological climate change detection, is a global initiative led by the UK Centre …

Where The River Feeds The Wells: A Story Of Smart Monitoring For Safe Drinking Water Supply
When a river becomes your drinking water When you open the tap in Tarnów, a charming city in southern Poland with a history dating back to the Middle Ages, chances are that most of the water you are about to drink once flowed in the nearby Dunajec River. Yet between the river and your glass lies an invisible world: a network of sand and gravel that filters, delays, and transforms the river’s water before it reaches the wells. This natural …

HydroTalks Podcast: Professor Li Li on big data, water chemistry, climate change and science communication
Welcome to HydroTalks, the EGU HS division’s podcast series. In this episode, we interviewed Prof. Li Li (Li Li – Penn State), leader of the Li Reactive Water group at Penn State University. We talked about her research on using data and models for hydro-biogeochemical processes, river water quality, climate change, and research communication. Her research sits at the intersection of hydrology, ecology, and biogeochemistry. We discussed her research and her efforts to promote women in hydrological sciences. You can …

“What if …?” – Creativity in flood risk management using counterfactual scenarios
Floods are among the most devastating natural hazards, claiming lives and damaging infrastructure. The question of how we can be prepared for these extreme events quickly reaches an almost philosophical level: First of all, what is an extreme event? Second, how can we know what the future will bring? For the last century hydrologists have relied on statistical concepts, which are based on observed streamflow, to assess flood hazard but this approach opens many other questions: Do we believe that …
