Division on Hydrological Sciences

President: Alberto Viglione (hs@egu.eu)
Deputy President: Maria-Helena Ramos (maria-helena.ramos@inrae.fr)

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!

Current issue of the EGU newsletter

How do you get more people to care for the geosciences – a field that affects and influences all of life itself? Scientists across the EGU network share their stories!

Friedrich Barnikel outlines how, since 2003, EGU brings together scientists and teachers for capacity-building workshops, while Evi Nomikou takes us through EGU’s third Geoscience Day, highlighting volcanic geohazards to over 260 school students.

We also hear from Grace Skirrow who breaks down a seemingly complex subject like fluvial geomorphology and the role that it can play in policy decisions. Meanwhile, geologist Sinelethu Hashibi explains why she’s driven to translate geoscience for isiXhosa-speaking communities. And for those of you fond of card games, don’t miss the launch of QUARTETnary: a game about the geological time scale, developed by Iris van Zelst and Lucia Perez-Diaz and partly funded by the EGU Public Engagement Grant 2021.

Finally, don’t forget to visit our EGU24 page to stay up-to-date with information on the upcoming General Assembly this April. You can also subscribe to receive monthly updates in your inbox at the beginning of each month.
