We are pleased to reaffirm that the Hydrological Sciences Journal (HSJ) is the official journal of the International Association of Hydrological Sciences (IAHS). 

Published since 1956, the Hydrological Sciences Journal (HSJ) is a globally recognised, peer-reviewed journal dedicated to the advancement of hydrology. It reflects the diverse, international, and interdisciplinary nature of our community and serves as a platform for innovative research, practical applications, and scientific dialogue.

As an IAHS member, you benefit from:

• Free access to HSJ through your IAHS membership if you are from a Financially Disadvantaged Country (FDC) 
• Opportunities to submit your research to a respected, community-driven journal
• Publish in the HSJ for free
• The chance to support and shape the future of hydrological science.

We encourage all members to read, cite, and promote HSJ within their networks, working groups, and committees. Your engagement ensures the continued impact and relevance of hydrological research worldwide.

Thank you for your continued contributions to the IAHS community.

As part of our shared commitment to strengthening collaboration across the hydrological sciences, we are writing to encourage your engagement with the IAHS Digital Water Globe (DWG), if you have not done so already.

The Digital Water Globe is an innovative tool specially designed for, and by, IAHS members. Here you can give visibility to (un)published results, research sites, datasets and find peers for collaborating around the world. It is designed to promote visibility, foster connections, and stimulate interdisciplinary collaboration.

While many IAHS members have received their DWG login credentials, we have noted that some are yet to complete their Personal Profiles or begin using the platform. To fulfil the potential of the DWG and support its growth, we kindly urge you to log in and complete your Personal Profile as soon as possible. Setting up your Personal Profile requires just a few minutes. To assist with this, we have created a set of comprehensive guides, and you will find them on our IAHS DWG webpage. The process is intuitive, and your contribution will ensure your role and expertise are visible within the DWG.

If you have questions or need assistance accessing your account, we are here to help.

The International Conference "Sediment and Pollutants Transport in River Catchments: Radionuclides and Fingerprinting Techniques Applications for Assessment, Monitoring, and Risk Prevention" will be held in Astana, the capital of Kazakhstan, at the Kazakhstan Branch of Lomonosov Moscow State University from 17-21 November 2025:

• 17 November: arrival day
• 18-20 November: conference program
• 21 November: departure day.

The conference will be held in person. Scientists working in the fields of erosion, fluvial processes, and sediment fingerprinting are warmly invited to participate. Click here to find out more about the conference, registration process, and abstracts submission.

The early-bird period, now open until 15 May 2025, offers discounted registration fees for students, delegates, and participants from financially disadvantaged countries (FDC), making it easier for a diverse and vibrant community to take part. Registration includes access to all scientific sessions, plenary lectures, workshops, conference materials, meals, local transportation, and social activities.

We encourage you to secure your spot today and join us for a week of inspiring science, meaningful dialogue, and international collaboration.

Detailed information on registration categories, fees, and benefits is available here.

As we gear up for EGU2025, we are thrilled to unveil our focus on HELPING, the Digital Water Globe (DWG) and the Association. Here's a sneak peek at what we have in store...

The early bird registration for the XIIth IAHS Scientific Assembly in Roorkee this October, is set to close on 30 April 2025. So get your registration in now to avoid any disappointment! 

The International Hydrology Prize is awarded annually by IAHS, with UNESCO and WMO, to two people who have made an outstanding contribution to hydrological science. IAHS is pleased to announce the recipients of the International Hydrology Prize (Dooge medal and Volker medal) for 2025. This year's prize selection was especially competitive, with 15 nominations received, out of which 75% of the nominees were deemed outstanding, making this one of the most distinguished pools of candidates we have ever seen. The 2025 recipients emerged at the top of this highly accomplished group of excellency. Their contributions to hydrology have not only advanced scientific understanding but have also had a significant global impact.

Nominations for the annual Prize are made by National Committees to IAHS, National Committees to the UNESCO-IHP or National Hydrological Advisors to the WMO, and forwarded to the Secretary General of IAHS for consideration by the Nomination Committee. The Committee consists of the President and a Vice-President of IAHS and representatives of UNESCO and WMO.

The 2025 recipients of the IAHS-UNESCO-WMO International Hydrology Prize are:

• Dooge medal - For critical advancements to improve our understanding of climate warming as well as the cryosphere, hydrological processes, and hydrological predictions in cold regions and ungauged basins around the world - Prof. John Pomeroy, at the University of Saskatchewan, Department of Geography and Planning, in Canada. 

• Volker medal - For outstanding original contributions, which have significantly benefited society by addressing critical issues of public interest and development, such as coupled human-flood and human-drought interactions - Prof. Giuliano Di Baldassarre, at the Uppsala University, Department of Earth Sciences, in Sweden.

The award ceremony is scheduled to take place in Roorkee, India during the IAHS Scientific Assembly from 5-10 October 2025. 

We extend our warmest congratulations to the winners and express our deep appreciation to all nominees and nominators. Several of the candidates would undoubtedly have been awarded the prize in any other year, and we encourage renewed nominations in the future. This year’s process clearly demonstrates the value and prestige associated with the International Hydrology Prize and reaffirms its role in recognising the world’s leading hydrological scientists.

We are delighted to share the publication of a major milestone in our scientific community: “Panta Rhei: a decade of progress in research on change in hydrology and society” is now an Open Access paper published in the Hydrological Sciences Journal.

This paper marks the culmination of the Panta Rhei Scientific Decade (2013–2022), a transformative initiative that brought together hydrologists across the globe to explore the dynamic interplay between water and society. 

"Inspired by the IAHS scientific decade “Panta Rhei – Everything Flows: Change in hydrology and society” a vibrant, diverse community of hydrologists, social scientists, and practitioners formed, driven by the aim to better understand changes in hydrology and society. More than 100 people from around the world worked together on this community paper that provides a review of the related progress. A key finding is the need to use integrated approaches to assess the co-evolution of human–water systems in order to avoid unintended consequences of human interventions over long periods of time." said Heidi Kreibich.

On behalf of IAHS, we extend our heartfelt thanks to Heidi Kreibich and to all who contributed to the Panta Rhei initiative over the years. This paper is not only a celebration of what has been achieved, but also a powerful call to action as we continue to evolve our science to meet the needs of society.
