Nominations are now being accepted for the IAHS-UNESCO-WMO International Hydrology Prize. 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.

Nominations for the Prize should be forwarded to one of the National Representatives. Any such Representative can be approached, not only the ones representing your country. The list of representatives is found HERE. In addition, National Committees to the UNESCO-IHP or National Hydrological Advisors to the WMO can nominate. All nominations are forwarded to the Secretary General of IAHS for consideration by the Evaluation Committee. The Committee consists of the President and a Vice-President of IAHS and representatives of UNESCO and WMO

Since 2014, two medals have been awarded under the International Hydrology Prize: the Dooge medal and the Volker medal. Both medals are intended to distinguish outstanding achievements by hydrological scientists but with a different focus. The Dooge medal is aimed at fundamental contributions to the science of hydrology, whereas the Volker medal is aimed at outstanding applications of hydrological science for the benefit of society at large. 

More information, including the list of previous awards and the nomination process, is available here.

Nominations for both of the awards should be received by the Secretary General, Jean-Marie Kileshye Onema at [email protected], no later than 31 December 2025.

Nominations are now being accepted for the IAHS Tison and Falkenmark Awards.

The IAHS Tison Award is named in honour of Léon Tison, a former Secretary-General and Honorary President of the International Association of Hydrological Sciences. The Award was established in 1982 and aims to promote excellence in research by young hydrologists. The Award will be granted for an outstanding paper published by IAHS in a period of two years previous to the deadline for nominations. More information, including the eligibility criteria and list of previous awards, is available here.

The IAHS Falkenmark Award was established in 2022 and named in honour of the late Malin Falkenmark, a professor of Applied and International Hydrology. She was best known for her long-standing work and expertise on the sustainable use of water resources to meet human and ecosystem needs. Her work is characterized by pioneering integration of both natural- and social-science approaches in global perspectives. She was particularly known for developing the Falkenmark Water Stress Indicator, concepts of Blue and Green water and Comparative hydrology. The IAHS Falkenmark Award is for best PhD thesis from a nominee who grew up in and recently performed the PhD work in one or more financially disadvantaged countries. More information, including the eligibility criteria and list of previous awards, is available here.

Nominations for both of the awards should be received by the Secretary General, Jean-Marie Kileshye Onema at [email protected], no later than 31 December 2025.

Please save the date for the IAHS Academy which will be held at the Eastern Institute of Technology in Ningbo, China from 12 - 18 January 2026. IAHS Academy application deadline is 15 October 2025. More information and the IAHS Academy application details can be found here. 

The training will involve four short courses held in parallel:

• Hydrological modeling and digital twin technology
• Advanced hydrological monitoring
• Analysis and simulation of rainfall
• Aquifer dynamics and groundwater modeling

A limited number of SYSTA travel awards will be available to attend the event - application deadline of 10 October 2025. More information and the SYSTA application details can be found here.

Professor Blöschl's world-renowned work has significantly advanced our understanding of flood risk reduction, water resource management, flood scaling, and regional process hydrology. His ground breaking research has had a profound impact on global water management practices, earning him this well-deserved recognition.

Stockholm Water Prize: Meet the Laureate on stage with Prof Günter Blöschl, moderated by Pekka Heino is available on YouTube and can be viewed here.

The Stockholm Water Prize has been awarded annually since 1991 by the Stockholm Water Foundation in cooperation with the Royal Swedish Academy of Sciences. The award is presented by H.M. King Carl XVI Gustaf of Sweden, the official patron of the Prize, to individuals and organizations for extraordinary achievements in water-related fields.

Günter served as IAHS President from 2017 to 2021 and currently chairs the IAHS Working Group on Unsolved Problems in Hydrology (UPH). His leadership and dedication to advancing hydrological science have been invaluable to IAHS and the broader scientific community.

We extend our heartfelt congratulations to Günter for this exceptional accomplishment, which reflects not only his individual excellence but also underscores the strength and impact of the global hydrological science community.
