IAHS Website Upgrade


Thanks to the amazing team of people behind the design of our IAHS new website, we are so pleased that it has been so positively received. Whilst it may not be perfect, we’re still working on it. The site will be getting new features over the next few months, as we look to expand our presence further. The next feature will require a migration of our website and although this should not take longer than a day to complete, the IAHS will be under construction for most of Thursday 21st September 2023.

Thank you in advance for your patience and continued support.


A Call For Theme Leaders


More than 30 Working Groups have been suggested and, although the call to suggest Working Groups is now closed, you have until Friday, 29 September to sign up to an existing working group (link). The Working Groups are linked to three main themes:

  • HELPING with global and local interactions
  • HELPING with holistic solutions for water security
  • HELPING with cross-cutting goals.

We invite you to apply for the role of Theme Leader for one of the three clusters of Working Groups. Leaders will be appointed biennially during the decade as per the previous IAHS Scientific decades (PUB and Panta Rhei). The role of the Theme Leaders will be to coordinate activities within each cluster of Working Groups, to share information, follow up on progress, arrange meetings and joint activities such as workshops, outreach activities, collaborative publications or projects. They will help and guide the appointed Working Group Leaders, and they will report to the IAHS management team (see figure on organisation below).

To be considered as a potential Theme Leader, please complete this Google Form before 15 October 2023. If you cannot access the online Google form, please contact the IAHS office on [email protected] for more assistance via a .pdf form. Each applicant will be contacted directly via email by the IAHS office and the following documents will be requested;

  • A covering letter no longer than 1 page

Update on the IAHS HELPING Science for Solutions Decade

The next IAHS decade is dedicated to local solutions under the global water crisis. The short name is HELPING, and stands for Hydrology Engaging Local People IN one Global world. Read more in the Concept Note.

HELPING underpins solutions for the water crisis, leaving no catchment or hydrologist behind, in search for scientific evidence to:

·          Accelerate the understanding of the linkages between hydrological processes at local and global scales and their interaction with water resources.
·          Engage with local scientists and societies to learn from local experience, differences in hydrological processes and change around the world, and transfer solutions globally.
·          Synthesise hydrological understanding across the globe and underpin the management of current crises by finding holistic solutions to mitigate future crises.

The Community effort

The decade seeks for a bottom-up process empowered by local hydrologists and scientists using open science and local data/methods when solving local water problems. We envisage that the building of local knowledge and cooperation can inform scientists working under similar situations or facing unexpected events worldwide (e.g. learning from floods or droughts in one catchment will inform hydrologists and water management in other catchments).

After outcomes of several online interactions and workshops during the year, as summarised in the Córdoba document and Vienna document, the new scientific decade was launched during the IUGG General Assembly in Berlin, Germany in July (Fig. 1),  including the selection of a logo (Fig 2.) to represent the decade. The strategic planning document describes how the community’s vision will be translated into action by engaging the IAHS membership. These documents along with comments in the archive of the online Forum are the basis for writing a visionary community paper in HSJ, to which all participants soon will be invited for Author contributions.

Way forward

Some 30 Working Groups have been suggested so far and the call is now closed. You can still sign up to an existing working group until the end of September (link).

The working groups are linked to three main themes:

·          HELPING with global and local interactions
·          HELPING with holistic solutions for water security
·          HELPING with cross-cutting goals

The IAHS management team act as a coordinating Steering Group setting up the structure for the decade to facilitate engagement from IAHS Commissions and Working groups. After mid-September an open call will be announced at the IAHS website for leaders of the three Working Group Themes. Leaders will be appointed biennially during the decade as per the previous IAHS Scientific decades (PUB and Panta Rhei, Fig. 3). The IAHS President Berit Arheimer is leading the initial phase 2023-2024. Everyone who signed up as working group members will be invited to an online meeting in November when the Working Groups will be finalised. Another aim is to wrap-up by the end of the year the IAHS HELPING community paper for publication in HSJ by the end of the year.

A Citizen Science project on hydrological data in Italy: SIREN (Saving Italian hydRological mEasuremeNts)

The availability of long and reliable time series of hydrological measurements is essential for hydrological analyses and research; however, these series are often fragmented and not easily accessible because parts of the measurements are still stored in printed volumes of the Hydrological Yearbooks. For this reason, Paola Mazzoglio (Politecnico  di Torino) and Miriam Bertola (TU Wien) have recently launched a citizen science project to digitize historical hydrological measurements in Italy. The project seeks to involve not only hydrologists but also ordinary people in the crowdsourcing of the data gathering and processing for advancing hydrological research, contributing to the transdisciplinary action of the IAHS CANDHY (Citizen AND HYdrology) Working Group. Anyone wishing to contribute, even with just 10 minutes of their time, can find an easy digitisation tool on the project website.
