This will help with writing synthesis papers at a later stage when scientific results are accumulating and it will give our papers high visibility in the IAHS community and beyond.

Online conference with all Working Groups

Last year's online HELPING conference was a success and will be repeated 26 Nov 2024 (13-16 CET) in a new format, addressing some of the suggestions made at the side event at EGU. We now have 29 Working Groups that will be gathered to highlight progress and discuss collaboration. Watch out for the upcoming link in the IAHS enews and the IAHS Calendar, where you can also read about events organized by specific working groups.

HELPING tags in the Digital Water Globe

It is now possible to tag and filter items to relevant HELPING Working Groups (up to 6 per item) in the Digital Water Globe. This will facilitate outreach and finding results from case studies as well as finding peers for networking across the globe.

Open call for new HELPING Chair 

The IAHS Scientific Decades change Chair every second year and an open call will soon be announced. The current Theme leaders will remain another year to ensure sustainability and not loose momentum. Prof. Berit Arheimer steps down by the end of 2024 and the new Chair starts 1 January 2025. Follow the process and check out the Call in upcoming enews.

Helping web pages

All Working Groups now have dedicated webpages on the IAHS website  that you can reach by clicking their titles in the table. You can explore the activities under each Theme, browse through presentations and sign up to Working Groups and suggest new ones. You can also contact the Working Group's Chair directly through a contact form.

The XII^th Scientific Assembly of the International Association of Hydrological Sciences (IAHS 2025) will take place in Roorkee, India from 5 to 10 October 2025.

This important biennial event will provide an opportunity to communicate, exchange and project on all major topics in the hydrological sciences within the framework of sessions organized by all IAHS Commissions and Working Groups as well as the new HELPING Science for Solutions Decade.

This event will use a new forum program, to encourage scientific outlook and interactions between participants. Everyone will get an opportunity to speak in a Forum for the plenum. In addition, there will be fewer but more engaging presentations for the broad community of hydrological sciences, without any parallel sessions.

Key Innovations:

• Plenary Sessions Only – Please note that these are not invited talks. Plenary oral will be selected among the submitted abstracts only presenting challenging research. No parallel sessions ensure full audience engagement and better visibility of speakers.
• Guaranteed Oral Slot – All participants will present their work in the plenary, either through a 15-minute plenary oral presentation or a 1-minute forum oral.
• Visibility for Young Hydrologists – Early career scientists will have a secured platform for visibility.
• Poster with Video Interview – Participants opting for forum contributions will have their research showcased both in-person and via video interviews, shared on the IAHS YouTube channel.

Pre-conference events and training will be highlighted on the website when available.

It is jointly organized by the Indian Institute of Technology Roorkee, in coordination with the National Institute of Hydrology Roorkee, Irrigation Research Institute Roorkee and CBRI–Central Building Research Institute (CBRI) Roorkee.

More information will follow soon.

Latin America is home to unique hydrological systems with some of the largest river basins in the world. The combination of diverse climates, biomes and ecosystems with rapidly growing human footprints caused by urbanization, population growth and land use changes, makes it necessary and urgent to explore hydrological knowledge at the interface of science, policy and practice in water resources. The Advances in Hydrological Sciences in Latin America Special Issue will shed light on the distinctive hydrological features of Latin America, especially the complex challenges and opportunities for sustainable water management in the region. This Special Issue is an outcome of the recent Unsolved Problems in Hydrology Latin America initiative, and it is aligned with our IAHS Science for Solutions Decade HELPING, as we welcome contributions that:

(1) investigate interactions of water resources across different spatial scales,

(2) provide holistic solutions for water security,

(3) engage with hydrological knowledge co-creation.

Special Issue contributions are sought that present, but are not limited to:

• Urban hydrology: Investigating the effects of urbanization on hydrological processes, stormwater management, groundwater issues and climate resilience in urban water systems.
• Hydrology of unique ecosystems: Studying interactions in tropical, high-altitude, arid and coastal ecosystems, including the impacts of deforestation and land-use changes.
• Cross-Border Water Challenges: Offering comparative analyses of water availability, quality and socio-economic impacts on water management across borders.
• Hydrological indices and their application: Evaluating various hydrological and ecological indices to assess drought, floods, water scarcity and ecosystem health.
