The IAHS community is more than 11,000 strong with members in over 150 countries contributing to the extensive programme of conferences and workshops, online discussions and IAHS publications
IAHS is one of the eight constituent associations of IUGG
IAHS has proudly and successfully coordinated two Scientific Decades, which, amongst other things, set the research agenda worldwide through collaborative forces. After two successful decades, IAHS want to once more boost the community through launching a third topic for collaborative efforts in hydrological sciences: HELPING, created through a participatory community process and by applying strategic planning. The overall aim with a scientific decade is to accumulate knowledge and streamline the efforts so that coherent engagement, sharing and focus accelerate scientific knowledge and understanding of a specific hydrological problem or phenomena. The HELPING Theme and Working Groups, along with their related proposal documents and sign up forms, are now available for you to view and join. If you're curious about the IAHS Scientific Decades and want to learn more, don't hesitate to get in touch with us. Our team is passionate about what we do, and we'd love to share the details with you. Just drop us an email at [email protected], and let's embark on this scientific journey together. Your quest for knowledge starts here!
