The 41st IAHR World Congress, hosted by the International Association for Hydro‑Environment Engineering and Research (IAHR), will take place at the Singapore EXPO, co‑located with the Singapore International Water Week (SIWW) Spotlight 2025.

Themed “Innovative Water Engineering for Sustainable Development,” the biennial conference convenes engineers, researchers, policymakers, practitioners, and young professionals globally to exchange cutting-edge knowledge, foster interdisciplinary dialogue, and explore design and technical innovations addressing climate adaptation, urban and rural water challenges, and the critical water‑energy‑food‑nature nexus. The Congress program features high-level panels on urban resilience, hydropower transitions, digital water engineering, technical and special session streams, workshops, masterclasses, CORE2025 Symposium on coastal resilience, technical visits, and a lively Solutions Marketplace exhibition.
