International Association for Hydrological Sciences (IAHS)

The International Association for Hydrological Sciences (IAHS) is a global organization dedicated to advancing knowledge and research about water resources and their management. It brings together scientists, engineers, and experts to study aspects like rainfall, rivers, groundwater, and how water impacts ecosystems and societies. By promoting collaboration and sharing scientific findings, IAHS helps improve our understanding of hydrology—how water moves and behaves—ultimately supporting sustainable water management and environmental protection worldwide.
