Founded in 1935, the International Association for Hydro-Environment Engineering and Research (IAHR) is a worldwide, not-for-profit, global, independent members-based organisation of engineers, professionals and researchers working in fields related to the hydro-environment and in particular with reference to hydraulics and its practical application. IAHR was called the International Association of Hydraulic Engineering and Research until 2009. IAHR stimulates and promotes both research and its application, and by doing so contributes to sustainable development, a holistic approach to water resources management, the protection of the environment, and a better water future for all. Activities range from river and maritime hydraulics to water resources development, flood risk management and ecohydraulics, through to ice engineering, hydroinformatics and continuing education and training. IAHR stimulates and promotes both research and its application, and by so doing strives to contribute to sustainable development, the optimisation of world water resources management and industrial flow processes. IAHR accomplishes its goals by a wide variety of member activities, including international networking, events, publications and advocacy and international co-operation. The activities of IAHR are carried out by two full-time professional secretariats with offices in Madrid, Spain, which is hosted by the consortium Spain Water (CEDEX, Dirección General del Agua, Dirección General de la Costa y el Mar, Spain), and in Beijing, China, hosted by IWHR. The governing body of the association is a council elected by member ballot every two years. The current president is Prof. Joseph Hun-wei Lee (Hong Kong, China). The current vice-presidents are: Prof. Amparo López Jiménez (Spain), Dr. Robert Ettema (United States of America), and Prof Hyoseop Woo (Republic of Korea). Dr. Ramon Gutierrez-Serret and Dr Jing Peng are Secretary Generals. IAHR is a Scientific Associate of the International Council for Science (ICSU) and is a partner organisation of UN-Water. International networking platform IAHR provides a world class international networking platform. It engages today’s experts and helps prepare the next generation to respond to the complexities of future challenges. Technical Committees and Working Groups exchange and work on the latest hydro-environment knowledge and innovations, collaborate on emerging and pressing water and environmental engineering issues, and influence research agendas. Institute members belong to a vibrant and global community of organisations, authorities, laboratories, companies, and educational institutions involved in hydro-environment engineering, research, water resources management, practice and application. Young Professionals Networks ensure that new generations of future hydro-environment professionals and researchers have the opportunity to engage, network, and
