Since its creation in September 1935, IAHR has evolved to become the international organisation that it is today with more than 4,000 members from all over the world working for the development of water engineering, the protection of the environment, and a better water future for all.

The IAHR 85th Anniversary Summit will celebrate IAHR's extraordinary achievements as the global leader in hydro-environmental research and engineering, and will combine offline conferences in Beijing, China, and online sessions on 14-17 December, live-streamed webinars, lectures and a reminiscent virtual get-together of prestigious IAHR members with the whole IAHR community.

While reflecting on the many outstanding legacies of the past 85 years, the Summit will be a great experience to inform our future.
