We are honored to invite you to the 22nd Congress of theInternational Association for Hydro-Environment Engineering and Research – Asia and Pacific Division(IAHR-APD). The congress will be held in Sapporo fromSeptember 14 to 17, 2020.
The theme of the Congress is “Creating resilience towater-related challenges”. Due to climate change, disasters induced by extreme weather have been increasing
globally and Japan has not escaped from such calamities. To overcome climate change-induced disasters andto create infrastructure that mitigates the resulting
damage and loss, hydro-environmental engineers areexpected to identify factors correlated to these eventsand to propose countermeasures. We encourage all who
are involved in hydro-environmental engineering to contribute to the Congress, which will be a valuable opportunity for researchers and other professionals from theAsia-Pacific region to share experience and knowledge.
We will strive to make the 22nd IAHR-APD Congress apivotal event on addressing climate change. It will behosted by Hokkaido University, the Japan Society ofCivil Engineers and other organizations in Japan.
Famous for its annual snow festival, Sapporo, the capital of Hokkaido, is the fifth-most-populous city in Japan.
Autumn is an excellent time to visit Sapporo, with spectacular fall foliage, salmon returning to spawn, fruits
ripening in the orchards and various harvest festivals
taking place. Take this chance to experience the island'samazing nature and local culture!
