IAHR World Congresses

The IAHR World Congress is one of the most important activities of the International Association for Hydro-Environment Engineering and Research (IAHR) which typically attracts between 800 and 1500 participants from around the World. 

Based on four main themes, the congress offers technical programmes, seminars, technical workshops, presentations, plenary sessions and social events alike, and the respected Ippen, Kennedy and Schoemaker Awards  are presented. This congress is the place for the hydraulic engineering community to meet across borders and exchange experiences, seek advice and get inspired.


IAHR 2023 World Congress application are closed. The call and bidding guidelines to host the 2025 World Congress will be announced before the end of 2019. For more information please contact Madrid Office Manager Elsa Incio at elsa.incio@iahr.org
