International Association for Hydro-Environment Engineering and Research

IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

About IAHR

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.

Interested in hosting the IAHR 2023 World Congress?

IAHR Members are cordially invited to submit expressions of interest to host the 40th IAHR World Congress which will be held in 2023.

Expressions of Interest should be submitted to the IAHR Secretariat before December 1st and prospective applicants are strongly recommended to contact IAHR Executive Director, Dr Christopher George, for an informal discussion as a first step.

The IAHR Council will select the Congress venue at its meeting in summer 2018. The forthcoming world Congress will be in Panama in 2019 and in Granada, Spain in 2021.
