The International Association for Hydro-Environment Engineering and Research (IAHR) has announced that the 2025 Arthur Thomas Ippen Award goes to  Prof. Dr Bernhard Vowinckel, in recognition of his pioneering contributions to sediment transport and multiphase flow dynamics, advancing hydraulic engineering through innovative modeling techniques and interdisciplinary research.

The Arthur Thomas Ippen Award was established by the IAHR Council in 1977 to memorialise Professor Ippen, IAHR President (1959-1963), IAHR honorary member (1963-1974), and for many decades an inspirational leader in fluids research, hydraulic engineering and international co-operation and understanding.

The Award is made biennially by IAHR to one of its members who has demonstrated conspicuously outstanding ability, originality, and accomplishment in basic hydraulic research and/or applied hydraulic engineering, and who holds great promise for continuation of a high level of productivity in this profession.

Prof. Vowinckel joins the list of awardees, becoming the 24th. The award will be presented during the opening ceremony of the 41st IAHR World Congress (IAHR2025) on Monday 23 June 2025, at the Singapore EXPO. The following Ippen lecture will be given during the IAHR General Members Assembly in the IAHR2025 World Congress on Thursday 26 June 2025.
