The M. Selim Yalin Lifetime Achievement Award is conferred upon an IAHR member whose experimental, theoretical, or numerical research has resulted in significant and enduring contributions to the understanding of the physics of phenomena and/or processes in hydraulic science or engineering and who has demonstrated outstanding skills in graduate teaching and supervision.

This award was established in 2006 to honour the memory of Professor M. Selim Yalin (1925-2007), Honorary Member and Fluvial Hydraulics Committee Chairperson (1986-1991), remembered for his prolific and pioneering research contributions in fluvial hydraulics and sediment transport, and for his inspirational mentoring of students and young researchers.  

Who can be awarded?

The IAHR M. Selim Yalin Award (hereinafter referred to as the Award) is conferred biennially, in odd-numbered years, upon an IAHR member whose experimental, theoretical, or numerical research has resulted in significant and enduring contributions to the understanding of the physics of phenomena and/or processes in hydraulic science or engineering and who has demonstrated outstanding skills in graduate teaching and supervision.

No individual shall receive the Award more than once.

Nomination

To submit a nomination please donwload the form and send it to awards@iahr.org by 31 January 2025. 

Selection procedure

Each awardee will be endorsed by the IAHR Council from a recommendation by the IAHR Awards Committee (hereinafter referred to as the Award Committee), either at its meeting during the preceding even numbered year or by e-mail ballot in the year of the Congress in time to encourage the recipient to attend the IAHR World Congress.

The award needs not be made during any biennium in which the IAHR Council considers none of the nominees to be of sufficient high quality.

When and where will the award recipient be announced? 

Public presentation of the Award will be made by the President during a public ceremony taking place at the IAHR World Congress.

What does the award consist of? 

The awardee will be given a suitable certificate which will state the purpose of the Award and indicate the specific contribution(s) of area(s) of endeavour for which the awardee is recognised. The awardee will also receive a monetary honorarium, the terms of which will be published in the announcement of each biennial Award.

The Award fund, which was established by the family and friends of Professor Yalin, is authorised to receive contributions from association members and friends of Professor Yalin.
