The Harold Jan Schoemaker Award is granted to the author(s) of the paper judged the most outstanding paper published in the IAHR Journal of Hydraulic Research in the two years preceding the IAHR World Congress.

The award was established in 1980 to recognise the efforts made by Professor Schoemaker, IAHR Secretary (1960-1979), in guiding the Journal of Hydraulic Research in its formative years. 

Who can be awarded?

The Harold Jan Schoemaker Award (hereinafter referred to as the Award) is presented at the biennial IAHR World Congress to the author(s) of the paper judged the most outstanding paper published in the IAHR Journal of Hydraulic Research (JHR) in the two years preceding the IAHR World Congress.

IAHR members and non-members are eligible for this award.

Nomination

The 2025 edition of the Harold Jan Schoemaker Award is currently open for the Editorial Board.

Selection procedure

The awardee(s) will be selected by the Editor of JHR in consultation with the Editorial Board. The awardee(s) will be selected by majority vote of the Editorial Board. The selected candidate(s) must be endorsed by a majority vote of Council conducted electronically.

The awardee(s) shall be notified by the Executive Director in good time so the awardee(s) can attend the Award ceremony at the World Congress.

The award won't be given where the IAHR Council considers none of the nominees is of sufficient quality.

What does the award consist of?

The award will consist of a bronze medal and a certificate.
