The IAHR-Asia and Pacific Division Best Paper Award (hereinafter called the IAHR-APD Award) recognizes the authors of the two most outstanding papers presented at the IAHR-APD Congress. It was established by the IAHR Council in its meeting in Moscow on 3 September 1983 to encourage the presentation of results on hydraulic and water resources research at the IAHR-APD biennial congresses.

1. The IAHR-APD Award will be presented at each biennial IAHR-APD Congress to the authors of the two papers judged the most outstanding papers published in the Congress proceedings.

2. The awardees will be confirmed by the IAHR-APD Executive Committee from the proposals for each award, submitted to the APD Executive Committee by an Award Committee set up by the APD Executive Committee and confirmed by the Secretary General.

3. The Award Committee will review the papers submitted for presentation, assess the manner of presentation by the author and will also seek suggestions for nominations of awardees from the participants in the Congress. The nominations of awardees from the participants in the Congress shall be completed with a clear argumentation (maximum one page) regarding its outstanding quality and why the paper is of such a specific quality that it outweighs the other papers of the considered field.

4. The Award Committee shall submit the nominations to the IAHR-APD Secretary before the closing session of the Congress.

5. One award should be for the author of the best paper from the host country and the other one to the author of the best paper from outside the host country. An award may not be made if the papers in one of the categories are judged inadequate.

6. Awards need not be made during any congress in which the IAHR-APD Executive Committee considers none of the nominees to be of sufficiently high quality.

7. The awards will be presented at the closing ceremony and will consist of a plaque, a certificate and a free one-year IAHR membership where applicable.
