The International Association for Hydro-Environment Engineering and Research (IAHR) - Hong Kong Chapter was founded in April 1997. It has the full support of the sixty year old parent organization,  International Association for Hydro-Environment Engineering and Research (IAHR) which is based in Madrid, Spain. The objectives of IAHR - HK are:

  1. to promote the education, science and practice of hydraulics;
  2. to encourage the application of hydraulics to provide socially acceptable solutions of water related problems;
  3. to facilitate the exchange of ideas and information among academics, practicing engineers, and government;
  4. to promote the development of young researchers in the field;
  5. to encourage and sponsor the training of local engineers and professionals;
  6. to provide a platform for links between the IAHR - HK and industry, government and other organizations;
  7. to facilitate and encourage the participation of activities organized by IAHR.

IAHR-HK 5MD Competition


The International Association for Hydro-Environment Engineering and Research – Hong Kong Chapter (IAHR-HK) invites research postgraduate students (MPhil or PhD candidates or fresh graduates) in the field of hydraulics (including hydrodynamics, hydrology, water resources, and so on) to participate in the IAHR-HK 5MD Competition to be held on February 23, 2019.  The top three scorers of this competition will receive a prize of HK$1,000 from IAHR-HK.


The 5MD, an acronym for 5-Minute-Dissertation, is a competition where candidates contend to explain their research findings in a five-minute presentation to a general audience.  This competition is adapted from 3MT®, which was developed by the University of Queensland of Australia in 2008.


IAHR-HK 5MD Competition shall be conducted in a manner similar to that of HKU 3MT (   In particular, the Presentation Rules and Judging Criteria are as follows.


Presentation Rules

        A single static PowerPoint slide is permitted (no slide transitions, animations or ‘movements’ of any description; the slide is to be presented from the beginning of the oration).

        No additional electronic media (e.g. sound and video files) are permitted.

        No additional props (e.g. costumes, musical instruments, laboratory equipment) are permitted.

        Presentations are limited to 5 minutes maximum and competitors exceeding 5 minutes are disqualified.

        Presentations are to be spoken word (e.g. no poems, raps or songs).

        Presentations are to commence from the stage.

        Presentations are considered to have commenced when a presenter starts their presentation through either movement or speech.

        Presentations should be delivered in English.

        The decision of the adjudicating panel is final.

Judging Criteria

        Did the presentation provide an understanding of the background and significance to the research question being addressed, while explaining terminology and avoiding jargon?

        Did the presentation clearly describe the impact and/or results of the research, including conclusions and outcomes?

        Did the presentation follow a clear and logical sequence?

        Was the thesis topic, research significance, results/impact and outcomes communicated in language appropriate to a non-specialist audience?

        Did the presenter spend adequate time on each element of their presentation - or did they elaborate for too long on one aspect or was the presentation rushed?

        Did the oration make the audience want to know more?

        Was the presenter careful not to trivialise or generalise their research?

        Did the presenter convey enthusiasm for their research?

        Did the presenter capture and maintain their audience's attention?

        Did the speaker have sufficient stage presence, eye contact and vocal range; maintain a steady pace, and have a confident stance?

        Did the PowerPoint slide enhance the presentation - was it clear, legible, and concise?
