• Description:

    The course deals with advanced methods and techniques in generation and analysis of waves in physical models. The course will cover analysis of long and short-crested waves, generation of linear and non-linear regular waves, generation of oblique waves and associated laboratory difficulties, generation of long-crested and short crested irregular waves, wave reflections and associated laboratory difficulties, active absorption in flumes and basins, wave groups, bounded long waves and wave generator choice and design.

    The course will be lectures followed by laboratory exercises to get hands on experience with the different methods.

  • Important information concerning PhD courses

    We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 5,000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately three months before start. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.
