Master’s level, degree programmes in medicine, dentistry and veterinary medicine = secondcycle
degree/EQF level 7
Doctoral level = third-cycle (doctoral) degree/EQF level 8

on University Degrees)?
Advanced studies


5. Recommended time/stage of studies for completion


-The recommended time for completion may be, e.g., after certain relevant courses have
been completed.


6. Term/teaching period when the course will be offered


The course will be lectured every other year (odd years) in the I period.

7. Scope of the course in credits

5 cr

8. Teacher coordinating the course

Heidi Pettersson

9. Course learning outcomes

The student will learn
- the properties of the surface water waves and to derive and calculate them
- the properties of the wind-generated waves and the factors that affects the growth of them
- to make simplified wave forecasts

10. Course completion methods

Final exam.

11. Prerequisites

Basic Course in Oceanography, Fluid Phenomena and Mathematical methods (MAPU). Also the Timeseries analysis in Geophysics I is recommended to take before or at the same time as this course.

12. Recommended optional studies

The courses Hydrodynamics and Timeseries analysis in Geophysics is recommended. Also Turbulence course (Turbulenssioppi) is a good addition.

13. Course content

The course consists of two parts: linear (small amplitude) wave theory and wind-generated waves.

The following aspects of the linear wave theory are studied:
- the shape of the wave, celerity, group velocity, energy, orbital motion, velocity and pressure fields, the influence of the water depth, surface film, capillary wave, methods to solve higher order theories and Stokes’ drift.

The following aspects of the wind-generated waves are studied:
- the irregular nature of the wind-generated waves and the usability of the linear wave theory, the wave spectrum, the generation of the waves by the wind, the growth of the waves and their dissipation, the factors determining the growth of the waves and the energy balance equation of wind-generated waves.

14. Recommended and required literature

Lecture notes and student’s own notes.

15. Activities and teaching methods in support of learning


Weekly lectures and exercises (individual work). The assistant will keep a record on the tasks done: extra points will be given according to tasks completed. Total hours of the course is 135. 

16. Assessment practices and criteria, grading scale


The grading scale is the standard scale in Physics.
