Abstract
Creating, enlarging and excavating a harbour can modify the dynamic response of the basin. A verification of the resonance modes is common practice before undertaking the related work. This can be done numerically if the necessary assumptions are justifiable. It can be done on a small-scale model if the basin has an irregular shape or if the depth varies from one area to the other.A computer-programmed analytical method of resonance modes is presented. It is derived from the direct measure principle of successive oscillation superposition used in the laboratory. Validation is obtained by applying the method to existing theoretical solutions and to the analysis of a small creek of the Gaspe Peninsula where the importance of refraction in the analytical results is demonstrated. Key words: harbour, vibration, agitation, ocean waves, diffraction, refraction, numerical model, application. [Journal translation]
