Wave Effects on Inlet and Bay
Harbor entrances are usually designed for protection against wind and swell waves (periods of 5-20 s). However, many harbors experience water agitation problems caused by long waves with periods longer than 30 s. Port of Bayonne, located in SW France, is a channel harbor situated near the river mouth of the Adour. Long-period oscillations have repeatedly caused snapping of mooring lines of berthed ships and have led to resonance of adjacent marina (seiche). Field campaign and Boussinesq numerical model were carried out to investigate the hydrodynamic behavior of Port of Bayonne and mechanisms for generation of external forcing.
