TL;DR: In this paper, the authors focus on the most common type of IG waves, those induced by the presence of groups in incident short waves, and three related mechanisms explain their generation: (1) the development, shoaling and release of waves bound to the short-wave group envelopes (2) the modulation by these envelopes of the location where short waves break, and (3) the merging of bores (breaking wave front, resembling to a hydraulic jump) inside the surfzone.

Predicting seiche hazard for coastal harbours along the northern and western coasts of France
TL;DR: In this article, the role of incoming bound waves on the generation of seiche amplitudes at a series of French harbours is investigated using the solutions of the WAVEWATCH III spectral wave model to compute low frequency spectra using the (Hasselmann in J Fluid Mech 12(04): 481-500, 1962) nonlinear theory.

TL;DR: In this article, a campagne de mesures, composée d'un houlographe mouillé à 50 m de fond and de trois capteurs de pression déployés dans le port, is described.
