A Green's function for a semi-infinite rotating ocean of uniform depth is obtained, and the resulting near and far fields are estimated asymptotically.Given a tide of uniform height at the mouth of a narrow channel on a semiinfinite ocean, the Green's function is used to calculate the diffracted Kelvin and Poincare waves propagating up the channel and into the ocean.read more

Tides in gulfs
TL;DR: In this article, the authors interpreted the tidal response of a gulf as a three-stage process: (i) direct forcing produces separate responses in the gulf and ocean, treating the mouth of the gulf as closed, (ii) the difference in elevations VG and VO at the mouth causes a mass flux = (VO − VG) (ZO + ZG)−1 through the entrance, where ZO, ZG are impedances, and (iii) this mass flux produces a response in both gulf and oceans.

A theoretical study of large sea level oscillations in the western Mediterranean
TL;DR: In this paper, the authors used a model with a flat shelf and a sloping bottom harbor, and found that these oscillations were the result of a three-way resonant coupling between an atmospheric gravity wave, a coastally trapped edge wave, and the normal modes of a harbor.

Kelvin waves on oceanic boundaries
TL;DR: In this article, the effects of the Earth's curvature, the reduction in depth over the continental shelf, and bends in the coastline on the primitive Kelvin wave were investigated for coastal propagation of the tides; numerical examples are given for the California coastline.

Tides off‐shore: Transition from California coastal to deep‐sea waters‡
TL;DR: Tidal pressures and currents were measured with self-contained capsules dropped to the sea floor for one month at distances of 175, 190, and 500 nautical miles from San Diego as mentioned in this paper.

Diffraction of Kelvin waves at a sharp bend
B. A. Packham,W. E. Williams +1 more
TL;DR: In this paper, a closed form solution for the linearized problem of the diffraction of Kelvin waves by a sharp bend on a rotating earth was obtained. But the solution was not suitable for the case where the wave is transmitted around the bend without change of amplitude, and the amplitude is in general reduced for the special angles π/(2n + 1).
