Wave Trapping Around Islands


Islands are subject to tides, seismic waves as well as wind generated waves. If any of these are trapped, that is the energy of the wave goes continuously around the island without escaping then there are practical consequences in terms of flood prediction as well as the detection of signals of say earthquakes or the effects of distant storms such as hurricanes. The effect of the earth’s rotation is also important if the island is large. This project examines models of wave trapping and derives a condition that governs where it occurs dependant on the geometry of the island.
