Tsunami in coastal zone due to meteorite impact
Abstract The impact of a meteorite into the ocean surface is a rare phenomenon. However, it can be catastrophic, especially for the coastal area. The aim of the paper is to describe the evolution of the tsunami impulse due to meteorite impact in shallow water, including energy dissipation due to bottom friction and wave breaking. As the exact nonlinear solutions for tsunami transformation with energy loss due to wave breaking are not known, the linearised equations of motion are used and energy loss is parameterised accordingly. To describe the evolution of tsunami impulse in shallow water, the Hilbert Transform technique was introduced. It facilitates considerably the evaluation of the tsunami impulse transformation, its run-up and coast inundation range. Examples are included to illustrate the applicability of the theoretical derivations.
