- Аннотация: Typical wavelength of a tsunami in the open ocean amounts to hundreds of kilometers while in the shallow water zone, due to diminishing of the phase velocity, wavelength becomes many times shorter. Moreover, in the run-up zone, due to non-linear effects the wavelength might become even shorter. This is why simple regular grids are not optimal for tsunami simulation. In present study, considering physics of tsunami generation and propagation, we suggest basic principles of specification of numerical grid for physically correct and effective tsunami simulation.
