Abstract:
Under the combined action of nonlinearity and dispersion of surface wave, tsunami holds various patterns of wave profiles in offshore region after propagating over a continental shelf of gentle slope. The fully nonlinear and highly dispersive wave model is adopted to simulate the evolution and runup of tsunami from deep ocean to coastal shallow region. Scenarios of extreme tsunami in the South China Sea provide the typical tsunami waveform and velocity field along the coastal region. Experimental and numerical results of the runup of the multi-solitary waves and undular bores will be presented and discussed.
