Abstract

An astronomical tide and tsunami coupled numerical model of East China Sea was established by adding tidal boundary conditions into COMCOT tsunami model. Two different tsunami waves, positive leading wave and negative leading wave, were designed according to the dislocation direction of earthquake plates during an undersea earthquake with magnitude of 7.6, which occurred in Ryukyu Trench. The tsunami wave crest and astronomic high tide level occurred at the same time through the modification the phase of tsunami wave. Comparison about the summation of astronomic tide level and tsunami wave level was made between the result of coupling model and linear sum. It demonstrates that in both cases mentioned above, the tsunami wave is in advance no matter for the positive leading wave or negative leading wave. And it's higher for the result of linear sum with respect to tsunami wave height.

Key words

COMCOT model / astronomical tide / tsunami / coupling model / linear sum
