Numerical Modeling of Waves and Current in the Bo Sea during the Typhoon of Matsa
The paper presents the research results of both the effect of waves on current and the effect of current on waves by doing numerical modeling of the wave and current fields during the typhoon of Matsa in the Bo Sea in 2005 with two dimensional depth-integrated numerical models. It is found that the right current field including waves-induced current cannot be numerically reproduced using the quasi-wave-current coupling, but by using the complete wave current coupling. And the modeling results show that the waves-induced current moved at speeds, 0.34 m/s maximum, in a belt-like narrow shadow waters along the western shore of the Bo Sea of China. As to the waves modeling, it is found that current velocity, either in shallow water or deep water, has insignificant influence on the wave simulation results while water depth has significant influence but only in the shallow water. Besides, it is found that that both the qusai-and the complete wave-current couplings yield better wave results than the non-coupling. The maximum significant wave height simulated is found about 5 m within the Bohai during the typhoon of Matsa.
