Numerical Modeling of Current and Wave Interaction in Huanghua Harbor, China

摘要

Waves and currents can affect each other and their interaction is ofrnprime importance in coastal waters. Huanghua Harbor is one of thernmajor harbors for energy output in China, which suffers a strong wavecurrentrninteraction. A 2D hydrodynamic numerical model is set up byrnDelft3D. The well validated model is used to reproduce wave-currentrninteraction on velocity and water level in Huanghua Harbor coastalrnwater. The results indicate that normal waves play a minor role onrncurrent velocity and water level, however, the strong waves have arngreat influence on velocity and its horizontal distribution patterns.rnSignificant velocity variations occur in the head of jetties and along thernjetties where variation of velocity can reach 0.4 m/s, and the averagernwater level notably increases by 3.63~7.93% with the maximum occursrnat low tide level under the strong wave action.
