In this paper,a2 D bi-directional wave-current coupled model in Haitan Bay was set up based on the MIKE21 SW wave module and FM current module.The effects of wave and current interactions were incorporated by extracting the radiation stresses from wave simulations into FM model,and extracting the water levels and velocities from flow simulations into SW model,respectively.The flow fields and wave fields in Haitan Bay under pure current and pure wave condition were simulated respectively,and calibrated by th...
