摘　　要：Based on coastal high-resolution (2′X2′) coupled wave-tide-surgeinteraction numerical model, the effects of radiation stress on wave heights and sea level in thecoastal area of Huanghe Delta were studied. By comparisons of simulated and measured wave heightsand sea level for two mediately strong weather cases, it is demonstrated that the results simulatedby coupled wave-tide-surge model are closer to the measured and particularly in excellent agreementin the extreme values of the wave heights and set-up. This study shows that the radiation stress canincrease the wave heights maximally to 67cm and sea level to 40cm. It is also found that there areareas of over 50cm wave height increase and an area of over 20cm sea level increase in the HuangheDelta coastal area, and this find may be very important in engineering. For this reason, it issuggested that in the practical engineering application, the coupled wave-tide-surge interactionnumerical model should be prefered.Based on coastal high-resolution (2′X2′) coupled wave-tide-surgeinteraction numerical model, the effects of radiation stress on wave heights and sea level in thecoastal area of Huanghe Delta were studied.
