Paper Number: ISOPE-I-23-347
... frequencies while the energy content of the sea state remains unaltered. Different from unimodal seas, swell components in bimodal seas show different characteristics of wave transformation and energy transfer on beaches because swell waves have a longer period compared with wind waves. In this paper...

... ABSTRACT In order to study the effect of the wind wave for the wave height distribution, we take a port project as an example. The wave height distribution was calculated by using the MIKE 21 BW module and small wave wind wave calculation formula. The result shows that, when the wind direction...

... is applicable even to obliquely long-period waves in the basin. As the incident angle is larger, the reflection coefficients slightly increase for wind waves and swells as unexpected, though they decrease for longperiod waves. Moreover, it is verified that such wave reflections can be reproduced in calculations...

... OF INFRAGRAVITY SEA WAVES It was shown experimentally that oscillations of the Earth s crust in the range of periods greater than 20 s are caused predominantly by the infragravity sea waves (hereafter, IGWs) closely related to wind waves in the sea rather than pulsations of the atmospheric pressure. It has long...
