Abstract

Abstract

In order to study the wave characteristics in the Sanmen Bay, field observation based on AWAC data acquisition equipment was continued for one year, and the statistical analysis, linear regression analysis was done. Moreover, statistics and spectral variations of waves during the typhoon occurrence were investigated, and the reason for the variations was determined on the basis of wave data collected. The results show that the dominant wave direction and the strong wave direction are both E due to the topography of coastal areas; during the wave observation period, H_1/10 is mainly under 0.8 m, and H_max is 2.71 m; the distribution of wave characteristics is a typical Rayleigh distribution in this region; the wave spectra estimated during Typhoon Talim is double-peaked, and the total wave is a combination of swell and wind sea, when the low frequency swell about 0.08 Hz is in a dominant position and the high frequency wind sea about 0.25 Hz is relatively weak. This study will be important as reference in the design of offshore structures as well as for disaster prevention and mitigation.
