摘要
Abstract
Driven by typhoon model wind field, American NCEP (National Centers for Environmental Prediction) wind field and combined wind field, respectively, the wave simulation results based on the third-generation wave model SWAN (Simulating Waves Nearshore) are compared with field data. The results show that combined wind field is better than the other two wind fields, which has good simulation both in and away from the typhoon center. The combined wind field is chosen to drive the model, which stimulates 210 typhoons in southeast coast from 1982 to 2015. The numerical simulation results are used to plot P-Ⅲ curves, and they are in good agreement with field data. On this basis, once-in-100-year wave height distribution maps are plotted in different directions, which could provide a reference for offshore project environmental assessment and design.关键词
