Evolution Wave Condition Using WAVEWATCH III for Island Sheltered Area in the South China Sea

Wave conditions around islands in the South China Sea (SCS) are of significant interest due to their importance for marine operations and coastal engineering. Understanding accurately predicting wave characteristics this region crucial. In study, third-generation model WAVEWATCH III is employed examine SCS. According water depth height, sea state island was classified into two categories: typhoon moderate state. Several popular wind input–dissipation source terms (ST2, ST4 ST6) used assess separately. The results validated by field data. ST6 show good performance height states, while ST2 at mean period. For state, gives best with larger correlation coefficients a smaller RMSE. above provide valuable insights effects different on accuracy simulations states. spatial distribution heights also demonstrated ST2, which may be useful assessing structures from large scale SCS Yongle Atoll.
