摘要
基于MIKE 21 SW模块建立了该区域的波浪数学模型,分析了台州湾海域50a 一遇极端情况下的波浪分布特征.结果表明:多海岛地形形成了天然的避风港,各岛屿的背波面波高较小,极端高水位作用时波高均减小至4.2～5 m之间;岛屿一字排开,导致在相同极端风速度的情况下不同风向的影响也不同,其中ESE～SE向来风的影响最大;近岸海域受岛屿阻挡作用和风向影响,流向发生偏转.
Abstract
This study utilizes the MIKE 21 SW module to establish a mathematical model of wave condi-tions in the Taizhou Bay area and analyze the characteristics of wave distribution under extreme conditions that occur once every 50 years.The results indicate that:the natural shelter provided by the islands reduces wave heights on the leeward side,with wave heights decreasing to between 4.2 m and 5 m at extreme high water levels;The islands are lined up,resulting in different effects of different wind directions under the same ex-treme wind velocity,with the greatest effect of ESE-SE incoming winds;nearshore areas are affected by the blocking effect of the islands and the direction of the wind,resulting the flow direction is deflected.
