| 摘 要： | 本文研究了均匀岸坡地形条件下．规则波及不规则波浪作用下缓坡近岸海域沿岸流的分布规律。采用数学模型与物理模型相结合，分析了波浪要素，地形坡度等因素对沿岸流分布的影响。提出了表征沿岸流分布特征参数的经验公式。研究结果表明，缓坡近岸海域，波浪作用下沿岸流的分布主要受到入射波浪波高、入射角度及地形坡度的影响。不规则波浪作用下沿岸流的速度分布相对平缓。

| Abstract: | Long-shore current induced by regular and irregular wave is studied for a mild slope beach. By combining the numerical model and physical experiment, influence of beach slope and wave factors on the distribution of wave-induced long-shore current are analyzed. An empirical formula is proposed, which describes the characteristics of the long-shore current. It could be drawn from the results that the long-shore current is influenced significantly by the effects of incident wave height, wave angle and beach slope for the near-shore mild slope beach. The cross-shore profile of current velocity induced by irregular wave is smoother than the current induced by regular wave. |
