| 摘 要： | 本文在高阶近似抛物化缓坡方程求解大面积波浪场基础上，利用辐射应力的概念建立了波生沿岸流模型。通过与不同斜坡地形条件下具有不同 波高、周期的规则波及不规则波生流的物理模型实验结果比较，验证了数学模型应用的广泛性和正确性。本文着重分析了数学模型中水平涡粘系数的确定，并得出了沿岸流的一些规律性结论。

| Abstract: | Based on the high order approximate parabolic equation for mild slope, the concept of radiation stress is applied to establish the model for wave induced long shore currents. The applicability and validity of the model is verified by experiments both for regular and irregular wave induced currents with different wave height and period under the condition of various slope. The emphasis of the analysis is laid on the determination of the horizontal eddy coefficient. Some laws of wave induced long shore current are obtained. |

| Keywords: | numerical simulation long shore current parabolic mild slope equation |
