摘　　要：波浪斜向近岸传播中由波浪破碎作用所引起的近岸波流体系是近岸非常重要的环境水动力因素,对该区域污染物的运动分布起着重要的影响作用。结合近岸波浪传播的抛物型缓坡方程、近岸波流场数学模型及污染物在近岸波流作用下运动的数学模型,对近岸斜向入射波浪破碎所产生的沿岸波流场中污染物的分布运动过程进行了数值模拟,并结合实验结果对数值模拟结果进行了分析验证。In coastal and offshore areas, the breaking-wave-induced currents induced as waves propagate obliquely to coastal zone are important environmental factors, which play important roles on movement and distribution of pollutants in these zones. Based on parabolic mild slope equation for wave propagating in mild slope zones, the near-shore currents model, as well as model of pollutants movement in near-shore water waves and currents, pollutants movement processes in water waves and long-shore currents, which are induced by inclined incident coastal water waves, were numerical simulated, and the numerical results were validated and analyzed.
