用物理模型实验和数学模型计算相结合的方法 ,研究了均匀缓坡岸滩上 ,规则波及不规则波浪作用下形成的沿岸流及其对岸边排放污染物输移扩散的影响。针对渤海湾的地形和主要波浪方向 ,研究了渤海湾主要排污口附近单纯波浪以及波浪、潮流共同作用下近岸海域内流动速度分布与相应污染物输移扩散规律。结果表明 ,在渤海湾近岸海域 (一定范围内 ) ,污染物输移扩散受到波浪作用的影响 ,表现为平行岸线方向。波浪作用使得远离污染物排放口的滩涂受污染的影响增大。
The physical model experiment and mathematical model calculation are combined to study the influence of the coastal flow formed by the regular wave and the irregular wave on the coast of a uniform gentle slope and its transport and diffusion to the pollutant on the shore. According to the topography and the main wave direction of the Bohai Bay, the flow velocity distribution and the corresponding transport and diffusion of pollutants in the coastal waters under the interaction of simple waves, waves and tidal currents near the main outlet of Bohai Bay were studied. The results show that in the offshore area of Bohai Bay (within a certain range), the transport and diffusion of pollutants are affected by the wave effect, showing the parallel shoreline direction. The wave effect increases the impact of contaminated beaches that are far from the discharge of pollutants.
