通过对浅海缓坡近岸区大面积波浪场的演化、破碎,近岸流的生成和波浪对潮流场结构影响的研究,提出了波浪应作为这类海岸附近污染物输移扩散的重要动力因素.数值实验证明,在波浪以一定角度斜向入射时,近岸排放的污染物在波浪破碎区内将沿岸输移,排污口在波浪破碎区内这种趋势非常明显.因而在改善近岸环境的研究和污水海洋处置工程的设计中,波浪是不能忽略的动力因素,应加以充分考虑.
Based on the research on the evolution of large-scale wave field and the generation of nearshore flow and the influence of wave on the tidal flow field in shallow coastal gentle slope, the wave should be taken as an important dynamic factor for the transport and dispersion of pollutants near the coast. Numerical experiments show that when the wave is obliquely incident at a certain angle, the pollutants discharged near the shore will move along the shore in the wave breaking area, and the trend of the outlet at the wave breaking area is very obvious. In the design of research and sewage ocean disposal projects, the waves can not be ignored and should be fully considered.
