海岸区域的波浪引起的污染物的输移扩散存在不同于水流的情况特征。通过物理模型实验研究了不破碎波浪和破碎波浪中污染物输移扩散的混合系数,提出了确定混合系数的方法,给出了不破碎波浪和破碎波浪两种情况下混合系数经验公式,并与他人的结果进行了对比,结果吻合。
The depth-averaged mixing coefficient of pollutant diffusion and dispersion in coastal zone is studied experimentally. The method for the determination of the coefficient is to use the CCD camera photos and the analytical solution of transient source diffusion. The non-breaking and breaking waves are both considered and the formulae for the depth-averaged mixing coefficients are given using the measurement. Comparisons with other results from the literature are made, and the agreement is good.
