近岸海域潮，波，波流共同作用下污染物迁移转化规律

Based on the mechanism experimental study in laboratory and the numerical.modeling, the effects of wave–current on pollutant diffusion and transport in the near-shore area has been investigated. The technique to make the wave breaking at fix point and PIV, LIF for measurement the velocity field and pollutant concentration field at same time have been developed in wave flume. The vertical structure of wave and current interaction and the change of the field of pollutant diffusion coefficient in time and space domain have been studied. The longshore current experimental model has been set up in wave basin. The near shore current and the low frequency wave.have been measured and the pollutant transport acted on longshore current was observed in the wave basin. A set of numerical models for the shallow water waves have been developed and improved. The vertical structure model of wave-current interaction and the multiple parameters water quality model for combine the wave and current have been curried out. The numerical models have been used to simulated the aquatic environmental problem in Hakata Bay in Japan and Bohai Bay in china.successfully. The study of the pollutant transport acted by water waves for the near shore area of Bohai Bay will give valuable results for the improvement and restoration of the eco-environment of Bohai Sea.
