Abstract

Through the analysis on the observed data and the computation, this paper studies characteristics of the residual current in the Yellow River mouth area in Bohai Gulf. The results show that: The tide-wave system, the seasonal wind and the runoff emptying into sea are the three main factors that influence mainly the residual current in that area. The 3 factors cause their own residual currents in the Yellow River mouth area in Bohai Gulf. The residual current in this ocean area is the result of the superimposition of the aforementioned three residual currents. The residual currents superimposed have the profound influence to the diffusion of the Yellow River sediment flowing into sea.
