With rectangular coordinates system and rectangular grid technology,ECOMSED model is applied to the movement tracking simulation experiment of particles in the Jiaozhou Bay.Based on the 3-D Hydrodynamics module of ECOMSED model,the tracking model of conservative particles is established to simulate the movement tracking of floaters in the Jiaozhou Bay.From the experiment,the movements tracking of contamination from sewerage diffusers in the Bay on the surface layer,middle layer and bottom layer are indicated which can provide environmental gist for choosing sewerage diffusers'location and solving the pollution problem from land,in order to reduce the pollution in the Bay and its adjacent sea area.The horizontal and vertical structures of the 3-D tidal current field and the horizontal distribution of a few of current eddy are obtained by simulation in the Jiaozhou Bay and its adjacent sea area.And the computed results match well with the observations.The particle tracking simulation's result indicates that the movement tracking of particles is in accord with the velocity vector of tidal current,that is to say the movement tracking of particles is related to the tidal current field in the Bay.The released time of particles affects the movement.The particles are easy to excurse to the outer of the Bay when they were released in the time of high tide.
