Abstract: A two-dimensional, depth-averaged hydrodynamic model together with a Lagrangian-type particle tracking model is developed to investigate hydrodynamics and passive particles transport in the Zhoushei estuary, Taiwan. Numerical experiments are performed by means of continuous and single release approaches with different release stages. The analyses indicate that particles being released at a deep water region would not be observed in nearshore region; the effects of both release approaches as well stages are insignificant. However, particles being released at a shallow water region generally transport to nearshore region for both single and continuous release approaches. When particles being transported to the shallow water regions, they are clearly aggregated in the north and south parts nearby the mouth of Zhoushei river during a flood and an ebb stages, respectively. It is also found that during a flood stage a formation of a wake region subject to the presence of Mailiao industrial park plays an important role for a particle move to shallow regions.
