The Water Exchange Numerical Simulation in the Tielu Harbour Haitang´ Bay Sanya

A hydrodynamic model and convection diffusion model of 2D plane is established in this paper, water exchange of Haitang Bay Sanya is calculated, 2 methods include water points trajectory method and conservative substance concentration of tracer are used to study on water exchange capacity of Tielu Harbour. The simulation results show that: Water exchange rate is faster in the initial, and gradually slows down with the time. Distance closer to the gate, the water exchange ability correspondingly stronger. Water exchange in outer port was better than that of the inner harbor. After 15 days, the exchange rates inner and outer harbor were 37% and 67%.
