Based on Delft3D software,a three-dimensional model of coupled hydrodynamics and water quality in Shenzhen Bay was established.The measured data were used to verify the simulation results,and the temporal and spatial variation of water quality in Shenzhen Bay was analyzed.The simulation results showed that the concentration of pollutants in Shenzhen Bay was relatively high on the whole,and the concentration distribution was highly sensitive to tidal changes.It was not only affected by the point source strength and discharge of all pollution sources,but also by the tidal dynamics in the bay.The concentration of pollutants gradually increased from the mouth to the top of the bay,and the concentration gradient increased from the outside to the inside.
