Impact of port planning on hydrodynamics and water environment: case study of Dongjiakou Port area of Qingdao Port

There is a certain view that port planning and construction will cause impact on the marine hydrodynamics and environment to some extent. Two breakwaters and some high-piled wharfs are planning in Dongjiakou Port area of Qingdao Port. Taking the case as an example, the paper established the hydrodynamic model and water environment model to research the impact of breakwaters and wharfs planning and construction on marine dynamics and environment. Simulation results demonstrate that the currents velocity are no longer changing from a distance of 2 kilometers away. The tidal volume is decreasing about 0.07% after the planning implementation. The suspended sediment caused by port construction has an adverse impact on water quality of surrounding waters. The conclusion can benefit for port planning and construction.
