The Songyu Planning Port Area of Xiamen Port located in the two tidal flow diversion and confluence,has slow flow zone and recirculation zone planning quay frontier waters caused by complex flow regime.The flows of flood tide and ebb tide are very sensitive to the port layout.If shoreline scheme cannot meet the requirements of two shares of water diversion,a large scale recirculation zone in the waters of the quay or the serious back silting of sediment will generate.We carry out 24 tests of physical model,and determine the layout scheme of Songyu Port Area.The field measured data show that the results of physical model test can accurately predict the flow condition after completion of Songyu Port Area.
