Abstract：In recent years,many projects of land reclamation were implemented in Bohai Bay.Shoreline changes will influence the tidal flow in Bohai Bay.The 3D numerical flow model ROMS was verified and calibrated with measured data,and tidal current fields near Tianjin Port in 2003 and 2010 were simulated with the verified model.The features of tidal current near Tianjin Port,the characteristics of tidal current velocities at different levels and changes in tidal current fields caused by reclamation project were calculated and analyzed.The results showed that the tidal current velocity between northeastern Dongjiang Port and Hangu decreased 0.1 to 0.18 m/s in rising tide and 0.1 to 0.15 m/s in ebb tide.The tidal current velocity of northern part of Nanjiang Port decreased 0.05 to 0.1 m/s in rising tide,but decreased 0.05 to 0.1 m/s in ebb tide.The tidal current velocity near Lingang Industrial Area decreased 0.1 to 0.18 m/s in rising tide,and 0.1 to 0.15 m/s in ebb tide.The tidal current velocity near Nangang Area decreased 0.1 to 0.15 m/s in rising tide,and 0.1 to 0.15 m/s in ebb tide.
