By means of three-dimensional POM model, which computes the eddy viscosity coefficient based on two-order turbulent closed model, the tide and tidal current in the Beibu Gulf are simulated with fine grid. In the computed region, six islands are considered and the bottom friction coefficients are taken to be various values from the difference of sea region. Acquired tidal harmonic constants are compared with that of 81 tidal observatories. The absolute mean error of K1 constituent amplitude is 4.6cm and of the lag is 9°. The absolute mean error of O1 constituent amplitude is 5.6 cm and of the lag is 7°. The absolute mean error of M2 constituent amplitude is 6.2 cm and of the lag is 15°. The tide,tidalcurrent, residual water level and tide-induced residual current, as well as the vertial distribution of horizontal velocity in this sea region are analysed by the simulated results.
