Abstract: To enhance the numericl research of tidal current in the East China Sea, the bottom friction in Finite-Volume Coastal Ocean Model (FVCOM) is improved and the tidal wave system of Yellow Sea and Bohai Sea is simulated. The harmonic constants, tidal elevation and tidal current are validated by observation of 37 gauge stations and 3 current stations, showing a good agreement with the observations. The co-tidal chart, current ellipse, Euler residual chart and distribution chart of tidal current property are drawn by quasi harmonic analysis. There are four amphidromic points and eight current- amphidromic points in the simulation area. The tide in model domain is mainly found to be semidiurnal tide, while the diurnal tide is observed at Qinhuangdao offshore, Haizhou Bay offshore, and coastal old Yellow River delta. The current is primarily semidiurnal current, and the diurnal current is located at southeastern Bohai strait.
