The three-dimensional hydrodynamic numerical model of the Yellow Sea and the East China Sea has been further utilised to provide S$sub$2/,K$sub$1/,O$sub$1/ tidal currents distribution in addition to previously provided M$sub$2/ tidal current distribution(Choi, 1984), especially the vertical variation of horizontal current in the region. Model results have been compared with current meter data acquired from recent China-USA Marine Sedimentation Dyamics Programme (Larsen and Cannon, 1983). Results were also used to provide maps of the S$sub$2/,K$sub$1/,O$sub$1/ tidal current constants and tidal ellipses at three depths to complement previous M$sub$2/ tidal current information.
