Numerical Research on the Changes of Tidal Waves Due to Mean-Sea-Level Rise in the Bohai Sea,the Huanghai Sea and the East China Sea I: Numerical Modeling of Current Tidal Waves in the Areas

Current tidal waves in the areas were modeled by using the spherical tidal wave equations with the tide-generating force taken into account,and with an open boundary condition taken as forced tidal elevation.The modeling covered 19 tidal constituent waves with the largest theoretical coefficients,including,10 semidiurnal and 9 diurnal constituents.This was the first attempt at modeling so many tidal constituent waves.The modeled results were compared with observed data.Co-tidal charts were drawn based on the modeled harmonics,and the movements of the tidal waves were discussed and analyzed.
