摘要:
利用SELFE模型建立长江口水动力盐度三维数值模型，重演了长江口水域潮流过程与盐度分布情况，文中简要介绍了S-Z混合坐标在垂向上的分层方法，并对模拟结果进行了验证、分析，说明在长江口北支盐度始终高于南支，且北支盐度变化幅度也大于南支。
It applies hydrodynamic Model-SELFE to
complete simulation system of 3D current-salinity in Yangtze River. The paper
introduces S-Z coordinates in Vertical Hybrid Coordinates, and compares the
computational results with measured data, showing that the salinity of North
Branch has always been higher than that of South Branch, and the salinity
change rates are also more than that of South Branch.
