文中给出了普遍形式的变动界运动学条件，通过对其进行的量阶分析可知，在宽阔潮间带少域采用该条件是必要的．推导出了任意运动曲线坐标系下普遍适用的二维浅海流体动力学方程组和可变边界运动学条件，从而方便地采用随岸界的运动而自动伸缩的自适应网格方法，来模化具有运动边界的浅海动力学问题．用此模型数值模拟了１９６９年的一次风暴潮，特别包含了黄河三角洲海域的风暴潮漫滩过程
In this paper, the general form of the kinematic conditions of the variable boundary is given. According to the analysis of the order of magnitude, it is necessary to apply this condition in a wide range of intertidal zones. The two-dimensional shallow sea hydrodynamics equations and the variable boundary kinematics conditions universally applicable in arbitrary motion curve coordinate system are deduced, so that the adaptive grid method of automatic telescoping with the movement of the boundary can be conveniently adopted to model Shallow sea dynamical problems with moving boundaries. The model was used to simulate a storm surges in 1969, especially the storm surge floodplain process in the Yellow River Delta
