摘要
将岸边划分为点、线两种类型边界，并相应给以观测潮位和法向流为零的不同边界条件，建立了ArakawaE网格中的分潮波方程的一种适定的数值计算方法，并对渤海四大分潮进行了试算。结果证明该方法在目前已知的这一类研究系列中是最为理想的方法。
A well-posed numerical tidal model is suggested. By using the mixed boundary conditions in this paper the cast boundary is alternately divided into two types so that one is composed of lines across which the natural condition of no flow is satisfied and the ther is composed of dots at which the tide elevations are specified. By adopting Arakawa E grids the method has been successfully used to compute the principle constituents in the Bohai Sea.
