本文提出了两步显式有限元法，并成功地应用于求解河流浅水方程。在三节点三角形单元的基础上，采用了流量和水位的线性插值函数。在本文的分析中，考虑了边界构形的处理，它随水面高程的增加或减小而移动。分析的特点进行了总结。
This paper presents the two-step explicit finite element method, which has been successfully applied to solve the shallow water equation of river flow. The linear interpolation functions for both discharge and water elevation have been used based on the three node triangular finite element. In the analysis of this paper, the treatment of the boundary configuration, which moves according to whether the water elevation increases or decreases, is considered. Distinctive features of the analysis are summarised.
