摘要
从带源项的圣维南方程出发，根据坡面流特点，分析给出了坡面水流运动方程的基本形式；通过基本的力学分析，指出了通常应用于有支流入汇时的一维明渠流方程存在的问题，并得到了新的方程形式．
Based on the St. Venant equations with source terms, the movement of overland flow was analyzed and a more general form of governing equations for it was established. Furthermore, it is also pointed out that the generally used one dimensional equations for open channel flow with lateral inflow are not suitable for some applications, and a revised form of these equations was presented.
