本文提出了一种考虑二次流影响的明渠水流二维计算方法。在分析的假设中，假设主流和二次流的垂直速度剖面保持相似，并通过它们的合成来表达一般的扭曲速度剖面。该方法已使用现有数据进行了验证。计算方案简单，在微机上进行计算是可行的。
A two-dimensional computation method for open channel flows is developed reflecting the effects of secondary flow. Among the assumptions in the analysis, the vertical velocity profiles of the main flow and the secondary flow are assumed to remain similar, and the general distoreted velocity profile is expressed by the composition of them. This method has been verified using available data. The scheme of computation is very simple so that computation by personal computer is feasible.
