摘要
对于顺直河道漫滩水流,本文在总结现有的滩槽流量分配计算方法的基础上、提出了两种新的计算方法—断面叠加法和谢汉祥修正法。室内及野外资料的验证表明,本文方法具有较高的精度。
The existing methods of computing the discharge distribution of overbank flow have been summarized in this paper. Due to the lower precision of hydraulic computation for a compound cross-section with two flood plains, two new mefhods have been given and verified with experimental and field data. The result shows that the new methods are more satisfatory than others.
