摘要
流域特征值是计算设计洪水的基本因子 ,正确地量算流域特征值是提高设计洪水精度的必要条件。本文分析了流域面积、流域坡长和流域坡度、流域河长和河道坡度的量算方法及各因子对设计洪峰流量的影响。
Drainage basin characteristics values are the basic factors to account design flood, so correctly computing their values are requirement for improving design flood precision. This paper analyzes all main factors to influence flood peak ,such as , the area of drainage basin, slope and streams ,etc, and respectively calculating approach are introduced.
