浅谈日平均流量与瞬时洪峰流量的换算关系

Preliminary Discussion on the Conversion between Mean Daily Discharge and Instantaneous Peak Discharge

瞬时洪峰流量是中小流域暴雨洪水计算方法研究中非常重要的因素。本文以尼日利亚无资料地区为例,以我国广西省资料做参考,以分析得到的日平均流量与瞬时洪峰流量之间的线性相关关系为基础,根据尼国的日平均流量资料换算得到瞬时洪峰流量,为适应性更好的中铁法的产生提供参考依据,为中小流域无资料地区的暴雨洪水计算提供新的研究思路。

Peak flow is a very important element in the research of the computational method for storm flood in the middle and small watershed. This article took the un - gauged basin of Nigeria for example and made a research on the basis of the mean daily discharge of Nigeria,which referring to the data of Guangxi Province of China,taking the linear relationship between the mean daily discharge and instantaneous peak discharge as base,and got the relevant instantaneous peak discharge of Nigeria. The research provided the basis for the ＂Zhongtie Method＂ and offered a new reseach ideas for the computational method of storm flood in the middle and small drainage basin.
