摘　　要：根据特小流域的雨洪特性,分别概论了特小流域设计洪峰流量计算、设计洪水过程线确定、方法(公式)选用与成果合理性分析等。特别提出了不管采用哪种方法(公式)计算设计洪峰流量,均需对特小流域进行水文查勘,并尽量利用实测资料,对各项参数进行分析和检验,使计算成果更符合实际情况。According to characteristics of rainfall and flood in extraordinary small catchments, this paper summarized calculation method of design flood peak discharge and flood process, selection of formula and rational examination, h particularly suggested that hydrological investigation on extraordinary small catchments should be undertaken no matter which formula is selected to calculate the design flood peak discharge. Additionally, hydrometric data should used as much as possible to analyze and verify the parameters, so as to make the calculating result more rational.
