吉林省洮南市西部半山区设计洪水计算方法浅析

The analysis for the design flood calculation in semi-mountain area of western Taonan City,Jilin Province

分别以推理公式法、罗氏法、水文比拟法几种常用计算方法,计算洮南市几处小流域设计洪水,对各种计算成果做简单的分析和比较。通过验证,吉林省洮南市西部半山区设计洪水计算宜采用罗氏法计算。

the design flood in several small-sized watershed in Taonai City were calculated by reasoning formula method, Roche method, and hydrologic comparable method respectively ,and their various calculation resuits were analyzed and compared. The results shows the Roche method is appropriate for the design flood calculation in western semi-mountain area of Taonan City of Jilin Province.
