摘要
推理公式法广泛应用于水文资料缺乏地区小河流的设计洪水计算。阐述推理公式法在青海省的发展与应用,分析其计算的误差来源和处理措施,并以民和县隆治沟河段设计洪峰流量计算为例,利用《青海省水文手册》中的研究成果进行计算,得出隆治沟河段百年一遇的设计洪峰流量为531 m3/s,并与其他计算方法所得结果和已有成果进行比较,其精度符合隆治沟河段下垫面特性和产汇流特性。
Hydrological reasoning formula method is widely used in the design of the hydrological data lack of regional small rivers flood calculation. This paper expounded the hydrological reasoning model in the development and application of Qinghai Province and analyzed the calculation error sources and treatment measures. Taking the calculation of designed flood peak discharge of Longzhi Ditch in Minhe County as an example, it used the research results of the Qinghai Provincial Hydrological Manual and drew the designed flood peak discharge of 531 m3/s for once in a century. Comparing with the results calculated by other methods and the current research results, the precision conformed with the underlying surface and runoff characteristics.
