【摘要】 选取青海省曲麻莱县2个典型小流域为研究对象,采用经验公式法、地区综合法、推理公式法和瞬时单位线法进行了设计洪水计算。通过对相应计算结果进行对比和合理性分析,得出推理公式法和瞬时单位线法的计算结果可信度较高,为无资料地区设计洪水的计算提供一定帮助。更多还原

【Abstract】 This article selected two typical small watersheds in Qumalai County of Qinghai Province as the research object calculated the design flood by using the empirical formula method,the regional comprehensive method,the reasoning formula method,and the instantaneous unit hydrograph method.This study proposed that the reasoning formula method and instantaneous unit hydrograph method were highly reliable based on the comparison and rationality analysis of the calculation results.The research would provide some help for the application of design flood results in non-data areas.更多还原
