经验相关图法在洪水预报中的应用分析

在一些下垫面环境特殊的流域,由于其下垫面构成种类、分布的特殊性,对雨水的下渗、汇流会产生较大影响,有时传统预报方法难以满足流域洪水预报要求。文章采用传统相关图法对受冻土影响流域洪水预报方法进行了分析探讨,采用物理成因明确的预报因素建立经验相关关系,对受冻土影响流域洪水预报方法进行了尝试应用分析。

In some watersheds with special underlying surface environment,because of the particularity of its underlying surface composition and distribution,the infiltration and confluence of Rain Water will be greatly affected,and sometimes the traditional forecasting methods are difficult to meet the flood forecasting requirements of the basin.In this paper,the traditional correlation map method is used to analyze and discuss the flood forecasting method in the basin affected by frozen soil,and the empirical correlation relationship is established by adopting the forecasting factors with clear physical cause of formation.The flood forecasting method in the basin affected by permafrost is analyzed in this paper.
