The invention discloses a watershed flood response similarity analysis method based on hydrological data mining. The method comprises the following steps: 1) collecting and processing data; 2) dividing flood sessions; 3) associating a rainfall process, and constructing a sample set; 4) analyzing the similarity of the runoff production process; 5) similarity analysis of the confluence process; and 6) analyzing the basin flood response similarity. The invention provides a basin flood response similarity analysis method based on the similarity of runoff production and confluence processes, and the basin flood response similarity analysis method not only conforms to the hydrological basic theory, but also has pertinence. 本发明公开了一种基于水文数据挖掘的流域洪水响应相似性分析方法，包括以下步骤：1)数据的收集、处理；2)洪水场次划分；3)关联降雨过程，构建样本集合；4)产流过程相似性分析；5)汇流过程相似性分析；6)流域洪水响应相似性分析。本发明提出以产流、汇流过程相似为基础的流域洪水响应相似性分析方法，是一种既符合水文基础理论，又具有针对性的分析方法。
