１９９６年８月，汾河中下游发生了严重洪涝灾害，鉴于此次洪水范围广、历时长、洪灾严重等特点，为探求其致灾原因和存在的问题，同时也为今后整个流域的规划和治理提供一些依据。在１９９７年初，省水利厅以晋水发［１９９７］２６７号文件下达了研究任务。本文即是针对汾河中下游“９６．８”洪水的产生原因、致灾因素，以汾河干流为主，考虑主要产洪支流文峪河、潇河等，在对汾河水库到汾河入黄口进行全流域性实地调查研究的基础上，对该流域水利工程防洪效益进行分析，通过分析干流及区间洪水，计算出干流区间及主要支流径流系数，同时估算了干流各段河道行洪能力，对现有河道及堤防工程存在的问题提出了治理建议。
In August 1996, severe floods occurred in the middle and lower Fen River. Due to the wide range of floods, long duration of floods and serious floods, the causes and problems of the disaster were explored. Meanwhile, the planning and management of the whole river basin in the future Provide some basis. At the beginning of 1997, the Provincial Department of Water Resources issued its research mission with the document Jinbu Fa [1997] No. 267. This article is aimed at the middle and lower reaches of Fen River, “96.8” flood causes, disaster factors, mainly to the Fen River, considering the main flood tributaries of the Wenyu River, Xiaohe River, Fenhe Reservoir Fenhe into the Based on the field investigation of the Yellow River basin, this paper analyzes the flood control benefit of the water conservancy project in the basin, calculates the runoff interval and the main runoff coefficient of the main stream by analyzing the flood of the main stream and the interval, and estimates the flood discharge capacity , Put forward some suggestions on the existing problems of river courses and dike projects.
