Taking the reach with fluctuating backwater area in jiaokou hydroplant in xiujiang river, guanxi zhuang autonomous region for instance, this paper analyzes the water - sediment characteristics of the fluctuating backwater area, calculates the design level of this reach with samples of level and discharge, etc., and propounds the determination method for the designed lowest navigable level of reach with fluctuating backwater area
以廣西繡江交口電站的變動回水區河段為例，分析了變動回水區的水沙特性，分別利用水位、流量樣本及不同方法計算與分析本河段的設計水位，提出了變動回水區河段設計最低通航水位的確定方法。 -
Based on the topographic features and data of sediment particle size of bed load at the fluctuating backwater reach of liujiaxia reservoir, the streamwise variation and variation process of median diameter of bed load during silting and scouring periods of the fluctuating backwater reach are analyzed, and it can be seen that the turning point for the sediment diameter variation from coarse to fine is located at the outlet of shigou gorge of the fluctuating backwater reach
摘要根據劉家峽水庫變動回水區的河段地形特徵和歷年河床質泥沙粒徑級配資料，分析了變動回水區河段淤積和沖刷時，河床質泥沙中值粒徑的沿程變化和歷年河床質泥沙中值粒徑變化過程，並指出粒徑分佈由粗變細的轉折點在變動回水區寺溝峽峽口處。
