The upstream reach of the lower Jingjiang stretch of the middle Yangtze River (from Guchangdi to Beimenkou), alternatively the Ouchikou wterway is analyzed based on the field data. Because of the complicated fluvial process, it is necessary to reveal the process mechanisms and present regulation methods. Based on the measured data, this paper analyses the characteristics of fluvial process and reveals the process mechanisms of bars and pools. Through the analysis of waterway condition, the regulation methods are suggested. The results may serve as a reference for future study of the Jingjiang stretch.
