In this paper, the framework for sediment deposition in TGR from 2003 to 2017 is analyzed based on field data, its influence factors are discussed, and the empirical equations governing the relationships are presented. The results show that the sedimentation pattern of the TGR is discontinuous and that the perennial backwater area is the key sedimentation area, while the reaches of Xiangxizhen, Wushan, Fengjie, Wanxian, Huanghuacheng, Lanzhuba, and Tunaozi are the main deposition points in the reservoir. These deposition points include meandering and branching channels with the same characteristics of a wide section. Sediment deposition in the TGR is affected by the incoming water and sediment, the operation rule of the reservoir, and by the characteristics of its reaches. Compared with the factors influencing the total sediment retention ratio of the reservoir, local reach conditions are also the main factors influencing the sediment retention ratio of the reaches. The sediment retention ratio can be a good indicator that reflects sedimentation in the TGR; the calculated sediment retention ratio agrees well with field observations. With the continuous construction and operation of the main and tributary reservoirs in the upper Yangtze River, the existing sedimentation framework of the TGR will persist for many years.
