Water and sediment conditions at the Yichang-Chenglingji reach

These files provide the water and sediment condition and bankfull area change at the Yichang-Chenglingji Reach of the Yangtze River. To study the channel adjustment of the Yichang-Chenglingji reach after the closure of the Three Gorges Dam, a 1D morphodynamic model is applied to simulate bed erosion and coarsening processes in cases with different bed substrates. The grainsize distributions of the bed substrate in the cases are also included. The excel file “change in bankfull area” includes the data of the average change in bankfull area at the 32 sub-reaches of the Yichang-Chenglingji reach during 2002-2020. The adjustment classes are also indicated by different colors in the file. The excel file “water discharge and sediment load” shows the annual water discharge and sediment load at Qingxichang, Yichang, Zhicheng, Shashi and Jianli stations during 1991-2020, respectively. The excel file “bed substrate in cases” shows the grainsize distributions in Cases A, B, C, D and S of numerical modeling. <br>
