However, the degrees of erosion are not the same in different segments of the braided reach between HYK and GC. Table 2 lists the segmented erosion and deposition volumes of the braided reach during the different periods. The cumulative erosion volume in the braided reach amounted to approximately 11.470×108m3 between 2000 and 2017, of which 64% came from the HYK-JHT reach and 36% came from the JHT-GC reach. This is mainly due to the gradually weakened erosion ability caused by the fading kinetic energy from the runoff (Kong et al., 2015).
