Contributions of runoff identity factors to annual streamflow change rates. (a) Partial annual streamflow change rates due to potential evapotranspiration (PET), hydrothermal index (HI), and runoff coefficient (RC) in the Yellow River (YR), source regions (SR), upper reaches (UR), middle reaches (MR) and lower reaches (LR). (b) Partial annual streamflow change rates due to PET, HI, natural runoff coefficient (RCn) and direct human disturbance (HD) fromĀ P1 to P4Ā (1956ā2016), P1 to P2Ā (1956ā1985), P2 to P3 (1969ā2002), andĀ P3 to P4 (1986ā2016). c, Partial annual streamflow change rates due to PET, HI, RCn and HD between two consecutive yearsĀ during 1956 andĀ 2016.
