Using a dataset up to 49 years long (1954–2002) at Toudaoguai station, this paper provides insight into the characteristics of suspended sediment transport in the Ningxia-Inner Mongolia reaches of the upper Yellow River, at different temporal scales (within-flood, monthly-seasonal and annual). The results show that, in a single flood event, changes in SSC are not simultaneous with changes in discharge, resulting in counterclockwise hysteretic loops, clockwise loops or figure-eight loops. The C–Q loops and sediment rating curves for different seasons have different characters. The diversiform C–Q loops in the Inner Mongolia reaches of the upper Yellow River may be mainly caused by the sediment inputs from tributaries, the different propagation velocity of sediment and water discharge, spatial and temporal storage–depletion processes of available sediment. Since the joint operation of Liujiaxia and Longyangxia reservoirs after 1986, the transport capacity of the Upper Yellow River has been much reduced
