“…Yeshaneh et al (2013), Fan et al (2013) as well as Gao and Josefson (2012) provide comprehensive overviews of studies that interpret the hysteresis between suspended-sediment concentration (SSC) and discharge (Q). However, hysteresis patterns are ambiguous and typical patterns like clockwise or anti-clockwise loops have been attributed to different phenomena, depending on the characteristics and size of a catchment (Smith and Dragovich, 2009).…”

“…The annual sediment ‘storage–mobilization–depletion’ process may have a profound impact on the shape of the SSC – Q hysteresis patterns (Hudson, 2003; Sun et al ., 2016). Sediment discharge in floods was quite low during both winter and spring (Figure 6), indicating that sediment may be stored during this phase via various mechanisms, involving weathering, degradation, runoff, landslides and sediment inputs from human activities (Fan et al ., 2013). Due to the low proportion of runoff W in this storage phase (Figure 6), the accumulated sediment was not flushed by these small flows and thus remained in the channels.…”

The peak in sediment transport in alluvial rivers generally lags behind the peak in discharge. It is thus not clear how the hysteresis in the sediment/discharge relationship may be impacted by damming, which can fundamentally alter the water and sediment regimes in the downstream reaches of the river. In this study, a total of 500 flood events in the Yichang–Chenglingji Reach (YCR) of the Middle Yangtze River immediately downstream of the Three Gorges Dam (TGD) are analysed to study the impacts of dam operations on the hysteresis of suspended sediment transport. Sediment rating curves, hysteresis patterns, as well as lag times, are investigated to determine the relationship between suspended sediment concentration (SSC) and flow discharge (Q) at different temporal scales, from inter‐annual to individual flood events, for the pre‐ and post‐TGD period from 1992 to 2002 and from 2003 to 2017, respectively. The results showed that the TGD operation decreased the frequency and magnitude of floods. The decrease in peak flow and increase in base flow weakened the flood contribution to the annual discharge by nearly 20%. However, the relative suspended sediment load contribution during flood events was much higher than the discharge contribution, and was little impacted by the dam. At seasonal and monthly scales, more than 80% of the suspended sediment was transported by ~65% of the water discharge in the summer and early autumn. The monthly SSC–Q relationship changed from a figure‐eight to an anti‐clockwise pattern after the construction of the TGD. For single flood events, the TGD operations significantly modified the downstream SSC–Q hysteresis patterns, increasing the frequency of anti‐clockwise loops and the lag time between peak Q and peak SSC. These adjustments were mainly caused by differences in the propagation velocities of flood and sediment waves and the sediment ‘storage–mobilization–depletion’ process, whereas the influence of lateral diversions was small. © 2020 John Wiley & Sons, Ltd.

“…During flood events, the relationship between sediment transport and discharge is not normally homogenous, often producing hysteretic loops (diCenzo and Luk, 1997; D'Agostino and Lenzi, 1999;Rickenmann, 2001;Seeger et al, 2004;Lefrancois et al, 2007;Rodríguez-Blanco et al, 2008;Soler et al, 2008;Mao et al, 2014), which have been identified between discharge and sediment transport on the Loess Plateau (Fang et al, 2008(Fang et al, , 2011(Fang et al, , 2015Fan et al, 2013). However, the role of hysteretic loops for check dams remains unclear.…”
