“…This is probably because most traditional sediment transport equations were derived based on the data with relatively low sediment transport rates, but most of the measured q BML values were greater than 1000 tons/day‐m for the typhoon‐induced floods after river incision. In fact, as mentioned in the Introduction Section, Mussetter () also had similar finding for both laboratory and field data.…”

“…Further, a comparison of the measured sediment transport rates with those computed by Samaga et al (1986), Wu et al (2000) and the proposed method was also made. Mussetter (2000) indicated that commonly used equations tended to underpredict the bed material transport capacities in steep, sand-bed streams. Nevertheless, the detailed comparisons for transport equations were not presented in his paper.…”

Most rivers in Taiwan are intermittent rivers with relatively steep slopes and carry rapid sediment-laden flows during typhoon ormonsoon seasons. A series of field experiments was conducted to collect suspended load data at the Tzu-Chiang Bridgehydrological station of the lower Cho-Shui River, which is a major river with the highest sediment yield in Taiwan. The riverreach was aggrading with a high aspect ratio during the 1980s. Because of sand mining and extreme floods, it was incisedand has had a relatively narrow main channel in recent years. The experimental results indicated that typical sedimenttransport equations can correctly predict the bed material load for low or medium sediment transport rates (e.g. less than about1000 tons/day-m). However, these equations far underestimate the bed material load for high sediment transport rates. The effectsof cross-sectional geometry change (i.e. river incision) and earthquakes on the sediment load were investigated in this study. Anempirical sediment transport equation with consideration of the aspect ratio was also derived using the field data collected beforeand after river incision. Copyright © 2012 John Wiley & Sons, Ltd

“…Yu et al, ), which is lower than streams in other arid environments. Many previous studies have showed that rivers in dryland environments sometimes have very high SSCs, typically in the range of 10–200 kg/m 3 with peaks as high as 600 kg/m 3 (Alhamid and Reid, 2002; Alexandrov et al, , ; Beverage & Culbertson, ; Gerson, ; Mussetter, ; Nordin, , Nordin & Beverage, ; Reid et al, 1994; Sharma and Murthy, 1994; Nouh, ; Reid & Frostick, ; Sharma, Vangani, & Choudhari, ; Sharma, ) or even higher. For example, streams in the Loess plateau in China may have SSC over 1,000 kg/m 3 (Chien & Wan, ; Xu, ).…”

Despite a growing interest in the sediment dynamics of dryland rivers, most research has been based on ephemeral streams in endogenic hydrological systems (runoff and sediment transport determined by local precipitation). Less attention, however, has been paid to allogenic and perennial dryland rivers. Here, we report a case study on the suspended sediment dynamics of the Tarim River, an allogenic and perennial river flowing in a very arid environment in China, based on mean daily discharge and mean daily suspended sediment concentration (SSC) over the last 5 decades . Results reveal that discharge and SSCs are predominantly low and have distributions with large positive skewness. The SSC-discharge relationships can be fairly well generalized by power functions, with quite large scatter at extreme (low and high) flow conditions. Marked temporal and spatial variations were observed in the effective discharge for sediment transport. The frequency of the effective discharge ranged from 0.5% to 2% (or an average flow duration of 2-7 days/year), implying that moderate to high flows play an important role in sediment transport. The sediment rating curves show strong hysteresis effects, with 3 types of hysteresis loops observed, clockwise (the most predominant), anticlockwise, and figure of eight. The high potential for bank collapse near the peak and falling limb of the flood hydrograph is the major cause of anticlockwise and figure-of-eight hysteresis loops.
