“…Furthermore, clockwise patterns have also been attributed to rainfall of long duration and low intensity, high total runoff and high initial soil moisture. In the latter case, the event is characterized by a first flush of nearby sediment sources, but then rainfall causes an increasing area of the catchment to contribute to the total sediment load, while nearby sources are exhausted (Eder et al, 2010).…”

“…Several studies have developed alternative approaches to construct sediment rating curves such as nonlinear least squares regression (Asselman, 2000) (Figure 2b-d) and generalized linear models (Cox et al, 2008). Furthermore, other studies subdivide calibration data into groups related to seasonality, hydrology or flood limbs to improve the outputs (Eder et al, 2010;Fang et al, 2015). As a result, studies are highly inconsistent (and difficult to interpret) in terms of the relationship between discharge and sediment dynamics (Sun et al, 2015).…”

“…More complex hysteresis patterns have also been observed, such as a single line plus a loop and figure-eight patterns (Sun et al, 2015). The analysis of hysteresis patterns can provide useful insights into the presence of feedback mechanisms and thresholds determining SS transport (Eder et al, 2010;Krueger et al, 2009). While hysteresis patterns are commonly used to express SS dynamics at the event-based scale, they can also be used to visualize seasonal variations in the relationship between SS concentration and discharge (Sun et al, 2015).…”

“…Their results showed that the model performed well in simulating small hysteresis loops, but could not account for the exhaustion of sediment sources due to the variability in sediment transport dynamics (Krueger et al, 2009). Eder et al (2010) tested four methods to calculate instantaneous sediment concentrations in an agricultural catchment in Austria. They conclude that both general rating curves and event-specific rating curves result in considerable scatter for event specific sediment concentrations and total sediment loads.…”

“…The inclusion of parameters related to the rate of change of the discharge to account for hysteresis effects, resulted in improved estimations with 0-1% deviation from the measured SS concentrations. However, the model proved to be unsuitable for high numbers of data points and for complex hysteresis patterns comprising multiple discharge and sediment peaks (Eder et al, 2010).…”

Suspended sediment is a natural part of river systems and plays an essential role in structuring the landscape, creating ecological habitats and transporting nutrients. It is also a common management problem, where alterations to sediment quantity and quality negatively impact ecological communities, increase flood hazard and shorten the lifespan of infrastructure. To address these challenges and develop appropriate sustainable management strategies, we need a thorough understanding of sediment sources, pathways and transport dynamics and the drivers that underlie spatial and temporal variability in suspended sediment transport in rivers. However, research to date has not sufficiently addressed the temporal complexity of sediment transport processes, which is limiting our ability to disentangle the hydro-meteorological, catchment, channel and anthropogenic drivers of suspended sediment transport in rivers. This review critically evaluates previously published work on suspended sediment dynamics to demonstrate how the interpretation of sediment sources and pathways is influenced by the temporal scale and methodology of the study. To do this, the review (i) summarizes the main drivers of temporal variation in suspended sediment transport in rivers; (ii) critically reviews the common empirical approaches used to analyze and quantify sediment sources and loads, and their capacity to account for temporal variations; (iii) applies these findings to recent case studies to illustrate how method and timescale affect the interpretation of suspended sediment transport dynamics; and finally (iv) synthesizes the findings of the review into a set of guidelines for a multi-timescale approach to sediment regime characterization. By recognizing a priori that study design and temporal scale have an impact on the interpretation of SS dynamics and employing methods that address these issues, future research will be better able to identify the drivers of suspended sediment transport in rivers, improve sediment transport modelling, and propose effective, sustainable solutions to sediment management problems.

Quantitative characterization of stream turbidity‐discharge behavior using event loop shape modeling and power law parameter decorrelation

Turbidity behavior in streams is a complex and dynamic function of both source material supply and event-driven transport. While the primary controls on turbidity behavior across time and space are still not fully understood, recent increases in the availability of high temporal resolution, colocated stream turbidity, and discharge data provide an opportunity for more detailed analysis. Here we examine methods to quantitatively characterize event responses by modeling the shape of turbidity-discharge hysteresis loops. A total of 1559 events from 20 gages in the Mid-Atlantic region of the U.S. were modeled using both previously reported models and new models combining elements of existing models. The results suggest that a more general power law-based model, utilizing both a discharge rate of change term and a ''supply'' term, allows characterization of a wide range of simple and complex events. Additionally, this study explores a decorrelation approach to address the strong correlation frequently observed between the power law model coefficient (a) and exponent (b), with the goal of exposing the underlying behavior of each parameter individually. An examination of seasonal parameter behavior suggests that this approach may facilitate greater physically based interpretation of the power law coefficient. The power law parameter decorrelation strategy and the loop models examined here provide a step toward the larger goal of understanding the physical controls on turbidity-discharge hysteretic behavior.

A detailed laboratory study was conducted to examine the effects of particle size on hysteretic sediment transport under time‐varying rainfall. A rainfall pattern composed of seven sequential stepwise varying rainfall intensities (30, 37.5, 45, 60, 45, 37.5, and 30 mm h−1), each of 20 min duration, was applied to a 5 m × 2 m soil erosion flume. The soil in the flume was initially dried, ploughed to a depth of 20 cm and had a mechanically smoothed surface. Flow rates and sediment concentration data for seven particle size classes (<2, 2–20, 20–50, 50–100, 100–315, 315–1000, and >1000 µm) were measured in the flume effluent. Clockwise hysteresis loops in the sediment concentration versus discharge curves were measured for the total eroded soil and the finer particle sizes (<2, 2–20, and 20–50 µm). However, for particle sizes greater than 50 µm, hysteresis effects decreased and suspended concentrations tended to vary linearly with discharge. The Hairsine and Rose (HR) soil erosion model agreed well with the experimental data for the total eroded soil and for the finer particle size classes (up to 50 µm). For the larger particle size classes, the model provided reasonable qualitative agreement with the measurements although the fit was poor for the largest size class (>1000 µm). Overall, it is found that hysteresis varies amongst particle sizes and that the predictions of the HR model are consistent with hysteretic behavior of different sediment size classes.
