“…In general, clockwise hysteresis patterns are attributed to a fast response system (short distances between sediment source and receptor), because the peak in SS concentration typically precedes the maximum discharge of the event. Fast response systems are characterized by rapid sediment flushing and depletion in the river network, because of a limited supply of readily-available material for transport (De Girolamo et al, 2015;Fan et al, 2012;Fang et al, 2015;Francke et al, 2014;Sun et al, 2015;Tena et al, 2014).

“…Furthermore, erosion hotspots such as gullies can form on fields during storm events, causing an increased contribution of sediment from from a specific source. Finally, during individual precipitation events, the sediment supply from a particular source can become exhausted or diluted during persistent high discharges, or other sediment sources might become more connected to the river over time (Fan et al, 2012;Francke et al, 2014;Martínez-Carreras et al, 2010;Poulenard et al, 2012).…”

“…Increase in sediment loads can result from a greater sediment supply, e.g. as a result of soil erosion due to intensification of land use, mining and mineral exploitation or construction works (Fan et al, 2012;Fuchs et al, 2011;Gao et al, 2015;Mohr et al, 2014;Sun et al, 2015;Zhang et al, 2009). …”

“…Change points are abrupt alterations in the sediment regime caused by drastic changes in one or more of the drivers that affect sediment production and transport (Huang et al, 2013;Wohl, 2015). Therefore, assessing long-term sediment regime alterations not only provides insights into the impact of climatic changes on discharge and corresponding sediment loads, but also into the impact of human interventions (Fan et al, 2012;Francke et al, 2008;Horowitz, 2008;Smith and Blake, 2014;Stone et al, 2015;Sun et al, 2015).…”

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.

Near‐Channel Versus Watershed Controls on Sediment Rating Curves

Predicting riverine suspended sediment flux is a fundamental problem in geomorphology, with important implications for water quality, land and water resource management, and aquatic ecosystem health. To advance understanding, we evaluated environmental and landscape factors that influence sediment rating curves (SRCs). We generated SRCs with recent total suspended solids (TSSs) and discharge data from 45 gages on 36 rivers throughout the state of Minnesota, USA. Watersheds range from 32 to 14,600 km2 and represent distinct settings regarding topography, land cover, and geologic history. Rivers exhibited three distinct SRC shapes: simple power functions, threshold power functions, and peaked or negative‐slope functions. We computed SRC exponents and coefficients (describing the steepness of the relation and the TSS concentration at median flows, respectively). In addition to quantifying watershed topography, climate/hydrology, geology, soil type, and land cover, we used lidar topography to characterize the near‐channel environment upstream of gages. We used random forest models to analyze relations between SRC parameters and attributes of the watershed and the near‐channel environment. The models correctly classify 78% of SRC shapes and explain 37%–60% of variance in SRC parameters. We find that SRC steepness (exponent) is strongly related to near‐channel morphological characteristics including near‐channel relief, channel gradient, and presence of lakes along the local channel network, but not to land use. In contrast, land use influences TSS concentrations at moderate and low flow. These findings suggest that the near‐channel environment controls changes in TSS as flows increase, whereas land use drives median and low flow TSS conditions.

Temporal variation in suspended sediment transport: linking sediment sources and hydro‐meteorological drivers

Suspended sediment concentrations (SSCs) in rivers are variable in time due to interacting soil erosion and sediment transport processes. While many hydro‐meteorological variables are correlated to SSCs, interpretation of these correlations in terms of driving processes requires in‐depth knowledge of the catchment. Detailed sediment source information is needed to establish the causal linkages between driving processes and variations in SSC. This study innovatively combined sediment fingerprinting with multivariate statistical analyses of hydro‐meteorological data to investigate how differential contributions of sediment sources control SSC in response to hydro‐meteorological variables during high‐flow events in rivers. Applied to the River Aire (UK), five sediment sources were classified: grassland topsoil in three lithological areas (limestone, millstone grit and coal measures), eroding riverbanks, and street dust. A total of 159 suspended sediment samples were collected during 14 high‐flow events (2015–2017). Results show substantial variation in sediment sources during high‐flow events. Limestone grassland and street dust, the dominant contributors to the suspended sediment, show temporal variations consistent with variations in total SSC, and are correlated with precipitation and discharge shortly prior and during high‐flow events (i.e. fast mobilization to and within river). Contrarily, contributions from millstone and coals grassland appear to be driven by antecedent hydro‐meteorological conditions (i.e. lag‐time between soil erosion and sediment delivery). Riverbank material is poorly correlated to hydro‐meteorological variables, possibly due to weak source discrimination or the infrequent nature of its delivery to the channel. Differences in source‐specific drivers and process interactions for sediment transport demonstrate the difficulty in generalizing sediment transport patterns and developing targeted suspended sediment management strategies. While more research is essential to address different uncertainties emerging from the approach, the study demonstrates how empirical data on sediment monitoring, fingerprinting, and hydro‐meteorology can be combined and analysed to better understand sediment connectivity and the factors controlling SSC. © 2019 John Wiley & Sons, Ltd. © 2019 John Wiley & Sons, Ltd.
