“…In sediment fingerprinting, only the primary sediment source is identified, without providing information about sediment transport rates and the complexity of the pathways (i.e. locations and duration of intermediate sediment storage in the catchment and in the river) (Cooper et al, 2014a;Koiter et al, 2013b;Poulenard et al, 2009). This problem is clearly illustrated by a hydromorphological assessment study of the River Frome (UK) (Grabowski and Gurnell, 2016).…”

“…Recently, studies have demonstrated the promise of spectral reflectance-based (visible and (near) infrared) fingerprinting methods as a quicker and less costly alternative for sediment source apportionment, with considerable potential to expand the temporal resolution of sediment fingerprinting analyses during high-flow events (e.g. Cooper et al, 2014aCooper et al, , 2014bEvrard et al, 2013;Martínez-Carreras et al, 2010;Poulenard et al, 2009;Tiecher et al, 2015).…”

“…The approach A final empirical approach to gain insights into SS dynamics is to compare temporal variations in sediment source contributions to the total sediment load in the river (Brosinsky et al, 2014b;Carter et al, 2003;Cooper et al, 2014a;Fang et al, 2015;Poulenard et al, 2009). Fryirs (2013 noted that information on the preferential delivery of certain sources of sediment and the loss of other sources should be taken into account when assessing sediment delivery within a catchment, because sediment sources may vary between and during high flow events.…”

“…However, research has increasingly highlighted the stochastic and variable nature of each stage of this basic process (Phillips, 2003). In fact, it is this complexity in the field-catchment-river sediment transfer system that makes estimation of the provenance, transport and deposition of sediment in rivers so challenging (Gao, 2008;Poulenard et al, 2009;Rickson, 2014;Sun et al, 2015;Zhang et al, 2013;Zheng et al, 2012). Currently, we are unable to accurately predict SS concentrations in rivers over multiple timescales because we lack comprehensive understanding of how different drivers of SS transport interact over space and time.…”

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.

“…A number of studies have previously used NIR spectroscopy to assess the physical and chemical properties of catchment source materials by linking the spectra with regression models for predicting mineralogical and organic matter (e.g. Hillier, 2001;Poulenard et al, 2009Poulenard et al, , 2012 or geochemical constituents (Elliott et al, 2007;Martínez-Carreras et al, 2010). In this study, however, the absorbance values of the peaks in the NIR spectra were used to provide fingerprints thereby avoiding the need to develop predictive regression models for specific constituents of particulate matter (cf.…”

Keywords:Sediment-bound organic matter Sources Carbon and nitrogen stable isotopes Near infra-red reflectance spectroscopy Salmonids Farm manures A B S T R A C TThe biodegradation of organic matter ingressing spawning gravels in rivers exerts an oxygen demand which is believed to contribute to detrimental impacts on aquatic ecology including salmonids. Catchment management strategies therefore require reliable information on the key sources of sediment-bound organic matter. Accordingly, a novel source fingerprinting procedure based on analyses of bulk stable 13 C and 15N isotope values and organic molecular structures detected using near infrared reflectance (NIR) spectroscopy was tested for assessing the primary sources of sediment-bound organic matter infiltrating artificial Atlantic salmon spawning redds in five rivers across England and Wales. Statistically-verified source fingerprints were identified using a combination of the Kruskal-Wallis Htest, principal component analysis and GA-driven discriminant function analysis. Interstitial sediment samples were obtained from artificial redds using retrievable basket traps inserted at the start of the salmonid spawning season and extracted subsequently in conjunction with critical juvenile phases (eyeing, hatch, emergence, late spawning) of fish development associated with incubation and emergence. Over the duration of these four basket extractions, the overall relative frequency-weighted average median source contributions to the interstitial sediment-bound organic matter sampled in the study rivers ranged between 26% (full uncertainty range 0-100%) and 44% (full uncertainty range 0-100%) for farm yard manures/slurries, 11% (full uncertainty range 0-75%) and 48% (full uncertainty range 0-99%) for damaged road verges, 16% (full uncertainty range (0-78%) and 52% (full uncertainty range (0-100%) for decaying instream vegetation and 4% (full uncertainty range 0-31%) and 10% (full uncertainty range (0-44%) for human septic waste. The results of mass conservation tests suggest that the procedure combining bulk 13 C and 15 N isotope values and NIR spectroscopy data on organic molecular structures is sensitive to the risks of significant non-conservative tracer behaviour in the fluvial environment and will therefore not necessarily work at all in-channel sites in all catchments.
