Bedload tracing with RFID tags in gravel‐bed rivers: Review and meta‐analysis after 20 years of field and laboratory experiments

“…This was done by considering the peak discharge between two tracer surveys relatively close in time. Many scaling laws of that type have been reported from event‐based RFID tracing studies in different fluvial environments (Arnaud et al, 2017; Gilet et al, 2020; Houbrechts et al, 2015; Lamarre, Roy, 2008b; Papangelakis, McVicar, et al, 2019; Peeters et al, 2021; Rainato et al, 2020; Schneider et al, 2014). The excess stream power diagram from the meta‐analysis of Hassan & Bradley (2017) was updated with additional event‐based surveys from our data compilation (Figure 7a).…”

“…Stream power scaling laws from data compilation of bedload tracing surveys: (a) updating of the scatterplot from Hassan and Bradley (2017) between the mean distance of transport and the excess unit stream power, including tracing datasets collected in step‐pool (Gintz et al, 1996; Lamarre & Roy, 2008b; Lenzi, 2004; Rainato et al, 2020; Schneider et al, 2014), plane‐bed (Gilet et al, 2020; Houbrechts et al, 2015) and riffle pool channels (Arnaud et al, 2017; Haschenburger & Church, 1998; Houbrechts et al, 2015; Liébault et al, 2012; Papangelakis, McVicar, et al, 2019; Peeters et al, 2021; Plumb et al, 2017; Sear, 1996). Arid gravel‐bed rivers and gravel‐over sands correspond to data reported in Hassan et al (1992).…”

“…A better collapsing should be possible by considering the full hydrological forcing during periods between tracer surveys, as proposed by Phillips et al (2013), who introduced the concept of the dimensionless impulse for analysing tracer datasets. This approach was already successfully tested on several RFID tracer plumes (Arnaud et al, 2017; Chardon et al, 2021; Gilet et al, 2020; Imhoff & Wilcox, 2016; McQueen et al, 2021; Olinde & Johnson, 2015; Peeters et al, 2021; Plumb et al, 2017; Schneider et al, 2014), and a meta‐analysis of those data would be certainly very instructive. Hydrological time series must be shared for making this possible, which is currently not the case for most of reported tracer surveys.…”

Hydro-Sedimentary Monitoring of Beaver Dams Removal and Impact on Freshwater Mussels Habitats

“…De la sorte, l'utilisation des sticks hypoxies permet d'évaluer le degré de colmatage du lit caillouteux et de quantifier jusqu'à quelle profondeur s'exerce ce colmatage. Cette méthode a notamment été mise en oeuvre pour évaluer la qualité de frayères reconstituées pour poissons lithophiles (Peeters et al, 2021). L'essence de bois utilisée dans cette étude est le pin sylvestre (Pinus sylvestris).…”

Modelling Coarse-Sediment Propagation Following Gravel Augmentation: The Case of the Rhône River at Péage-De-Roussillon (France)

“…In this regard, particle tracking has probably been the most popular strategy for the field study of fluvial gravel displacement (and dispersion) along river channels (Hassan and Roy, 2016), and much research effort has been invested in tracking particle displacements in gravel-bed rivers using tagged stones. Such tracer research has helped to disentangle the nature of the multiple controls behind gravel transport (Hassan and Bradley, 2017;Vázquez-Tarrío et al, 2019a, 2019bMcQueen et al, 2021), which include the magnitude and duration of discharge (Phillips and Jerolmack, 2014;Houbrechts et al, 2015;Papangelakis et al, 2022), channel morphology (Pyrce and Ashmore, 2003;McQueen et al, 2021;Peeters et al, 2021), macro-bedforms (Vázquez-Tarrío et al, 2019b), grain-size (Church and Hassan, 1992), active-layer fluctuations (Haschenburger, 1999;, and the length scale of the channel (Beechie, 2001;Vázquez-Tarrío and Batalla, 2019). All this previous work has undoubtedly contributed to providing us with a clearer idea on how bedload behaves and how the controls on gravel displacements observed in the field largely depend on the scale of the study (Vázquez-Tarrío and Batalla, 2019).…”
