Bedload transport: a walk between randomness and determinism. Part 2. Challenges and prospects

C Ancey - Journal of Hydraulic Research, 2020 - Taylor & Francis
By the late nineteenth century, the scientific study of bedload transport had emerged as an
offshoot of hydraulics and geomorphology. Since then, computing bedload transport rates …

[HTML][HTML] Scaling behavior of bedload transport: what if Bagnold was right?

C Ancey, A Recking - Earth-Science Reviews, 2023 - Elsevier
There is a paradox in the relationship between bedload transport rates and flow variables:
laboratory and field studies have reported on how bedload transport rates depend on flow …

Assessment of XGBoost to estimate total sediment loads in rivers

R Piraei, SH Afzali, M Niazkar - Water Resources Management, 2023 - Springer
Estimation of total sediment loads is a significant topic in river management as direct
measurement is costly and time-consuming. This study aims not only to use the eXtreme …

Sediment supply controls equilibrium channel geometry in gravel rivers

AM Pfeiffer, NJ Finnegan… - Proceedings of the …, 2017 - National Acad Sciences
In many gravel-bedded rivers, floods that fill the channel banks create just enough shear
stress to move the median-sized gravel particles on the bed surface (D 50). Because this …

[HTML][HTML] Effects of sediment transport on flood hazards: Lessons learned and remaining challenges

D Vázquez-Tarrío, V Ruiz-Villanueva, J Garrote… - Geomorphology, 2024 - Elsevier
Sediment transport (bedload and suspension) plays a relevant role in the morphological
response of river channels to large floods. Sediment load controls erosion and aggradation …

Quantifying the morphological print of bedload transport

A Recking, G Piton, D Vazquez‐Tarrio… - Earth Surface …, 2016 - Wiley Online Library
Bedload and river morphology interact in a strong feedback manner. Bedload conditions the
development of river morphology along different space and time scales; however, by …

Channel response to sediment replenishment in a large gravel‐bed river: The case of the Saint‐Sauveur dam in the Buëch River (Southern Alps, France)

G Brousse, G Arnaud‐Fassetta… - River Research and …, 2020 - Wiley Online Library
Abstract The Saint‐Sauveur dam was built in 1992 in the middle section of the Buëch River.
Downstream of the dam, a channel incision by several meters was observed. A gravel …

An analysis of nonlinearity effects on bed load transport prediction

A Recking - Journal of Geophysical Research: Earth Surface, 2013 - Wiley Online Library
Because bed load equations are nonlinear and because parameters describing the flow and
the bed can have large variance, different results are expected when integrating bed load …

[HTML][HTML] Comparison of three grain size measuring methods applied to coarse-grained gravel deposits

P Garefalakis, AH do Prado, D Mair, GA Douillet… - Sedimentary …, 2023 - Elsevier
The size of grains in gravel and conglomerate deposits is most easily measured on photos
taken from related outcrops. However, the occlusion of grains by the sedimentary matrix or …

Estimating mean bedload transport rates and their uncertainty

C Ancey, I Pascal - Journal of Geophysical Research: Earth …, 2020 - Wiley Online Library
Measuring bedload transport rates usually involves measuring the flux of sediment or
collecting sediment during a certain interval of time Δ t. Because bedload transport rates …
