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?
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
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
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
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
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 …
