Threshold constraints on the size, shape and stability of alluvial rivers

CB Phillips, CC Masteller, LJ Slater… - Nature Reviews Earth & …, 2022 - nature.com
The geometry of alluvial river channels both controls and adjusts to the flow of water and
sediment within them. This feedback between flow and form modulates flood risk, and the …

[图书][B] Rivers in the Landscape

E Wohl - 2020 - books.google.com
Rivers are the great shapers of terrestrial landscapes. Very few points on Earth above sea
level do not lie within a drainage basin. Even points distant from the nearest channel are …

The trouble with shear stress

EM Yager, JG Venditti, HJ Smith, MW Schmeeckle - Geomorphology, 2018 - Elsevier
Predicted bedload fluxes often have large errors partly because calculations usually do not
include spatial and temporal flow variability. Sediment motion is driven by a temporal …

History‐dependent threshold for motion revealed by continuous bedload transport measurements in a steep mountain stream

CC Masteller, NJ Finnegan, JM Turowski… - Geophysical …, 2019 - Wiley Online Library
To explore the causes of history‐dependent sediment transport in rivers, we use a 19‐year
record of coarse sediment transport from a steep channel in Switzerland. We observe a …

Impact of flow regulation on stream morphology and habitat quality distribution

J Duffin, EM Yager, JM Buffington, R Benjankar… - Science of the Total …, 2023 - Elsevier
The importance of interactions among stream hydrology, morphology, and biology is well
recognized in studies of stream ecosystems. However, when quantifying the impacts of …

Laboratory flume experiments with the S wiss plate geophone bed load monitoring system: 2. Application to field sites with direct bed load samples

CR Wyss, D Rickenmann, B Fritschi… - Water Resources …, 2016 - Wiley Online Library
The Swiss plate geophone is a bed load surrogate monitoring system that had been
calibrated in several gravel bed streams through field calibration measurements. Field …

Estimation of bed material transport in gravel‐bed streams using the virtual velocity approach: Insights from the North‐Western Himalayas, India

A Yadav, S Sen, L Mao… - Earth Surface Processes …, 2024 - Wiley Online Library
This study focuses on evaluating the sediment mobility and transport patterns in two
Himalayan rivers (Aglar and Paligad Rivers) during monsoon and non‐monsoon flows. The …

Bankfull transport capacity and the threshold of motion in coarse‐grained rivers

CB Phillips, DJ Jerolmack - Water Resources Research, 2019 - Wiley Online Library
The threshold stress for bed sediment transport exerts a primary control on the geometry and
stability of coarse‐grained rivers (diameter≥ 5 mm). Understanding how riverbed mobility …

Boulder array effects on bedload pulses and depositional patches

AN Papanicolaou, AG Tsakiris… - Journal of …, 2018 - Wiley Online Library
The influence of boulders in high gradient gravel‐bed rivers can be significant. Yet few
studies have isolated their role in regulating bedload. It is hypothesized that boulder relative …

Evaluating the effect of morphologic units on fractional sediment mobility and bedload transport in a small pool‐riffle reach

NG Al‐Ghorani, MA Hassan… - Water Resources …, 2024 - Wiley Online Library
This study examines the spatial pattern of fractional sediment mobility and assesses the
influence of morphologic units on bedload transport in a small pool‐riffle reach with limited …
