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 …

Field techniques for measuring bedrock erosion and denudation

JM Turowski, KL Cook - Earth surface processes and landforms, 2017 - Wiley Online Library
Bedrock erosion rates in natural landscapes are usually slow, of the order of millimeters per
year or less, and sophisticated techniques have been developed to measure them. Different …

Measuring bed load transport rates by grain-size fraction using the Swiss plate geophone signal at the Erlenbach

CR Wyss, D Rickenmann, B Fritschi… - Journal of Hydraulic …, 2016 - ascelibrary.org
The Swiss plate geophone system is a bed load surrogate monitoring technique that is used
to quantify bed load transport in steep streams. The amplitude of the signal recorded by the …

Bed load sediment transport inferred from seismic signals near a river

DL Roth, EE Brodsky, NJ Finnegan… - Journal of …, 2016 - Wiley Online Library
Abstract We examine broadband (5–480 Hz) seismic data from the Erlenbach stream in the
Swiss Prealps, where discharge, precipitation, and bed load transport are independently …

Spatial patterns of erosion in a bedrock gorge

AR Beer, JM Turowski… - Journal of Geophysical …, 2017 - Wiley Online Library
Understanding the physical processes driving bedrock channel formation is essential for
interpreting and predicting the evolution of mountain landscapes. Here we analyze bedrock …

Effect of sediment supply on cyclic fluctuations of the disequilibrium ratio and threshold transport discharge, inferred from bedload transport measurements over 27 …

D Rickenmann - Water Resources Research, 2020 - Wiley Online Library
Bedload transport in natural channels typically shows large fluctuations even for constant
hydraulic forcing. It has been shown that the threshold shear stress for initiation of motion …

Testing models of step formation against observations of channel steps in a steep mountain stream

A Golly, JM Turowski, A Badoux… - Earth Surface Processes …, 2019 - Wiley Online Library
Steep streams often feature a step‐pool morphology where the steps determine channel
stability and dissipate the stream's energy, and thus are important for local flow hydraulics …

Bed load transport and boundary roughness changes as competing causes of hysteresis in the relationship between river discharge and seismic amplitude recorded …

DL Roth, NJ Finnegan, EE Brodsky… - Journal of …, 2017 - Wiley Online Library
Hysteresis in the relationship between bed load transport and river stage is a well‐
documented phenomenon with multiple known causes. Consequently, numerous studies …

Grain size effects on energy delivery to the streambed and links to bedrock erosion

JM Turowski, CR Wyss, AR Beer - Geophysical Research …, 2015 - Wiley Online Library
Fluvial bedrock erosion rates are thought to be proportional to the energy delivered to the
channel bed by impacting bed load particles. Combining methods for field measurements of …
