A demonstration of the importance of bedload transport for fluvial bedrock erosion and knickpoint propagation

KL Cook, JM Turowski, N Hovius - Earth Surface Processes …, 2013 - Wiley Online Library
We provide field evidence for the role of bedload in driving fluvial incision and knickpoint
propagation. Using aerial photographs, field surveys, and hydrological data, we constrain …

Interaction among alluvial cover, bed roughness, and incision rate in purely bedrock and alluvial‐bedrock channel

T Inoue, N Izumi, Y Shimizu… - Journal of Geophysical …, 2014 - Wiley Online Library
A major control on bedrock incision is the interaction between alluvial cover and erosive
mobile grains. The extent of alluvial cover is typically predicted as a function of relative …

Alluvial cover controlling the width, slope and sinuosity of bedrock channels

JM Turowski - Earth Surface Dynamics, 2018 - esurf.copernicus.org
Bedrock channel slope and width are important parameters for setting bedload transport
capacity and for stream-profile inversion to obtain tectonics information. Channel width and …

Stochastic interpretation of the advection‐diffusion equation and its relevance to bed load transport

C Ancey, P Bohorquez… - Journal of Geophysical …, 2015 - Wiley Online Library
The advection‐diffusion equation is one of the most widespread equations in physics. It
arises quite often in the context of sediment transport, eg, for describing time and space …

A surface roughness model for predicting alluvial cover and bed load transport rate in bedrock channels

JPL Johnson - Journal of Geophysical Research: Earth Surface, 2014 - Wiley Online Library
Partial alluvial cover in bedrock channels influences downcutting rates and mountain river
morphodynamics. Flume experiments have demonstrated that a wide range of stable cover …

The SPACE 1.0 model: A Landlab component for 2-D calculation of sediment transport, bedrock erosion, and landscape evolution

CM Shobe, GE Tucker… - Geoscientific Model …, 2017 - gmd.copernicus.org
Models of landscape evolution by river erosion are often either transport-limited (sediment is
always available but may or may not be transportable) or detachment-limited (sediment must …

Mass balance, grade, and adjustment timescales in bedrock channels

JM Turowski - Earth Surface Dynamics, 2020 - esurf.copernicus.org
Rivers are dynamical systems that are thought to evolve towards a steady-state
configuration. Then, geomorphic parameters, such as channel width and slope, are constant …

Wide bedrock valley development and sensitivity to environmental perturbations: Insights from flume experiments in erodible bedrock

AL Langston, CH Robertson - Earth Surface Processes and …, 2023 - Wiley Online Library
Wide bedrock valleys and their genetic descendants, strath terraces, can serve as
morphological records of past climate that reflect river discharge and sediment load during …

Large floods, alluvial overprint, and bedrock erosion

JM Turowski, A Badoux, J Leuzinger… - Earth Surface …, 2013 - Wiley Online Library
Depending on their behaviour during extreme floods, streams can be divided into two
distinct classes, which derive from a simple threshold model of transport dynamics.'Flood …

Numerical simulation of effects of sediment supply on bedrock channel morphology

T Inoue, T Iwasaki, G Parker, Y Shimizu… - Journal of Hydraulic …, 2016 - ascelibrary.org
Natural bedrock rivers exhibit diverse erosional morphologies. Although the formation of
alternate bars on bedrock has been noted in previous studies, the influence of these …
