Abstract Riverbeds often fine downstream, with a gravel‐bedded reach, a relatively abrupt gravel‐sand transition (GST), and a sand‐bedded reach. Underlying this behavior, bed grain size distributions are often bimodal, with a relative paucity (

Study region: Twenty-six glaciated basins on the Interior Plateau (56° N, 125° W) in British Columbia, Canada. Study focus: Landscape and streamflow characteristics in glaciated basins show high spatiotemporal variability, while the linkages among

Structure-from-Motion (SfM) photogrammetry has become a popular solution for three-dimensional topographic data collection in geosciences and can be used for measuring submerged bed surfaces in shallow and clear water systems. However, the performanc

River capture acts as one river steals the neighboring headwaters, which is a dramatic natural process for mountain landscapes evolution. Here the authors show a stream piracy reversed flow in a major river resulting in waterfall formation, bedrock g

Growing interest in supraglacial channels, coupled with the increasing availability of high-resolution remotely sensed imagery of glacier surfaces, motivates the development and testing of new approaches to delineating surface meltwater channels. We

A potential control of downstream channel width variations on the structure and planform of pool–riffle sequence local bed topography is a key to the dynamics of gravel bed rivers. How established pool–riffle sequences respond to time-varying cha

We formulate the bedload sediment flux probability distribution from the Lagrangian dynamics of individual grains. Individual particles obey Langevin equations wherein the stochastic forces driving particle motions are switched on and off by particle
