Modeling the dynamics of soil erosion and size-selective sediment transport over nonuniform topography in flume-scale experiments [PDF]

, 2011
Soil erosion and the associated nutrient fluxes can lead to severe degradation of surface waters. Given that both sediment transport and nutrient sorption are size selective, it is important to predict the particle size distribution (PSD) as well as the ...

Grain Size Sorting and Steady Bars Formation in Straight Channels—Part 1: Laboratory Experiments

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Surface grain size in gravel‐bed rivers is inherently heterogeneous, with marked spatial variability that remains challenging to predict, even in the presence of regular bedforms. This study investigates surface grain size variability on self‐formed alternate bars at the scale of a single bar unit, and is divided in two parts.

Height and wavelength of alternate bars in rivers: modelling vs. laboratory experiments [PDF]

, 2001
Alternate bars are large wave patterns in sandy beds of rivers and channels. The crests and troughs alternate between the banks of the channel. These bars, which move downstream several meters per day, reduce the navigability of the river.

Grain Size Sorting and Steady Bars Formation in Straight Channels—Part 2: Linear Theory

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract This is the second of two papers aimed to investigate grain sorting patterns associated with the formation of steady alternate bars in gravel‐bed rivers. Part 1 presented the analysis of a series of tailored experiments, performed in a mobile bed laboratory flume with fixed, straight banks. The results showed that a consistent pattern of grain

Deciphering Landslide Behavior Using Large-scale Flume Experiments

, 2008
Landslides can be triggered by a variety of hydrologic events and they can exhibit a wide range of movement dynamics. Effective prediction requires understanding these diverse behaviors.

Evolution of Soil Surface Roughness and Its Influence on Flow Pathways and Sediment Connectivity

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Soil surface roughness (RR) and its spatiotemporal variations are important for understanding soil erosion process, but how the erosion‐induced evolution of RR affects flow pathways and sediment connectivity patterns remains unclear. This study used high‐resolution topographic data sets from a long‐term rainfall simulation experiment in semi ...
