This paper presents a morphodynamic model for free surface flows over bed forms. The
model reproduces bed form evolution and migration in a physically based manner. The flow …

Research into fluvial dunes spans disciplines, studies at grain to reach scales, and
methodological approaches that include theoretical, experimental, numerical and field …

We report an experimental investigation of the motion of bed load particles under steady and
spatially uniform turbulent flow above a flat sediment bed of uniform grain size. Using a high …

Hyporheic exchange has been hypothesized to have basin‐scale consequences; however,
predictions throughout river networks are limited by available geomorphic and …

The current understanding of the effects of turbulence on the swimming performance of fish
is primarily derived from laboratory experiments under pressurised flow swim tunnels and …

Authorities and planners involved in river restoration projects often tend to focus on the
hydromorphological state of a short river reach or certain aquatic habitats where the pending …

Transported driftwood and woody debris during floods may lead to accumulations and
blockages at river bridges or weirs, and can result in excessive scour or an increase in …

This paper gives an overview of the meaning of the term “roughness” in the field of fluvial
hydraulics, and how it is often formulated as a “resistance to flow” term in 1D, 2D and 3D …

The tropical Cerrado savannah, the second‐largest South American biome, is undergoing
the most rapid land‐use change in South America, including a wholesale shift from native …

The Shields diagram remains the most widely used criterion for incipient motion of sediment.
However its implicit nature makes applications rather inconvenient. By deploying Guo's …
