This paper outlines the various approaches used to calculate bedload transport. As bedload
transport exhibits considerable spatial and temporal variations, computing the bedload …

The dunes that cover the beds of most alluvial channels change in size and shape over time
and in space, which in turn affects the flow and sediment-transport dynamics of the river …

The delta of the Mekong River in Vietnam has been heavily impacted by anthropogenic
stresses in recent years, such as upstream dam construction and sand mining within the …

Sediment fluxes in aquatic environments are crucially dependent on bedform dynamics.
However, sediment-flux predictions rely almost completely on clean-sand studies, despite …

Dunes form critical agents of bedload transport in all of the world's big rivers, and constitute
appreciable sources of bed roughness and flow resistance. Dunes also generate …

River dunes are wavelike features in sandy riverbeds that move slowly in a downstream
direction. These bedforms are shaped by the interaction between flowing water and sand …

Field and laboratory studies indicate that changes in riverbed morphology often lag changes
in water discharge. This lagged response produces hysteresis in the relationship between …

Dunes dominate the bed of sand rivers and are of central importance in predicting flow
roughness and water levels. The present study has focused on the details of flow and …

Trains of secondary bedforms, superimposed on primary dunes, have been observed in
rivers worldwide. To date, it has remained unclear how these secondary bedforms affect the …

Dunes are important for bedload transport in almost all large river systems and exert an
important control flow resistance. Investigating dunes is fundamental for simulating …
