In sand-bedded rivers, dunes dominate sediment transport and flow resistance. Dunes are
also commonly preserved in fluvial deposits as cross-stratified units that record their size …

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 …

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 …

Alluvial river channels are intrinsically mobile. We mapped channel planform extent in a
series of experiments to measure instantaneous rates of channel motion, loss of planform …

Riverbed elevations play a crucial role in sediment transport and flow resistance, making it
essential to understand and quantify their effects. This knowledge is vital for various fields …

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 …

Bed load transport and erosion in fine sediment beds are mainly driven by the dynamics of
the near‐bed turbulent flow. In situations when the shear stress is not sufficiently high to …

River dunes, dynamic bedforms in the river bed, limit navigable depths during low flows and
increase bed roughness. To predict the navigable depth or where maintenance dredging is …

Dune dimensions in sand‐bedded rivers are often thought to scale with flow depth (h), with
height (H) scaling as 1/6h and length (L) as 5h, even though substantial scatter about the …
