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 …

Sediments have been found to be one of the most important reservoirs for microplastics,
providing abundant indigenous microbes. The processes involved in the distribution and …

Clinoforms are ubiquitous depositional surfaces in sedimentary systems. The quintessential
shape, with a flat or gentle topset, slo** foreset, and gentle to flat bottomset, is …

A prominent control on the flow over subaqueous dunes is the slope of the downstream
leeside. While previous work has focused on steep (~ 30°), asymmetric dunes with …

A new dataset of uniform and steady sheet-flow experiments is presented in this paper. An
acoustic concentration and velocity profiler (ACVP) is used to measure time-resolved …

Large‐scale wave flume experiments are conducted in the ripple vortex regime to study near
bed coarse sand transport processes below asymmetric surface waves typical of the coastal …

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 …

This paper presents novel insights into suspended sediment concentrations and fluxes
under a large-scale laboratory plunging wave. Measurements of sediment concentrations …

Flow transverse bedforms (ripples and dunes) are ubiquitous in rivers and coastal seas.
Local hydrodynamics and transport conditions depend on the size and geometry of these …

Underwater dunes are found in various environments with strong hydrodynamics and
movable sediment such as rivers, estuaries and continental shelves. They have a diversity of …
