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 …

In rivers worldwide, multiple scales of dunes coexist. It is unknown how the larger, primary
dunes interact with secondary bedforms that are superimposed. We test the hypothesis that …

Characteristics of migrating bedforms are often used to indirectly quantify the volumetric
sediment flux in fluvial environments. Yet, the range of bedform scales that actually …

Multi‐scale bathymetries observed in laboratory channels and natural rivers have posed
several challenges to the description of bedform geometry and kinematics. To better quantify …

Abstract Study Region The coast of the Emilia-Romagna Region in northern Italy consists of
about 210 km of sandy beaches that have been attracting tourists for decades. Since the …

Bedforms emerge in a variety of shapes and sizes when a granular erodible surface is
subject to a strong enough shear flow, as observed in topographic data from submarine …

River beds evolve as a result of a complex interaction between strongly nonlinear processes
such as near‐bed turbulence, particle‐particle interaction, and particle‐bed interaction. This …

Accurately determining sediment loads is necessary for managing river environments but is
difficult because multiple processes can lead to large discharge‐independent changes in …

Results of bathymetric surveys conducted to examine changes of sand dunes geometry in
the Vistula River mouth before, during and after the extreme flood event are presented. A …

Bedforms are complex and varied features on riverbeds created by the interaction between
flow and sediment particles. Bedform evolution is crucial for understanding sediment …
