DOI: 10.1002/esp.5243
Abstract: Large bedforms (dunes) are present in many shallow‐water environments. Knowledge of their dimensions and dynamics is required for river and coastal management. In tidal rivers and estuaries, the interaction among hydrodynamics (which results from the… read more here.

DOI: 10.1016/j.ijsrc.2017.05.003
Abstract: Abstract Non-uniform sediment deposited in a confined, steep mountain channel can alter the bed surface composition. This study evaluates the contribution of geometric and resistance parameters to bed stabilization and the reduction in sediment transport.… read more here.

DOI: 10.1029/2019gl085910
Abstract: Fluvial cross strata are an archive of ancient river morphodynamics. Controls on their preservation are well documented for bedforms equilibrated with prevailing flows; however, variability in water and sediment discharge results in bedforms that are… read more here.

DOI: 10.1029/2019jf005058
Abstract: Research on the morphodynamics of bedrock rivers has primarily focused on bedrock incision, and little is known about the alluvial morphodynamics of rivers with exposed bedrock surfaces. More specifically, there is a lack of information… read more here.

DOI: 10.1038/s41598-017-09065-9
Abstract: Small-scale (mm to m) sedimentary structures (e.g. ripple lamination, cross-bedding) have received a great deal of attention in sedimentary geology. The influence of depositional heterogeneity on subsurface fluid flow is now widely recognized, but incorporating… read more here.

Reconstruction of bedform dynamics controlled by supercritical flow in the channel–lobe transition zone of a deep‐water delta (Sant Llorenç del Munt, north‐east Spain, Eocene)

DOI: 10.1111/sed.12735
Abstract: Stable supercritical‐flow bedform phases under two‐dimensional steady flow are geometrically simple and include long‐wavelength cyclic steps at high Froude numbers and antidunes characterized by in‐phase flow that is near critical. Less well understood are the… read more here.
