Barchan dunes on Pluto?

EPJ Web of Conferences, 2017
We show that the orientation and morphology of bedforms occurring on top of Pluto’s smooth ice coats are consistent with an aeolian origin under conditions of unidirectional flow.

Modelling Bedforms on the Continental Shelf

, 2016
A number of morphodynamic models have been developed to simulate the dynamics of large-scale bedform patterns on the continental shelf. Most of the models are based on linear stability analysis and, therefore, only describe the characteristics of the bedforms at their formation.

Evidence of Secondary Bedform Controls on River Dune Migration

Geophysical Research Letters
In rivers worldwide, multiple scales of dunes coexist. It is unknown how the larger, primary dunes interact with secondary bedforms that are superimposed.

Studies in Aeolian geology [PDF]

The objective of the research was to assess the significance of aeolian (windblown) processes in the evolution of planetary surfaces. The approach was to use wind tunnel simulations, field studies of possible analogs, and analyses of spacecraft ...

Machine learning approaches for adequate prediction of flow resistance in alluvial channels with bedforms

Water Science and Technology
In natural rivers, flow conditions are mainly dependent on flow resistance and type of roughness. The interactions among flow and bedforms are complex in nature as bedform dynamics primarily regulate the flow resistance.

Giant ripples on comet 67P/Churyumov-Gerasimenko sculpted by sunset thermal wind

, 2017
Explaining the unexpected presence of dune-like patterns at the surface of the comet 67P/Churyumov-Gerasimenko requires conceptual and quantitative advances in the understanding of surface and outgassing processes. We show here that vapor flow emitted by

Stochastics of bedform dimensions

, 2006
Often river dunes are considered as regular bed patterns, with a mean dune height and a mean dune length. In reality however, river dunes are threedimensional and irregular features that cannot be fully described by their mean values. In fact, dune dimensions can be considered as stochastic variables. Their probability distribution can be characterized

Bedforms Feeding and Bedforms Fed by Canyon Activity Around Punta Alice Promontory (Calabria Ionian Margin, Italy)

, 2016
Submarine canyons along the Ionian Calabria margin indent large shelf sectors as the coalescing of smaller failure scarps progresses under the control of tectonic deformation and high sedimentation rates, promoted by regional uplift and rejuvenation of the drainage basin. The Punta Alice Canyon and the Ciro Canyon show such complex canyon heads, almost
