Modeling the dynamics of aeolian meter-scale bedforms induced by bed heterogeneities
C. Rambert, J. M. Nield, C. Narteau +6
Desert surfaces are typically non uniform, with individual sand dunes generally surrounded by gravel or non-erodible beds. Similarly, beaches vary in composition and moisture that…
From lab to landscape-scale experiments for the morphodynamics of sand dunes
P. Claudin, S. Courrech du Pont, C. Narteau
We review the main processes that drive the morphodynamics of dunes, i.e. their growth in height, migration and elongation, and emphasise the contribution of experiments to the und…
Local Wind Regime Induced by Giant Linear Dunes: Comparison of ERA5-Land Reanalysis with Surface Measurements
Cyril Gadal, Pauline Delorme, Clément Narteau +4
Emergence and growth of sand dunes results from the dynamic interaction between topography, wind flow and sediment transport. While feedbacks between these variables are well studi…
Coexistence of two dune growth mechanisms in a landscape-scale experiment
Ping Lü, Clément Narteau, Zhibao Dong +5
In landscape-scale experiments at the edge of the Gobi desert, we show that various dune types develop simultaneously under natural wind conditions. Using 4 years of high-resolutio…
Direct validation of dune instability theory
Ping Lü, Clément Narteau, Zhibao Dong +6
Modern dune fields are valuable sources of information for the large-scale analysis of terrestrial and planetary environments and atmospheres, but their study relies on understandi…
Spatial and temporal development of incipient dunes
Cyril Gadal, Clément Narteau, Ryan C. Ewing +4
In zones of loose sand, wind-blown sand dunes emerge due the linear instability of a flat sedimentary bed. This instability has been studied in experiments and numerical models but…
Elongation and stability of a linear dune
O. Rozier, C. Narteau, C. Gadal +2
Compared to barchan dunes, the morphodynamics of linear dunes that elongate on a non-erodible bed is barely investigated by means of laboratory experiments or numerical simulations…
Periodicity in fields of elongating dunes
Cyril Gadal, Clément Narteau, Sylvain Courrech du Pont +2
Dune fields are commonly associated with periodic patterns that are among the most recognizable landscapes on Earth and other planetary bodies. However, in zones of limited sedimen…
Incipient bedforms in a bidirectional wind regime
Cyril Gadal, Clément Narteau, Sylvain Courrech du Pont +2
Most terrestrial sand seas form at `horse' latitudes, where the wind direction exhibits seasonal variation. Here, we extend the two-dimensional linear stability analysis of a flat…
Texture and composition of Titan's equatorial sand seas inferred from Cassini SAR data: Implications for aeolian transport and dune morphodynamics
Antoine Lucas, Sébastien Rodriguez, Florentin Lemonnier +5
The texture, composition, and morphology of dunes observed in the equatorial regions of Titan may reflect present and/or past climatic conditions. Determining the physio-chemical p…
Methane storms as a driver of Titan's dune orientation
Benjamin Charnay, Erika Barth, Scot Rafkin +5
Titan's equatorial regions are covered by eastward propagating linear dunes. This direction is opposite to mean surface winds simulated by Global Climate Models (GCMs), which are o…
Common dependence on stress for the statistics of granular avalanches and earthquakes
Takahiro Hatano, Clément Narteau, Peter Shebalin
The statistical properties of avalanches in a dissipative particulate system under slow shear are investigated using molecular dynamics simulations. It is found that the magnitude-…
