Learning the nature of viscoelasticity in geologic materials with MCMC
Ron Maor, Lars Hansen, Douglas Jerolmack +1
Rock and ice are ubiquitous geologic materials. While apparently solid, they also exhibit fluid behavior under stress - a property termed viscoelasticity. Viscoelastic convection o…
Decoding planetary surfaces by counting cracks
S. Silver, K. Regős, G. Domokos +1
Planets are often covered with thin cracked shells. From mud films to lithospheres of rock or ice, fracture networks form two-dimensional (2D) tessellations of convex polygons whos…
Strain hardening by sediment transport
Fernando David Cúñez Benalcázar, Erick de Moraes Franklin, Morgane Houssais +2
The critical fluid-shear stress for the onset of sediment transport, , varies with the history of applied shear. This effect has been attributed to compaction, but the role of…
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…
Circadian rhythm of dune-field activity
Andrew Gunn, Matt Wanker, Nicholas Lancaster +3
Wind-blown sand dunes are both a consequence and a driver of climate dynamics; they arise under persistently dry and windy conditions, and are sometimes a source for airborne dust.…
River-bed armoring as a granular segregation phenomenon
Behrooz Ferdowsi, Carlos P. Ortiz, Morgane Houssais +1
Gravel-river beds typically have an "armored" layer of coarse grains on the surface, which acts to protect finer particles underneath from erosion. River bed-load transport is a ki…
How river rocks round: resolving the shape-size paradox
G. Domokos, D. J. Jerolmack, A. Á. Sipos +1
River-bed sediments display two universal downstream trends: fining, in which particle size decreases; and rounding, where pebble shapes evolve toward ellipsoids. Rounding is known…
