Abstract When wet soil becomes fully saturated by intense rainfall, or is shaken by an earthquake, it may fluidize catastrophically. Sand-rich slurries are treated as granular suspensions, where the failure is related to an unjamming transition, and

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 to result from transport-induced abrasion; however many researchers a

Millions of barrels of oil escaped into the Gulf of Mexico (GoM) after the 20 April, 2010 explosion of Deepwater Horizon (DH). Ocean circulation models were used to forecast oil slick migration in the GoM, however such models do not explicitly treat

Abstract Soils around the planet creep, despite wide variations in particle properties and environments. This sub‐yield “flow” of soil interacts with a variety of boundaries, in terms of geometry and friction. Here we explore the veracity of re

Earth’s largest dune fields are set to become less dynamic on average over this century due to anthropogenic climate change, with no future action able to mitigate this effect, as predicted by the newest iteration of CMIP models.

The downhill motion of soils on hillslopes is not well understood. Here, the authors present laboratory experiments and show that hillslopes are made perpetually fragile by environmental perturbations that prevent them from stabilizing.

Abstract How do scientists generate and weight candidate queries for hypothesis testing, and how does learning from observations or experimental data impact query selection? Field sciences offer a compelling context to ask these questions because que

The critical fluid-shear stress for the onset of sediment transport, θ_{c}, varies with the history of applied shear. This effect has been primarily attributed to compaction; the role of shear jamming is less explored. We examine the response of a g

River beds often exhibit armouring, in which formation of a coarse surface layer shields the finer underlying grains from erosion. Here, using experiments in a laboratory river and discrete and continuum models, the authors demonstrate that river-bed
