The coupling of computational fluid dynamics (CFD) and discrete element method (DEM)
has become an important method for studying dense fluidized beds. Since DEM can track …

Predicting the morphodynamics of sedimentary landscapes due to fluvial and aeolian flows
requires answering the following questions: Is the flow strong enough to initiate sediment …

When deformed beyond their elastic limits, crystalline solids flow plastically via particle
rearrangements localized around structural defects. Disordered solids also flow, but without …

Debris flows are dense and fast-moving complex suspensions of soil and water that threaten
lives and infrastructure. Assessing the hazard potential of debris flows requires predicting …

Earth's surface is composed of a staggering diversity of particulate–fluid mixtures: dry to wet,
dilute to dense, colloidal to granular and attractive to repulsive particles. This material variety …

River bed-load transport is a kind of dense granular flow, and such flows are known to
segregate grains. While gravel-river beds typically have an “armoured” layer of coarse …

We develop a physical and computational model for performing fully coupled, grain-resolved
direct numerical simulations of cohesive sediment, based on the immersed boundary …

Purpose An innovative way to define navigable fluid mud layers is to make use of their
rheological properties, in particular their yield stress. In order to help the development of in …

Soil creeps imperceptibly but relentlessly downhill, sha** landscapes and the human and
ecological communities that live within them. What causes this granular material to 'flow'at …

Sediment transport simulations face the challenge of accounting for vastly different scales in
space and time that cannot be tackled by a unifying approach. Instead, processes are …
