Journal ArticleDOI
The slumping of a cohesive granular column: Continuum and discrete modeling
TL;DR: In this article, the collapse of a cohesive granular column is investigated and the authors adopt a numerical approach and implement a peculiar rheology in a Navier-Stokes solver (Basilisk).
Journal ArticleDOI
Nondestructive Prediction of the Buckling Load of Imperfect Shells.

TL;DR: This study introduces a nonlinear description where finite-amplitude perturbations trigger buckling and provides a new promising framework to understand shell buckling, and more generally, imperfection-sensitive instabilities.
Journal ArticleDOI
Boltzmann Distribution of Sediment Transport.
TL;DR: This work tracks particles in a laboratory flume to relate their statistical behavior to the self-organization of the granular bed they make up, and finds that as they travel downstream, the transported grains wander randomly across the bed's surface, thus inducing cross-stream diffusion.
Journal ArticleDOI
Streamwise streaks induced by bedload diffusion
TL;DR: In this paper, the authors perturb a sediment bed with sinusoidal streaks, the crests of which are aligned with the flow, and find that when their wavelength is much larger than the flow depth, bedload diffusion brings mobile grains from troughs, where they are more numerous, to crests.
Journal ArticleDOI
Laboratory rivers adjust their shape to sediment transport.
TL;DR: It is shown that, at equilibrium, the river shapes its channel so that the intensity of sediment transport follows a Boltzmann distribution, which selects a well-defined width over which the river transports sediment, while the sediment remains virtually idle on its banks.
