Using what has become a celebrated catchphrase, Philip W. Anderson once wrote that
“more is different”(Science, Vol. 177, Issue 4047, pp. 393–396, 1972). First formulated in the …

This article deals with the resuspension phenomenon whereby particles adhering on a wall
surface can be re-entrained by a flowing fluid. This is an area where significant progress has …

The entrainment of coarse sediment particles under the action of fluctuating hydrodynamic
forces is investigated from an energy perspective. It is demonstrated that the entrainment of …

The role of coherent airflow structures capable of setting gravel‐sized particles in motion is
studied theoretically and experimentally. Specifically, a micromechanical model based on …

The occurrence of sufficiently energetic flow events characterized by impulses of varying
magnitude is treated as a point process. It is hypothesized that the rare but extreme …

Bed load transport is a highly complex process. The probability density function (PDF) of
particle velocities results from the local particle momentum variability in response to fluid …

The overall objective of this study is to identify the physical mechanisms responsible for the
entrainment of an exposed particle subject to rapidly fluctuating hydrodynamic forces in the …

A few decades ago, river erosion protective approaches were widely implemented, such as
straightening the river course, enhancing riverbed/bank stability with layers of concrete or …

Erosion, transportation and deposition of sediments and pollutants influence the
hydrosphere, pedosphere, biosphere and atmosphere in profound ways. Even though the …

The use of a neuro‐fuzzy approach is proposed to model the dynamics of entrainment of a
coarse particle by rolling. It is hypothesized that near‐bed turbulent flow structures of …
