Angle of repose of snow: An experimental study on cohesive properties [PDF]

open access: yesCold Regions Science and Technology, 2022
The angle of repose is a measure reflecting the internal friction and cohesion properties of a granular material. In this paper, we present an experimental setup and measurements for the angle of repose of snow for seven different snow samples over a ...

Relaxation at the Angle of Repose

Physical Review Letters, 1989
We have investigated the distribution of avalanches which occur when the slope of a sandpile exceeds the metastable slope given by the angle of repose. In contradiction to recent models by Bak, Tang, and Wiesenfeld for the dynamics of granular systems, we do not observe power-law distributions. We also find that the slope of a sandpile decays as $log(t)

Angles of repose that exceed modern angles

Geology, 1990
Angles of repose for naturally occurring materials are known to be a function of, among other geologic parameters, the acceleration of gravity and cohesion between particles. Thus, steeper angles may have been recorded in ancient sediments because Earth9s acceleration of gravity was less than now.
