Experimental Study of the Angle of Repose of Coral Sands

Journal of Marine Science and Engineering
The angle of repose is a fundamental parameter for assessing the stability of coral reefs. However, predictive models for this angle are currently lacking.

Antlion sand interaction: A study of repose angle

Biogeotechnics
The antlions dig a conical simple pit in sand to catch ants. The funnel shape of the trap is deliberate with a critical angle of repose and is steep and shallow enough to trigger avalanches and cause struggling prey to fall into the funnel.

Angle of repose revisited: When is a heap a cone?

EPJ Web of Conferences, 2017
The angle of repose is a frequently reported value in bulk solids characterisation and its popularity is based on the simple measurement setup. It can be useful to estimate the flowability of a bulk material or to estimate the inner friction coeffcient ...

Angle of repose of granulated ice: effect of wood ash

Journal of Glaciology
New experiments have revealed that the addition of a small amount of wood ash doubles the angle of repose of granulated ice at −10°C, but has little effect at −30°C. It is hypothesized that this behavior may be explained in terms of the freezing of water
