Abstract
This paper experimentally analyzes the collapse of conical granular columns made out of non-cohesive granular materials. Dimensionless run-out lengths were found, as a function of the aspect ratio a, similar to those occurring in the collapse of cylindrical columns, although in the case of conical columns of high aspect ration, at the end of the collapse, a layer of grains that rotates around the cone axis appears and it affects the final profiles of the mounds.

This paper experimentally analyzes the collapse of conical granular columns made out of non-cohesive granular materials
We found that the normalized up conditions, experimentally obtained the scaled runout runout lengths, for the conical columns, obey power-laws length similar to those occurring in cylindrical columns
