Feb 08, 2017· It can also be used in determining whether or not a slope (of a stockpile, or uncompacted gravel bank, for example) will likely collapse; the talus slope is derived from angle of repose and represents the steepest slope a pile of granular material ,

It was found that the angle of repose (AoR), defined as the angle of inclination of the free surface to the horizontal of a bulk solid pile, was useful to characterize the flow behavior of powders and granular materials (Carr, 1965a,b; Zhou, Xu, Xu, & Zulli, 2002)
The height of a conical pile of grain is likewise dependent on the diameter of the pile and can be computed if the average filling angle (angle of repose) is known for the particular type of grain One useful result of this relationship is that the diameter of a conical pile of grain can be estimated if the number of bushels is known
