Angle of repose - Wikipedia

The angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping. At this angle, the material on the slope face is on the verge of sliding. The angle of repose can range from 0° to 90°.

MEASURING THE ANGLE OF REPOSE OF GRANULAR .

the following conclusions can be made: (a) the angle of repose of the granular systems was influenced by the degree of roughness of the base on which the grains came to rest. The rougher the base was, the higher was the angle of repose; (b) the mode of failure of the conical pile of grains was different depending if the base was rough or smooth.

Rock Sizing for Drainage Channels - Catchments and Creeks

Crushed rock is generally more stable than natural rounded stone. A 36% increase in rock size is recommended for rounded rock. The rock should be durable and resistant to weathering, and should be proportioned so that neither the breadth nor the thickness of a single rock is less than one-third its length.
