If a small amount of water is able to bridge the gaps between particles, electrostatic attraction of the water to mineral surfaces will increase soil strength. Physically, the angle of repose can be deﬁned as the. There is a minimum angle or maximum slope the sand will maintain due to the forces of gravity and.

Angle of repose is generally very close to angle of internal friction.

For soft angular particles (rock salt perhaps), repose could be a few degrees higher than what phi for the soil at the base of the retaining wall footing was used in determining the summation of resistance against sliding, and was unrelated. Angle of repose is depended on the density, surface area, and the shapes of the particle also the coefficient of friction. Angle of repose is a term used in science and engineering and can have two related meanings. It is one of the primary properties of powders that indicates the interparticulate friction and has been used to characterize the flow behavior of powders and granular materials with respect.
