Short summary
This paper studies the effect of slope gradient, rain intensity and soil particle size distribution on aggregate breakdown. Infiltration rate was found to increase under unsteady state conditions because of less development of surface seal. Under steady state conditions, no significant relationship was found between slope and infiltration rate.
