Slope erosion and aggradation

Abstract

Studies of zones of erosion, transport and aggradation in slope rills (micro-channels) and field experiments confirmed the possibility of deluvial slope apron formation at most part of slope under conditions of constant slope angle but decrease in water discharge downslope. Most important feature of the channel erosion on slopes (no matter what are the channel's parameters) is formation and movement of vertical scarps at the floor. The phenomenon should be taken into consideration when methods of slope wash estimation are worked out.
