Loose material thickness on slopes subjected to mass movement and dynamic state of the slopes

Abstract

Variations in the loose mantle thickness have been traced along 24 test pit profiles across convex and convex-concave slopes in the Lower Amur drainage basin. The analysis revealed that the loose mantle thickness on the slopes of mass movement depended on dynamic state of the slopes and not on their steepness. Most typical of the slopes in the region is the state close to erosional equilibrium, the state being achieved by the way of periodical changes in the direction of slope processes and deposits budget at the base of the slope.
