Abstract

This paper is concerned with some issues concerning the relationship of the sediment runoff, the degree of erosion dissection, and denudation intensity in the mountainous part of the Eastern Sayan region, as well as the characteristic features of excessive compensation of tectonic depressions by river sediment loads. An assessment is made of the consequences of such sedimentations in terms of plane deformations, the forking of river channels, the bogging up of adjacent areas, and disastrous floods.

Keywords: erosion, denudation, river sediment loads, sedimentation, tectonic depressions, runoff layer
