Sculptural and alluvial landforms of incised channels in East Siberia: special features of the relief formation

Abstract

Configuration and distribution of sculptural and sculptural- alluvial formations in channels of East Siberian rivers are under control of geological-geomorphological factors, such as rock lithology and texture, tectonic structure, sediment delivery. Sculptural landforms - rock islands and stony ledges on the banks - are common for narrow valleys and places where rivers cut across tectonic structures. Sculptural-alluvial landforms are typical of the places where sediment input is abundant, such as tributary mouths and expanded sections of valleys.
