Erosion processes in the Altai

Abstract

Geomorphological regions, singled out within the limits of plains and mountains of the Altai Territory, differ from each other in structure, erosion network pattern, in density and bepth of dissection. The general direction of most forms in erosional system is predetermined by tectonics. In most regions NE direction of erosional landforms prevails which is controlled by mid- and late Quaternary faults or recent folds. The increase of minor erosional form instability and lateral channel erosion is traced from Kulunda Plain towards the Altai and Sal air foothills. The dynamics of erosion in the Altai Mountains depends directly on the land use of the territory.
