Quantitative evaluation of the sheet wash processes on the slopes in the arid zone of Turgai Trough

Abstract

On the basis of many-year data, obtained in the study of sheet wash processes at key plot, situated in the arid zone, quantitative evaluation is given of the intensity of washing processes on the slopes of different exposition. It is shown that the intensity of sheet wash is controlled by physical-geographical peculiarities of the arid zone and geological-geomorphological features of the slop.es. It is revealed that a sheet wash process in space and time is of a complicated wave-like character - a temporal accumulation takes place during a washing process as well.
