Short-period cycle of erosion-accumulation processes in the mountain river basin
Abstract
The mechanism of erosion-accumulation processes in the mountain river valley was studied. The data on precipitation, seismic activity, hydraulic regime as well as phototheodolite images of test sites during 27 years observations were used. Two phases were revealed in the valley development: accumulative and erosional. Together they constitute 26-27-year cycle. The latter corresponds to two II-year cycles of solar activity, thence atmospheric circulation appears to be the main factor of erosion changes.
