title: Periodicity of Climatic, Hydrological and Lacustrine Sedimentation Processes in the South of the East-European Plain
abstract: Based on a Fourier analysis of a continuous series of observations (188 years) of the water discharge of the Dnieper River, the study has identified qualitatively distinct periods of the discharge formation and a cyclicity constituent of 12.5 years. By means of the piece regression models, which make it possible to define the contribution of annual sums of precipitation and air temperature to the riverine discharge, the study has established the climatic dependence of the hydrological processes.
