Modern Alterations of Climate Characteristics and Probabilistic Assessment of the Minimal Flow Alterations in the Volga River Basin

Abstract

Unstationarity has been revealed in rows of minimal winter and summer/fall flow of the Volga basin and conventional stationary periods have been separated, the stationary regimes change dates have been determined. A method of obtaining of estimations of the minimal winter flow for future on the basis of correlation of minimal flow values changes with increments of ambient temperature to its average values over the previous conditionally stationary period.
