Abstract

Summary

The probabilistic characteristics of the river ice regimes the significantly expand knowledge about its variability, magnitudes, duration and appearance timing of the main phases. Along with this, the probabilistic characteristics of the river ice regimes of Ukraine were calculated in the 70s of the 20th century, including for some rivers of the Prypiat basin. Probabilistic characteristics of the duration of ice phenomena on rivers were not determined at all. This research presents the results of determining probabilistic characteristics of the duration of ice phenomena on the rivers of the Pripyat basin within Ukraine based on the data of 29 water gauges for the period from the beginning of observations to 2020. As statistical parameters, such indicators as the multi-annual mean, coefficients of variation and asymmetry were used. These parameters were determined by the method of moments. The analytical distribution of the ice phenomena duration on the rivers were determined by the Pearson curve of type III, and the empirical distribution were determined by the Weibull formula. The obtained results show that the Pearson type III distribution quite well describes the empirical points of the ice phenomena duration on the rivers. Analytical distribution curves have a small negative asymmetry.
