Abstract

The article considers the need to evaluate the homogeneity of hydrological series using several statistical criteria, since the effectiveness of methods for testing homogeneity depends on the distribution of data. In addition to the officially recommended statistical parametric Student and Fisher criteria for this purpose, the Buishand tests, the standard normal homogeneity test and the nonparametric Pettitt test were tested to assess the homogeneity of the time series of the runoff of rivers in Belarus. Based on the application of tests for series of different types of runoff, the classification of the studied series is carried out depending on the number of tests confirming the homogeneity hypothesis.
