Abstract
The aim of this paper is to identify statistically significant trends in stream flow characteristics of low water content in the eastern
Slovakia, which are used in the evaluation of hydrological drought. Methodology for evaluating hydrological drought is based on
statistical analysis of observed minimal stream flows at river stations. This analysis was carried out for statistical data from 63 river
stations lying in the eastern part of Slovakia, namely in Hornad, Poprad, Bodva, Bodrog river basins. The data were obtained from the
Slovak Hydrometeorological Institute, Regional Centre Košice. Mann-Kendall statistical test identifies the frequency of minimal stream
flow trends. Obtained results from the statistically significant trends in the stream flows are basement for the regionalization of the eastern
Slovakia territory from the point of hydrological drought risk.
Keywords: hydrological drought; minimal stream flows; statistical tests; trend analysis.
