Abstract—An important function in both engineering
hydrology and integrated catchment area management is
performed by statistical analysis. This paper presents the trend
analysis of low water flows in selected rivers in Eastern
Slovakia. There are many statistical methods for data
evaluation. The most of useful, presented in this paper, is
the non-parametric Mann-Kendall test. This analysis was
carried out for statistical data from 63 river stations lying in the
eastern part of Slovakia, namely in Hornád, Poprad, Bodva,
Bodrog river basins. The data were obtained from the Slovak
Hydrometeorological Institute, Regional Centre Košice.
Because the low flow data are not comparable for the individual
stations, normally it is only possible to do the statistical analysis
for each river station separately. The relative sizes of the low
stream flow trends in individual river stations were calculated
as directives of the trend lines. Using ArcView GIS was created
thematic map from geographical map of Eastern Slovakia and
was performed hydrological drought risk regionalization.
Index Terms—Hydrological drought, low flow, Mann-Kendall test, river station, trend analysis.
