The change analysis of the mean monthly discharges in Slovakia in recent decades

Rok, strany: 2019, 10 - 21

An analysis of a hydrometeorological time data series is an important part in assessing changes in hydrological processes. Understanding changes in time series results in a better understanding of the causes of these changes. A time data series can be evaluated by a large number of analyses. One of them is the application of statistical methods. The article deals with a basic analysis of the mean monthly, annual, and seasonal discharges in selected stage-discharge gauging stations in Slovakia using statistical methods. The time data series were subjected to basic descriptive statistic, trend and periodicity analyses, and AR-ARCH model. These methods were applied to five larger basins in Slovakia and seven smaller basins located in the northern part of the Váh River basin. The results show greatest changes (in trend and periodic analysis) in the Hron River. From the smaller river basins, especially Kysuca and Bystrica River, there are statistically significant decreasing trend
