Long-term trend changes of monthly and extreme discharges for different time periods

Year, pages: 2019, 122 - 130

Nowadays, we are more frequently faced to the information about the extremes in discharge regime (floods and droughts) and their catastrophic consequences. Because of this, the first aim of hydrologists should be to verify these hypotheses and identify sources of mentioned changes. Rating extreme discharges is very important for example for assessing the impact of air temperature on the discharge. The upper parts of river basins are suitable for studying the effect of potential climate change or increased air temperature on drainage conditions in the basin. Analysis of trends in minimum discharges can predict its development and minimize its negative impacts on society and the environment. The contribution deals with the analysis of monthly discharges regime at gauging stations Bela-Podbanske (1929–2014) and Vah-Liptovsky Mikulas (1922–2014) and also analysis the minimum/maximum discharges in Bela River basin. Discharge analysed trends in mean monthly discharges and extreme discharges for selected time period to determine whether there is any significant change in the trend. We used the Mann-Kendall nonparametric test, which is one of the most widely used non-parametric tests to detect significant trends in time series.
