Abstract
In recent times, extremely dry seasons have been occurring more and more often in the eastern Slovakia, alternating with extremely wet seasons like torrential floods from extreme rainfall. Trend of reconnaissance drought index (RDI) and streamflow drought index (SDI) was evaluated in the paper using the Mann-Kendall test. The indices were evaluated at six climatic and river stations in the eastern Slovakia. The Mann-Kendal test results showed that the trend in the SDI index is not significant in 5 stations and only in one station the trend is significant. In the RDI index the trend is not significant in four stations and the trend is significant in two stationshe abstract is to indicate the subject of the paper, how the author proposes to develop the subject and its overall objective, aim or outcome.
