Year: 2021
Type: article
Abstract: In this paper, the occurrence of the area-wide droughts during the years 2011 to 2020 in Slovakia is assessed on the data from 164 water gauging station displayed online on the drought monitoring webpage of Slovak Hydrometeorological Institute and further analysed on 43 selected water-gauging stations.The mean monthly discharges are compared with the long-term mean monthly discharges for the reference period 1961-2000.Trend detection analysis of the mean monthly discharges in period 1961-2020 was concluded by Mann-Kendall trend test.The months of April, June, July, August and October were detected as the months with the highest occurrence of mean monthly discharges below 40% longterm mean monthly discharges for the reference period.The trend analysis of the mean monthly discharges confirmed significant decreasing trend in April, May, June, July and August.These results reinforce the need of continuous monitoring of the mean monthly discharges.Results of the monitoring available online in form of simple graphical output can present a tool for the timely detection of the incoming long-term drought periods with possibility of implementation of appropriate measures.
