When extreme and non-extreme physical events, such as drought, can affect elements of human systems in an adverse manner, it assumes the characteristic of a hazard. Droughts are the most complex but least understood of all natural hazards. It is broadly defined as a “severe water shortage”. The objective of this paper was to investigate the number of days without precipitation during 30 years in chosen climatic stations in the eastern Slovakia. The results of the research proved that the occurrence of a drought in Slovakia is rare although periods longer than 30 days without precipitation were detected. This research may be helpful as one of the documents for water management practice, for example, for proposals of water harvesting in the country, the designing of other water structures or agricultural practices in the study area. The study of drought assessment is performed with the main goal of reducing negative impacts of droughts.
