COMPARISON OF THE HYDROLOGICAL DROUGHT OF SURFACE WATERS IN 2022 WITH THE DROUGHT YEARS OF 1993, 2003 AND 2012
Abstract
The several-month rainfall deficit, which lasted mostly continuously from January to the beginning of September 2022, ranks 2022 among the hydrologically driest years in Slovenia. In terms of duration and severity, the surface water drought in 2022 can be compared to the droughts in 1993, 2003 and 2012. In all these years, the low water condition was present at the beginning of the year and lasted until autumn. The average monthly discharges of the analysed drought years were continuously below the long-term average from January to August. The driest months were March, July and August. Of the analysed drought years, 2003 was the driest year, followed by the droughts in 2022, 1993 and 2012. Drought is a regional phenomenon and never covers the entire country uniformly. In 2022, western and central Slovenia were more affected by the hydrological drought, while it was less pronounced in the east of the country.
