ABSTRACT:
The main aim of the study was to assess drought risk in the Kopel river basin on the basis of analysis of observations made in the period from 1972 to 2011. The Kopel river is a right tributary of the Warta river which it joins at 254+600 km. The drought risk was assessed on the basis of meteorological and hydrological diurnal data. The trend analysis revealed that temperature has a significant increasing tendency. On the basis of SNQ and Q70% flows the indices such as drought duration and drought volume were computed. Statistical analysis showed negative correlations between drought indices and precipitation. The results presented in this study indicated that drought risk in the Kopel river basin is high.
