Abstract
The determination of spatial distribution of drought attributes in Isfahan province is essential for the study and management of drought. In this study, using ten drought attributes based on severity, duration and frequency of standardized precipitation index in 45 stations in Isfahan province and cluster analysis of this attributes, 5 spatial groups were identified in Isfahan province. The spatial distribution of these groups shows that the change in severity and duration of drought is based on various longitudes and latitudes in Isfahan province.
