Abstract

Drought and aridity assessments have become issues of global importance as temperatures increase, precipitation amounts fluctuate, and socio-economic demands rise. Southern Romania and northern Bulgaria are the most intensively agriculturally used regions in both countries. Thus, widely-used aridity indices have been applied to the combined area, which generally highlighted a similar territorial pattern. The areas most affected by aridity include the Danube Delta, the Black Sea shore, and part of the Danube Alluvial Plain (according to the De Martonne Aridity Index, Gaussen correlation, and Selyaninov's hydrothermal coefficient). The Pearson correlation coefficient highlighted significant statistical correlations among the applied indices, except for the Pinna Combinative Index, which had correlation values between 0.69 (Ip/IE) and 0.74 (Ip/HTC).
