Prut River basin is located in the south-eastern Europe, in a temperate climate of transition with significant variations of the precipitation regime. This study proposes a spatial and temporal analysis of drought in northeastern Romania, in the area drained by Prut River and its tributaries, between hydrological sections Oroftiana and Gorban, to emphasize its impact on a region where water resources need to be managed efficiently. Excessively dry months, with a frequency over 20% and excessively rainy ones placed between 18.08% and 21.69, lead to the frequent occurrence of drought. According to Topor aridity index a 67.60% frequency was obtained and most of the years have proven to be moderatedry. Between 1997 and 2013 the multiannual average values and the number of the extreme months have grown. The territorial variation of their weight, proved an increased torrentiality in the region delimited by the Botosani, Stefanesti-Stanca and Cotnari sections. UNESCO aridity index between 0.6 and 0.8 claim that this region is the second in terms of aridness intensity from Romania even if they belong to the wet class. Water has been a major limiting factor in the region as a result of the steadily decreasing amount due to the pollution and its insufficient reserves according to the riparian communities’ requirements.
