ABSTRACT. – Lack of rainfall in short time scales mainly affects soil moisture, whereas long-term rainfall deficit often affects streamflow and groundwater. The evolution of drought phenomena at all natural levels are analyzed selectively using different parameters. The evaluation of hydrogeological droughts was made for 7 hydrogeological wells developed on north-eastern part of Romania in the period between 1983 to 2018. Hydrogeological droughts were analyzed using groundwater level duration curve (GLDC) and extracting the corresponding groundwater levels of the 90-percentile (GL90). The results show that the climatic conditions from the year 2012 have a major impact of hydrogeological droughts for entire regions. Also was observed an increase of hydrogeological droughts intensity for the groundwater level situated near the surface (1-2 m) with effects on high variation of groundwater level and implications on management of water resources in the region.
