Analysis of the extreme water phenomenon (hydrological drought) in the small river basins in NE Romania

This paper presents an analysis of one of the climatic dangers experienced in recent times is the high intensity of the drought phenomenon on small rivers in NE Romania that affects society and ecosystems. As a case study, it is intended to identify statistically significant trends in the minimum flow characteristics of the Trebes Negel representative basin.This basin is located in the excessive continental temperate climate of the area, which is characterized by annual rainfall of only 500-600 mm. The parameters studied for this hydrological basin are a reference point for all small basins in Romania, located in the same natural environment and used in research. As a reference year, the year 2015 is analyzed, the project is registered in the Trebes Negel basin in September and October on the tributary of the Trebes river (Negel river, at the Magura hydrometric station) for 36 consecutive days.
