Detection of hydrological characteristics using statistical analysis in the upper basin of Desnatui River, Romania (1964 - 2011)

This study focuses on the graphical and mathematical representations of some important hydrological datasets (annual and monthly mean flow, flood hydrographs) available for Dragoia hydrometric station, situated in the south of the upper sector of Desnatui river basin, the biggest first order tributary of Danube river between Jiu river and Cerna river. The data entries were evaluated after the frequential hydrology principles, the temporal scenario revealed by the calcula being correlated to the geographical features of the river basin, especially the climatic regime and the particularities of flow. The results of this research proved useful for the watershed management, constituting a scientific way to demonstrate the scarce of the surface water resources in this area of Getic Plateau, along with the uncertainty which rises when we try to predict the flood effects during peak rainfalls or the etiage flow intervals.
