River Flow Alterations Caused by Intense Anthropogenic Uses and Future Climate Variability Implications in the Balkans

River flow alterations, caused by climate variability/change and intense anthropogenic uses (e.g., regulation dams) are considered among the main global challenges of which hydrologists should be dealing with. For purpose this study, environmental potential hydrological alterations made for extended Drin river basin, with limited historical information available. To overcome limitation assessment is using simulated streamflow data from a watershed model. Descriptive statistics applied to values indicate that median monthly flows no consistently greater than those 0–37.4 m3/s in all subbasins. Moreover, an investigation impact on regime simulations Results hydrologic alteration between nonregulated regulated conditions. More specifically, Global Circulation Models Regional Climate combinations, both unregulated conditions, minimum discharge had statistically significant decreasing trends, except one combination (RCP 4.5–RCA4/ECEARTH) Finally, results preliminary analysis could enhance necessary conversations relevant stakeholders discuss decide sustainable water resources management issues development Basin Management Plan future.
