A plain region covering 8000 km2 in extreme north-eastern Romania which two groundwater levels are identified, near the surface (1.5 m) and in-depth (4.5 respectively. The statistical relationship between climate conditions underground water resources was assessed by means of correlation analysis autoregressive neural networks (ANNs). Based on this, study explores quantitative changes towards end this century according to most relevant scenarios regarding evolution air temperature precipitation amount. results ANNs model show that together with amount explain 50% 70% variability for 1983–2017 interval. For local instead, analysed at level main regional weather stations, explained decreases 40% 60%. This overall good performance enables us assimilate into data region. projections indicate decline is expected be general both analysed. Thus, impact change supply very high over region, adding onset effect diminishing quality, raising a great risk availability natural socio-economic environment.
