The variability of the water regime is ascertained as being influenced by the frequent natural evolutions in the span of decades and also by some abrupt changes in the recent periods, including the damages or grows of vegetation cover or human influence in the historical decades. Analysis of such natural or man-made impacts in the context of historical evolution could clarify uncertainties and oscillations in basin water regime. The events as changes in vegetation cover, resp. evapotranspiration, land-use changes, building of new reservoirs and disappearing the old ones, effect of water management changing the condition of the water supply should be evaluated taking into account the influencing of the natural water regime. The modeling of rainfall-runoff process could be used to identify such impacts, especially for the cases when the long term complex monitoring is missing. The difference between observed and simulated streams flow appears as the helpful tool for the assessments of the resulting water regime.
