(groundwater regime, catchment area, real evapotranspiration, dynamic volume, water budget, Belo Vrelo, Serbia)
hydrogeological and climate conditions.A catchment area is deemed to be gauged if the regime of relevant quantitative parameters has been monitored for at least 30 years. A catchment area is partially gauged if monitoring lastedinto a discharge hydrograph. It isalso possible to determine dynamic groundwater volumes in a karst spring catchment area, the water budgetequation parameters and the like. It should be noted that a sufficiently long data set
and dolomites ofČemerno Mountain, was selected for the present case study. Key words: groundwater regime, catchment area, real evapotranspiration, dynamic volume, water budget,Belo Vrelo, Serbia.Апстракт: Довољно дуг низ осматрања
