Abstract
The main goal of the research was a detailed study of the consequences, caused by groundwater abstraction in the Neresnica brook catchment (Slovak Republic) since the water supply source Podzamcok was put in operation in 1973. This goal was supplemented by research of groundwater origin, groundwater chemical composition and its changes. Field measurements, analyses of water samples and statistical evaluation of hydrometeorological data were used to gain and process the data. It was showed that overexploitation of groundwater in the catchment resulted in distinct diminishing of stream flow discharges in low flow periods, groundwater level dropping and disturbance of hydraulic connection between surface and groundwater. Groundwater quality was quite stable during the whole period of observation. Groundwater modeling was proposed to be used for the re-estimation of utilizable groundwater amounts in the catchment.
