ABSTRACT: Groundwater level regime was studied in the Zvolen basin between Banská Bystrica and Zvolen. Statistical evaluation and time series analyses were complemented by the study of interrelations among hydrological and climatic data. The study intended to confirm or reject the continuation of decreasing trends in hydrological variables which were detected within the climate change studies in the past. The results confirmed increasing trend of the air temperature values, almost stable precipitation amounts development and important decreasing trend of relative humidity during the period 1969 – 2006. Despite of this fact, groundwater levels in four of six assessed objects have an increasing trend – groundwater levels rising occur in the upper part of the assessed area. The reason could be in sufficient feeding of groundwater by precipitation and in permanently decreasing abstractions of groundwater in the upper part of the Hron River catchment. In one well located in the central part, no important changes were observed. Only for one well – located in the most southern part of the area, decreasing trend was documented. In this part, evapotranspiration plays probably an important role.
