Title: Hydrogeological and hydrodynamic characteristics of groundwater sources for the public water supply of Becej (Northern Serbia)
Abstract: The existing groundwater source for the public water supply of Becej City in Serbia is tapping groundwater from three water-bearing horizons over 15 wells with a summary capacity over 100 l/s. It is one of the characteristics of sources that several water-bearing layers are most frequently tapped simultaneously by wells. Two layers are tapped simultaneously by 12 wells; all three layers are tapped by ten wells, while one water-bearing layer is tapped by only three wells. The groundwater table at the source was recorded for a period of 30 years. In the conducted hydrodynamic analysis of the groundwater regime, it was concluded that in the mentioned period, a relatively low fall of the water table occurred, far lower than the previously predicted values. The results of a simulation of the exploitation regime of both the town and surrounding sources are presented in this paper for a period of more than two and a half years and the results of the identification of the basic hydrogeological parameters of the tapped water-bearing layers are presented in this paper. In addition, a balance for each element in the water-bearing layers exploited as sources of tapped water for the town are presented.
