Main characteristics of water regime of the phreatic aquifer in Šid municipality (Vojvodina, Serbia)

Abstract

Šid municipality is situated in the south-western part of Autonomous Province of Vojvodina (northwestern Serbia). Four geomorphological units are represented on its territory: The Fruška Gora Mountain, Srem loess plateau, Srem loess terrace and alluvial plains of river Sava and its tributaries.The largest part of Šid municipality consists of the early Quaternary sediments of intergranular porosity which form the water collecting environment for the phreatic aquifer. Because of the incomplete database, the main goals of this paper are restricted on defining basic characteristics of water regime of the phreatic aquifer in Šid municipality and their causal connection with the climatic, hydrological and anthropogenic factors. The results showed the prevailing presence of climatic type of the phreatic aquifer water regime in the study area, with fragmentary presence of climatic-hydrological type near rivers and climatic-anthropogenic type near and inside the city of Šid. Special emphasis is given to the inadequate phreatic water table depth monitoring in the study area. This situation prevents the detailed study of the phreatic aquifer water regime and estimating the exact directions of its outputs, which creates a significant problem that needs to be solved in the near future.
