Hypsometric position and yield of aquifers under pressure in Danube region of Smederevo
Abstract
In this study, we have analyzed the characteristics of deep aquifers that belong to hydrogeological area of Morava region, that is a part of Smederevo Danube region. Hydrogeological complex of Smederevo Danube region was developed in the sediments originated in Neogene. We have observed alternative rotations of hydrogeological collectors, composed of sandy and gravel sediments and hydrogeological insulatorsthat make clay creations. Based on the analysis of geological research, geophysical exploration and drilling for the need of water supply, we have tried to present a spatial position of the collectors, and dense aquifers formed in them. Mapping the dispersion of collectors and evaluating the yield of deep aquifers, it is possible to ascertain the possible usage of water under pressure. Aquifer under pressure is of sub-artesian and artesian character with the level of groundwater from +0.6 to -90 m. Exploitation yield of objects ranges over 5 l/s. Chemical analysis of groundwater from Pontic water-bearing sands, according to Alekin, shows that it belongs to the hydrocarbon-alkaline earth types of water whose mineralization is around 0.5 g/l. This means that this water is moderately hard and that it can be used for drinking. The waters of Pannonian layers belong to soft water, and in the deeper parts there is a possibility of increased mineralization.
