Abstract: Characteristics of alluvial water sources in the lower course of the Sava River, stratification ie. the cyclicity, granulometric and mineralogical-pelrological composition of the layers are the result of the formation conditions during Pleistocene, primarily climate change, namely the shift of several glacial and interglacial periods. In addition to the climatic condition that caused the cyclicity in terms of the diversity of the granulometric composition and the lithofacial characteristics of the layers, sedimentation conditions were predisposed by tectonic activity, which locally predisposed the possibility of sedimentation and the thickness of layers. The Belgrade water source is specific for several reasons. This is the largest source in the Sava River Basin in Serbia, the most downstream source, located at the very confluence of the Sava River and the Danube River, and the alluvial waters are exploited using 99 wells with horizontal drains and some vertical wells. Since the alluvial aquifer of Belgrade's groundwater source is characterized by great differences in terms of thickness and lithofacial characteristics of layers and filtration characteristics, as a consequence of complex genesis, the sustainable development and exploitation of the wells depend on the identification and analysis of the relevant ones for each of the wells individually. This paper presents an overview of local sedimentation conditions, from the aspect of tectonic conditions, on the profile Makiško polje - Donje Polje, based on three boreholes near the Rb-lm, Rb-6 (right bank) and Rb-36 wells (left bank).
