Formation of useful waters on the Stara Planina mountain, in the area Visok Kraj

Formation and discharge of useful waters was studied on southwestern slopes of the Stara Planina Mountain, in the area Visok Kraj that is the typical hilly-mountainous region in East Serbia. The catchment’s area of Dojkinacka River was chosen due to numerous and specific edaphic properties. Pump forests (association: Fagetum moesiacea serbicum Rud.) dominate here and were mostly developed on slightly acidic, humus-silicate or on acidic brownish soil. Soils are of a range of depths and development of pedogenetic processes. The aim of this work is to highlight elements that have pronounced influence on supply of useful and small water bodies in the catchment area of Dojkinacka River. Complex relations between geological setting, climate conditions, pedological characteristics, hydrological and hydrogeological conditions, forest vegetation etc. were analyzed. Elements that are significant for proper evaluation of useful water or small domains supply were in this case detected through water balance methods, geological mapping and tracking. It was deduced that the disagreement of topographic and hydrological catchment’s area of Dojkinacka River represents the significant element which should be taken into consideration in order to determine the real reserves of useful, i.e. small water domains.
