Groundwaters of the “Valjevo Karst” Area (Western Serbia)

Abstract

“Valjevo karst” is a merokarst area of about 320 km², in the Inner Dinarides of Western Serbia. In the litho-stratigraphic view, the karstified limestones of Middle-Upper Triassic dominate, in which karst aquifers are formed. Analysis and systematization of the available data of hydrogeological and other relevant research is carried out. A branched network of groundwater traces between swallow holes and discharge points is presented as well as main features of fourteen karst springs (or scattered discharge zones) and nine (group of) wells, divided into four sectors. The total minimum flow rate of the analyzed karst springs and discharge zones is estimated at 1.1 m³/s, while the total flow rate of the analyzed wells is estimated at about 0.3-0.4 m³/s, which makes about 1.5 m³/s totally. All analyzed waters are low-mineralized (<1 g/l), while temperatures ranged from 9-35^oС. Use of the water is multipurpose: municipal and local water supply, commercial bottling, recreational pools etc.
