Abstract

?Valjevo karst? is an area of about 780 km2 in a broader sense, while the uncovered karstified limestone makes about 330 km2. It is a part of the Inner Dinarides (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 sixteen karst springs (or scattered discharge zones) and nine (group of) wells, divided into five sectors. Average karst aquifer discharge of the whole area is calculated on 5.18 m3/s. Total minimum flow rate of the analysed karst springs and discharge zones is estimated at 1.2 m3/s, while the total flow rate of the analysed wells is estimated at about 0.3 m3/s, which makes about 1.5 m3/s of total (minimum) discharge. All analysed waters are low-mineralized (<1 g/l), while temperatures range from 9?35 ??. Use of the waters is multipurpose: municipal and local water supply, commercial bottling, recreational pools etc.

Highlights

Сумарна минимална издашност анализираних карстних извора и дренажних зона процењена је на 1.2 m3/s, док је сумарна издашност анализираних бунара процењена на око 0.3 m3/s, што чини сумарну (минималну) издашност од око 1.5 m3/s
“Valjevo karst” (Vk) covers the area from Valjevo-Mionica neogene basin (VMB), in the north, to the northern slopes of Valjevo Mountains range: Suvobor Mt., Maljen Mt., Povlen Mt., jablanik Mt, Medvednik Mt., in western Serbia, with a frame range of altitudes of app. 50–1350 masl (Fig. 1). on the Westeast direction, it is stretched from the jablanica river Basin to the Toplica river Basin
The dry river valley has a lot of ponor zones and the tracing tests showed groundwater traces to the Gradac springs (Fig. 2)

Summary

Introduction

Сумарна минимална издашност анализираних карстних извора и дренажних зона процењена је на 1.2 m3/s, док је сумарна издашност анализираних бунара процењена на око 0.3 m3/s, што чини сумарну (минималну) издашност од око 1.5 m3/s. Within this area an extensive karst aquifer is formed and is mostly drained by Paklje spring and Gradac springs (discharge zone) (MIjAToVIć, 1983; SIMIć, 1990). The dry river valley has a lot of ponor zones and the tracing tests showed groundwater traces to the Gradac springs (lAzAreVIć, 1996) (Fig. 2).
