Les recoupements karstiques de mandres encaisss, 1997, Nicod, Jean
Three types of cut-off can be observed: 1) by natural bridge or short tunnel: Pont d'Arc type self-piracy (Ardeche, France) ; 2) by caves system or hydrogeological network, Lesse type (Ardenne, Belgium) ; 3) subaerial in karstic environment, the case of Vis in Navacelles (Herault, France). The main processes are debated: anteriority or/and coexistence of the underground drainage, impact of neotectonics, of the load and the screes and of the water chemistry changes.

An example of identifying karst groundwater flow, 1998, Stevanovic Z. , Dragisic V. ,
Hydrogeological investigations for the purpose of regulating the karst aquifer were carried out in the mountain massif of Kucaj in the Carpatho-Balkan range of eastern Serbia. Different geo-physical methods were applied in order to identify the position of karstified zones with active circulation of karst underground streams. Especially good results were obtained by using the spontaneous potential method for the exploration and construction of boreholes and wells. In the valleys of Crni Timok and Radovanska reka the measurements have been carried out upstream along the whole width of the alluvium to the limestone periphery. A number of positive and negative anomalies have been recorded. In the centres of positive anomalies several boreholes were located: HG-19 (centre of anomaly 30 mV, total length of the biggest cavern is 9 m); HG-1 ( mV, cavern of 2m); HG-15 (max, ? mV, effective cavernousness is 17%)

Alpine (?) karst of Eastern Serbia, 1999, Zlokolicamandić, Milena, Ć, Alić, Ljubojević, Jelena

Eastern Serbia abounds in various karst features which could be classified into different traditionally determined types (tropical, alpine...), although it does not have either climatic or elevation parameters characteristic for those types. After introducing the basic postulates of the pure karst model, as well as the theories of inception and development, the fact which becomes evident is that, for example, Alpine and Dinaric karst differ only in dimensions and frequency of features, but not in the basic morphological characteristics. Eastern Serbia is an area which was explored more than a hundred of years ago (the area of classical explorations done by Jovan Cviji }). On the basis of the knowledge of that time, the karst of Eastern Serbia was determined as an example of the Jura type. In recent explorations, however, many entirely new facts have been established regarding sorts, dimensions, frequency and development factors of karst features. That is to say that the main difference lies in the extent of exploration and level of knowledge of an area, or, in other words, whether the karst is explored or unexplored.

Caves below collapse dolines - case study of Tisova Jama (Eastern Serbia), 2000, Ć, Alić, Ljubojević, Jelena, Ljubojević, Vladimir

The cave Tisova Jama (-235 m) is located on Beljanica Mountain (Carpatho-Balkanides, Eastern Serbia). Its entrance pit is situated at the bottom of a great collapse doline (dimensions 180 ¥ 160 m), below which there is a chamber with the greatest surface (11 374 m2) and volume (approx. 170 000 m3) so far known among Serbian caves. Such dimensions can be explained by the presence of a strong underground stream in the unreachable part of the cave. Removal of the material disrupts the stability of the rock below the doline, which leads to breakdown and deepening of the doline.

Natural bridges on the Vratna River (Eastern Serbia) as the last remnants of a former cave, 2000, Ć, Alić, Ljubojević, Jelena

The Vratna River is a right-side tributary of the Danube and its drainage area is situated at the western rim of the Dacian Basin. Along its 22 km long course, the Vratna flows through a 3,5 km long gorge cut in Tithonian limestones. Across the gorge there are three natural bridges, which shelter, in total 94 metres of the river course. There is a strong assumption that two of the natural bridges are the only remaining parts of roof of a former cave. Due to the process of surface denudation and to the disruption of stability, the cave roof almost completely collapsed, with the exception of these two sections. Several short caves and rock shelters exist in the gorge, and the longest cave (305 m) is situated next to the biggest of the three natural bridges.

On the genetic conditions of black manganese deposits from two caves of Eastern Serbia., 2001, Ljubojevic V. , Pafevski A. , Calicljubojevic J.
Portions of cave passages often have a black colour due to manganese deposits that occur as coatings on cave walls and ceilings, on clastic sediments, as well as on speleothems. On samples from the cave Buronov Ponor chemical analysis, infrared spectroscopy. X-ray diffraction and DTA analysis confirmed the presence of birnessite. In cave Cerjanska Pecina, the presence of manganese compounds in the black coating has been confirmed by chemical tests. In both caves it has been noted that cave passages with black coating have a distinct morphology. They are highly weathered showing an abundance of sharp prolusions, potholes in the streambed and scallops. The paper studies these occurrences and the possible link between the manganese deposition, hydrology and morphology of the passages and petrologic composition. Although this link was not identified, some interesting questions regarding manganese deposition arose. It remains unclear why manganese deposition is limited only to a certain part of cave Cerjanska Pecina, and what caused the cyclicity in manganese deposition in the cave Buronov ponor. manganese deposits, chemical analysis, speleomorphology

Karst features of narrow limestone belts - case study of the ridge Dževrinska Greda, Eastern Serbia, 2001, Ć, Alić, Ljubojević, Jelena

The paper presents several most interesting features of the ridge Dževrinska Greda (Carpatho-Balkanides, Eastern Serbia). Being 20 km long and, on average, 100-300 m wide, this narrow limestone belt is a typical polygon for contact karst and fluviokarst research. Beside examples of features such as through cave, through gorge, dry and blind valleys, there is also a discussion on types of contact (tectonic and sedimentary), impact of fluvial factors, directions of groundwater flow, etc.

Propagation of a floodwave in karst during artificially generated recession - case study of Banjica spring (Bela Palanka, Eastern Serbia), 2003, Zlokolicamandić, Milena, Jalić, Ljubojević, Jelena

During hydrogeological research in the area of the north-eastern foothills of Mt. Suva Planina in Eastern Serbia, a borehole of 100 m of depth was drilled in the vicinity of a lukewarm spring, Banjica. The borehole had an artesian discharge, which caused artificially generated recession in the adjoining spring Banjica. During this hydrodynamical test, great quantities of precipitation occured in the hinterland of the spring, having the effect of a floodwave. The presence of two types of karst is obvious in the field - confined karst and covered karst. The hydrogeological response to the floodwave during artificially generated recession proved the presence of deep-seated karst also. This can be detected by comparative analysis of the hydrograph of the Banjica spring and the graph of pressures in the borehole. In this way, not only the presence, but also the characteristics of the karst can be proved (e.g. dimensions and types of karst conduits, relative age of karst, size and extension of the aquifer, etc.).

Karst aquifer average catchment area assessment through monthly water balance equation with limited meteorological data set: Application to Grza spring in Eastern Serbia, 2013, Vakanjac Vesna Ristić, Prohaska Stevan, Dušan Polomčić, Blagojević Borislava, Vakanjac Boris

In the absence of detailed exploration of karstic catchments, the calculation of available reserves and elements of the water balance equation frequently reflect the topographic size of the catchment area, and not the actual, active (underground) size. The two differ largely where karst is concerned. The paper deals with the problem of average catchment area size estimation in the situation when meteorological data are limited to precipitation and temperature, but discharge records are available for long period. Proposed methodology was applied to, calibrated, and validated on 15 karst springs in Serbia. Results obtained with the model differ up to 20% from hydrogeological exploration results. One of investigated springs is Grza karst spring, which belongs to the karstic formation of Kučaj and Beljanica (the Carpatho­Balkanide Arch of Eastern Serbia). In this paper, we used the Grza Spring to show model application and necessary improvements to progress from graphoanalytical to analytical model. The average catchment area is linked to the model parameter that reduces potential to real evapotranspiration on monthly bases. The model potential lies in the possibility to determine not only catchment area, but real evapotranspiration and dynamic volume of the porous ­ karst groundwater storage as well.
