Efekti regeneracije bunara na primeru Grabovičkog polja kod Kladova
Na mnogim izvorištima podzemnih voda javljaju se problemi smanjenja eksploatacionog kapaciteta kao posledica starenja bunara. Bunar tokom vremena menja svoje performanse, bilo da je u eksploataciji ili van radnog procesa. Na njegovo starenje utiče veliki broj faktora. Kao posledice javljaju se ekonomski, privredni i socijalni problemi. Regeneracija bunara je u praksi pokazala najbolje efekte za rešavanje ovih pitanja. Na prostoru Kladovskog ključa u priobalju Dunava koristi se drenažni sistem bunara za odbranu od visokih vodostaja. Prilikom provere stanja bunara ...Ivana Cvejić, Veselin Dragišić, Vladimir Živanović, Tijana Vinčić.

Analiza geomehaničke stabilnosti kosina na odlagalištima i površinskom kopu Ćeramide
Kako bi se nastavila eksploatacija dacita na površinskom kopu Ćeramide kod Rudnika, potrebno je izraditi novu projektnu dokumentaciju na osnovu novih overenih rezervi. Da bi se eksploatacija jalovine i dacita odvijala sigurno bez klizanja i obrušavanja stenskog materijala, neophodno je izvršiti proveru stabilnosti projektovanih kosina i na odlagalištima i na samom površinskom kopu. U ovom radu je upravo data analiza geomehaničke stabilnosti kosina na odlagalištima i površinskom kopu dacite Ćeramide kod Rudnika.Tomislav Šubaranović, Vladimir Čebašek, Bojan Dimitrijević, Veljko Rupar.

Wells calculation for the protection of opencast mine Radljevo North from groundwater
Za projektovanje kvalitetnog sistema zaštite jednog površinskog kopa od podzemnih voda bitno je da ulazni podaci budu verodostojni, kako bi se na osnovu njih izvršili potrebni proračuni objekata odvodnjavanja podzemnih voda. Proračunima za površinski kop Radljevo Sever je omogućeno da se dobije potreban broj bunara kako bi oni pravilno funkcionisali i obezbedili potrebno obaranje podzenih voda.Dušan Polomčić, Vladimir Petković, Miloš Jeremić.

Seasonal Variations of the Zapadna Morava River Water Quality
The water samples collected from four localities of the middle course of the Zapadna Morava River during 2020 were analyzed via the selected physicochemical parameters with the aim to estimate the quality of surface water. According to the results of selected physico-chemical parameters (pH, conductivity, dissolved oxygen, chemical oxygen demand, biochemical oxygen demand), analyzed surface water show a good chemical status, while the values of nutrient content (nitrate, nitrite, ammonium ion, total phosphorus) indicated the poor chemical status especially ...Nebojša Đ.

Geomechnical research for the new bucket wheel excavator testing at Open pit “Filijala”
Since 1976 cement marl excavation at open-pit mine „Filijala” is carried out by continuous exploitation technology using bucket wheel excavator SH 400 manufactured by Orenstein und Koppel (O & K) company. Due to the bucket wheel excavator time-worn and high operating cost it was necessary to replace it with new one. In order to test the new bucket wheel excavator and prove its capacity a testing zone was defined as test block for excavation, in which the bucket wheel ...Vladimir Čebašek, Nebojša Gojković, Veljko Rupar, Miodrag Pribićević.

Numerical Modeling and Simulation of the Effectiveness of Groundwater Source Protection Management Plans: Riverbank Filtration Case Study in Serbia
The paper describes the establishment and testing of an algorithm for developing sustainable management plans associated with groundwater source protection against potential pollutants and discusses the effectiveness of individual systems. The applied methodology pertains to groundwater resource management, particularly those cases that involve riverbank filtration. Namely, groundwater (numerical) modeling is employed to examine the groundwater regime and balance, as well as to create protection systems and illustrate their effectiveness. Particle tracking analysis is used to study pollutants’ travel and ...Dušan Polomčić, Dragoljub Bajić, Bojan Hajdin, Dragan Pamučar.

Contents of potentially toxic elements in residual soils of a long-term mining region: a key study from Central and Western Serbia
Milun Jovanović, Dejan Prelević, Vidojko Jović, Danica Srećković-Batoćanin, Snežana Branković (2022)Regional geochemical research of residual soil was conducted in an area of about 20,000 km2 in the region of Central and Western Serbia, where six metallogenetic zones and mining since ancient times have been documented. The geochemical background variation in the residual soil was established upon the contents, spatial pattern and natural background of potentially toxic elements (PTEs). The limits of natural background values (mg·kg-1) were determined by the integral method. Our data show that anomalous concentrations of As, ...Milun Jovanović, Dejan Prelević, Vidojko Jović, Danica Srećković-Batoćanin, Snežana Branković.

Probabilistic analysis of anisotropic rock slope with reinforcement measures
During the construction of E75 highway through Grdelica gorge in Serbia, a major failure occurred in the zone of reinforced rock slope. Excavation was performed in highly anisotropic Paleozoic schist rock formation. The reinforcement consisted of the two rows of micropile wall with pre-stressed anchors. Forces in anchors were monitored with load cells while benchmarks were installed for superficial displacement measurements. The aim of the study is to investigate possible causes of instability considering different probability distributions of the ...Zoran Berisavljević, Dušan Berisavljević, Miloš Marjanović, Svetlana Melentijević.

Karst groundwater quantity assessment and sustainability: the approach appropriate for river basin management plans
Veljko Marinović, Zoran Stevanović (2019)As a result of the fact that karstified rocks can accumulate large amounts of high-quality groundwater, karst aquifer is considered, throughout the world, one of the most important types of aquifers. Due to their high permeability, but also vulnerability to pollution, these precious groundwater resources need to be properly evaluated and protected. Taking into account heterogeneity and complexity of the karst environment, it is difficult to propose a uniform algorithm for managing karst groundwater, which causes the necessity to ...Upravljanje karstnim podzemnim vodama, Pritisci na kvantitet voda, Plan upravljanja vodnim resursima, Bosna i Hercegovina, SrbijaVeljko Marinović, Zoran Stevanović.

Mathematical modeling to define catchment size and real evapotranspiration (case study: Andrića karst spring, Western Serbia)
Marina Čokorilo Ilić, Vesna Ristić Vakanjac, Dušan Polomčić, Dragoljub Bajić, Jelena Ratković, Bojan Hajdin (2018)Water resources in karst are extremely important sources of drinking water supply. The quality of groundwater formed in karst aquifers is generally high and in most cases only chlorination is required. However, from a hydrogeological perspective, these water resources are the least studied. Often only basic information is available on catchment size, groundwater reserves (dynamic and static, if any) and groundwater balance. Detailed hydrogeological investigations and long-term monitoring of karst spring discharges are needed to acquire such information. In ...Marina Čokorilo Ilić, Vesna Ristić Vakanjac, Dušan Polomčić, Dragoljub Bajić, Jelena Ratković, Bojan Hajdin.

Hydrodynamic analysis application of contaminated groundwater remediation to oil hydrocarbons
U ovom radu sagledana je primena hidrodinamičke analize u okviru odabrane remedijacione metode ,,pumpanja i tretiranja” kontaminiranih podzemnih voda ugljovodonicima, na primeru pretakališta rafinerije nafte u Pančevu. Primenjena hidrodinamička analiza predstavlja pravilan, a sve češće i neophodan pristup u savremenoj hidrogeologiji. Prethodnim hemijskim analizama uzoraka tla i podzemnih voda na istražno-osmatračkim objektima detektovano je zagađenje produktima nafte. Novoizvedena istraživanja obuhvatila su izvođenje 12 pijezometara različitih dubina, geoelektrično sondiranje tla, ,,in situ” merenja prisutnog kontaminanta, izdvojenog kao hidrofobna faza LNAPL, ...Predrag Pajić, Aleksandar Čalenić, Dušan Polomčić, Dragoljub Bajić.
