Imputing missing data using grey system theory and the biplot method to forecast groundwater levels and yields
Groundwater management is one of today’s important tasks. It has become necessary to seek out increasingly reliable methods to conserve groundwater resources. Dependable forecasting of the amounts of groundwater that can be abstracted in a sustainable manner requires longterm monitoring of the groundwater regime (rate of abstraction and groundwater levels). Monitoring of the groundwater source for the town of Bečej, Serbia had been disrupted for multiple years. The objective of the paper is to assess the possibility of reinterpreting ...Jelena Ratković, Dušan Polomčić, Zoran Gligorić, Dragoljub Bajić.

Ocena zaštitne funkcije povlatnih slojeva izvorišta Jasik (Opština Batočina) primenom GLA metode
U cilju utvrđivanja rezervi podzemnih voda i analize uslova zaštite u periodu 2012. i 2013. godine, sprovedena su detaljna hidrogeološka istraživanja na području izvorišta Jasik (opština Batočina). Uspostavljen je sistem monitoringa, čiji je rezultat predstavljao prikupljanje detaljnih hidrogeoloških podataka. Za potrebe analize, izrađen je hidrodinamički model, na osnovu koga je simulirano kretanje podzemnih voda, odnosno, utvrđene zone sanitarne zaštite. Pored navedenog, za potrebe utvrđivanja uslova zaštite podzemnih voda, bilo je neophodno utvrditi podložnost aluvijalne izdani izvorišta Jasik zagađenju.

Determining the Groundwater Balance and Radius of Influence Using Hydrodynamic Modeling: the Case Study of the Groundwater Source “Šumice” (Kikinda, Serbia)
A groundwater flow model was developed to simulate groundwater extraction from the public water supply source of the City of Kikinda. The hydrodynamic model includes the municipal groundwater source of Kikinda (Šumice and the Jezero Well), but also an extended area where there are groundwater sources that provide water supply to three factories: (MSK, TM and LŽT - Kikinda). Hydrodynamic modeling, based on the numerical method of finite differences will show the groundwater balance of the sources in the ...... was developed to simulate groundwater extraction from the public water supply source of the City of Kikinda.

Vulnerability methods in hard rock formation as a basis for groundwater risk assessment – from resource to source
Groundwater in a hard rock formation is most endangered at places where a potential source can discharge contaminants that can reach the saturated zone of an aquifer. In these circumstances, an essential tool for groundwater protection is the contamination risk map. This map is based on the integration of two maps: a hazards map, i.e., map of potential sources of contamination and a vulnerability map. The selection of a proper vulnerability method is an important task since the resulting ...karta rizika od kontaminacije, ranjivosti podzemnih voda, DRASTIC, EPIK, PI, COP, Nacionalni park TaraVladimir Živanović, Igor Jemcov, Veselin Dragišić.

Postojeće stanje i budući trendovi u preventivnoj zaštiti podzemnih voda Srbije
Vladimir Živanović (2022)Podzemne vode predstavljaju osnovni, a u mnogim zemljama i jedini resurs za javno vodosnabdevanje stanovništva tako da zaštita podzemnih voda predstavlja bitan preduslov za njihovo dugotrajno i održivo korišćenje. Kako u svetu, tako i u Srbiji, zaštita podzemnih voda se najvećim delom svodi na primenu preventivnih mera zaštite. Kod planiranja zaštite većih prostora sve više se koriste metode za ocenu ranjivosti podzemnih voda.

Climate change and their imapct on karst groundwater
Milan Đelić, Vesna Ristić Vakanjac (2021)In the last 30 years, there have been progressively more dry and rainy years, a reduced presence or even absence of snow cover, an increase in air temperature, large-scale fires, intensified glacier melting, and the like. Climate change certainly has an effect on all areas of economic activity, but its largest impact is on water resources and existing ecosystems. One of the most important water resources is groundwater, on account of which more than 70% of the population of ...Milan Đelić, Vesna Ristić Vakanjac .

Hydrochemistry of groundwater contaminated by petroleum hydrocarbons: the impact of biodegradation (Vitanovac, Serbia)
Nenad Marić, Jana Štrbački, Sanja Mrazovac Kurilić, Vladimir P. Beškoski, Zoran Nikić, Snežana Ignjatović, Jovana Malbašić (2020)Aquifer contamination by petroleum hydrocarbons leads to measurable changes of groundwater hydrochemistry, primarily due to the microbiological activity. This study analyzes this phenomenon at an historical kerosene-contaminated site in Vitanovac (central Serbia). Due to the long-term hydrocarbon contamination and exposure to aerobic and anaerobic biodegradation mechanisms, the lowest concentrations of O2, NO3−, and SO42− (electron acceptors) and the highest concentrations of Mn and Fe (products of microbial metabolic activity) overlap. The terminal redox-accepting processes in groundwater ranged from oxygen ...Nenad Marić, Jana Štrbački, Sanja Mrazovac Kurilić, Vladimir P. Beškoski, Zoran Nikić, Snežana Ignjatović, Jovana Malbašić.

Ocena kvaliteta i mogućnost korišćenja podzemnih voda za piće i navodnjavanje u slivu reke Ralje
Analiza mogućnosti korišćenja podzemnih voda za potrebe vodosnabdevanje stanovništva kao i za navodnjavanje vršena je na prostoru sliva reke Ralje. Istražni prostor veličine oko 280 km2 je obuhvatio veći deo sliva reke Ralje koji se administrativno nalaze na području grada Beograda. Podzemne vode su glavni izvor za vodosnabdevanje i navodnjavanje u ovom području. Seoska naselja nemaju urađenu komunalnu infrastrukturu pa predstavljaju značajan faktor za degradaciju kvaliteta podzemnih voda na ovom području.

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.
