  • Stanje i perspektivnost vodosnabdevanja Obrenovca i naselja opštine posle poplava, 2014. godine

    Bojan Hajdin, Dušan Polomčić, Dragoljub Bajić (2017)
    Obrenovac i okolna naselja su tokom 2014. godine zbog poplava u Srbiji pretpeli veliku materijalnu štetu, a pored brojnih privrednih preduzeća ozbiljno je bio ugrožen i sistem vodosnabdevanja. Izvorište „Vić bare“ za vodosnabdevanje grada u selu Zabrežje, na Savi, u potpunosti je potopljeno, a vodovodna mreža, u pojedinim delovima već veoma stara, dodatno je oštećena. Poslednjih nekoliko decenija kao glavni razlozi za probleme u vodosnabdevanju Obrenovca isticane su nedovoljne rezerve podzemnih voda na izvorištu. Novijim istraživanjima utvrđene su rezerve ...

  • Failure Estimation of the Majdanpek Open Pit East Face Based on Inverse Velocity Model

    Miloš Marjanović, Stefan Milanović, Nikola Simić, Lazar Kričak (2024)
    The Majdanpek open pit mine south district is currently active mining prospect of copper ore exploitation in eastern Serbia. Its depth is approaching the termination depth and occurrences of large-scale instabilities and global instability of the final pit slope is possible. These can generate catastrophic mass movement inside an area that encloses a regional road route and the Pek River bed which is channelled along the outer contour of the pit. The displacements that were noted in early 2023, in the ...

  • 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 ...

  • A contribution to the understanding of the discharge dynamics and water balance of the karst spring Gornji Dušnik (Suva Planina)

    Aleksandar Tanasković, Vesna Ristić Vakanjac, Dušan Polomčić, Jelena Ratković (2023)
    A sufficiently long time-series of daily discharges is needed to assess the discharge dynamics and calculate the water balance equation parameters of a spring (river source). The paper assumes that a catchment is gauged if a time-series of observations of at least 30 years is available, which is a rare case in Serbia. One-year monitoring is often set up to verify the reserves of a water source or spring intended for capture. Monitoring ceases after the final report is ...

  • Environmental flows and demands for sustainable water use in protected karst areas of the Western Balkans

    Zoran Stevanović, Aleksandra Maran Stevanović, Želimir Pekaš, Romeo Eftimi, Veljko Marinović (2021)
    Karst terrains cover some 30% of the Western Balkans, where rich karst aquifers represent the main source of potable water supply and ensure the development of local economies and tourism. In this “classical karst” region, there are also numerous sites or areas under different forms of protection—from those that are included in the UNESCO World Heritage list to natural monuments and landscapes that are protected by national legislation.

  • The Importance of Geotechnical Investigations for the Construction of Transfer Station „Prelići“ on Landfill in Cacak – Serbia

    Dragoslav Rakić, Irena Basarić, Jovana Janković, Tina Đurić (2019)
    For the purpose of the facilities construction within the transfer station „Prelici“ in Cacak, specific geotechnical investigations were carried out based on which the technological project with the facilities schedule was developed. Significant deviations in relation to the presented results were determined during earthworks, so the additional geotechnical investigation works were carried out. Since the new investigation works have determined a different cross section of the terrain, it was proposed to move the planned facilities which led to the ...

  • Synergy between the mineral deposit exploration and geothermal resources assessment on the example of "Valjevo" boron and lithium deposit in Serbia

    Nebojša Atanacković, Vladimir Živanović, Ana Vranješ, Sava Magazinović, Marinko Toljić, Ana Arifović, Branislav Potić (2023)
    Exploration of mineral deposits involves a collection of vast data sets on geological characteristics of the area. These data can largely contribute to the assessment of the geothermal potential, which can lead to an increase in the share of geothermal resources in the energy mix of the extractive industry and the local community. On the example of the "Valjevo" B-Li deposit, data on structural settings and previous hydrogeological investigations were combined with the results of resource drilling and geophysical ...
