To what extent reactivated faults are (not) responsible for karst process: example from Serbian Carpatho-Balkanides?
Ana Mladenović, Jelena Ćalić (2023)Carpatho-Balkanides represent part of the complex Dinaric – Carpatho – Balkan orogenic system, that geomorphologically dominates the central part of the Balkan Peninsula. The existence of this orogenic system is a result of closure of the Neotethys ocean and subsequent convergence of the Adriatic microplate and the Eurasian continent, that has been still active in the recent times. Such geodynamic characteristics conditioned complex tectonic structures, multiply reactivated during Late Cretaceous and Cenozoic times. The main aim of this work ...Ana Mladenović, Jelena Ćalić.

Density maps from gravity inversion as a tool for the basin basement analysis and imaging
Ivana Vasiljević (2023)Previously devised method for density mapping of the Cenozoic basin’s basement is further developed in order to improve the visualization and geological interpretation of the results. The method combines gravity-density inversion with forward modeling and requires gravity anomaly and depth-to-basement data. Although it was primarily designed for application in well-researched basins, such as Pannonian basin, method does not require further constrains. An information on density distribution in the Cenozoic sediments (from density logging or core density measurements) is important ...Ivana Vasiljević.

Agent-based modeling as a support to an expert-based approach: Exploring individual heating systems transition
Expert-based energy scenarios are mainly developed following assumptions of experts and, in most cases, a limited number of stakeholders. Such an approach will provide satisfactory results in centrally managed energy sectors where further decisions could be envisaged relatively precisely (electricity production/distribution, district heating systems, etc.). The same approach will provide more uncertain outcomes of future energy structure in the household sector, where decisions related to consumption, selection of energy source, or application of specific technology are made by numerous ...Energetska tranzicija, Grejanje domaćinstava, Individualni sistemi grejanja, Energetsko planiranje, Integrisano energetsko planiranje, ABM, LEAP, SrbijaBoban Pavlović, Marija Živković, Dejan Ivezić.

Linearization of Input Signal as a Necessary Tool in Stochastic Modeling of Karst Groundwater
Veljko Marinović (2021)Modelling of karst hydrogeological systems is a very complicated task, bearing in mind that for a deterministic model one should know the internal physical processes of precipitation transformation into discharge, while for a stochastic model nonlinear dynamic systems such as karst should be simulated by linear regression equations. Stochastic models need linearization of input time series due to often large residual in the recession period. This occur because the model is not able to absorb single rain episodes, which ...Veljko Marinović.

The impact of temporal variability of groundwater levels on groundwater vulnerability maps in karst terrains – a case example of the Perućac spring catchment area
Groundwater vulnerability maps represent an essential tool for protecting karst groundwater resources. Vulnerability assessment is usually based on spatial evaluation of various parameters that affect the vulnerability degree and regulate the protection role of the unsaturated zone. Most of these parameters, like soil and geology conditions, are constant and do not change during the year or over several years. In contrast, some parameters, such as the groundwater level, depend on the variability of recharge conditions. By considering the variability ...Vladimir Živanović, Igor Jemcov, Nebojša Atanacković.

Hydrochemical indicators of groundwater flow in the area of “Čukaru Peki” Cu-Au underground mine in eastern Serbia
The physical and chemical properties of groundwater, together with the groundwater levels regime and rock hydraulic properties, are often used to understand and conceptualize the hydrogeological system. Prediction of the influence of mining works on groundwater, and vice versa, is a challenge due to significantly altered groundwater flow patterns in the raw materials exploitation areas in relation to natural conditions. Therefore, multiple parameters are assessed and monitored before and during exploitation to properly characterize and quantify the system for ...Nebojša Atanacković, Vladimir Živanović, Jana Štrbački, Veselin Dragišić, Ivana Cvejić.

Validation of vulnerability assessment by means of the Time Dependent, Model: case study from the Slovenian karst catchment
Groundwater vulnerability assessment methods are continuously being developed and existing methods are very often modified to provide better simulation of natural protection conditions and more objective results. Most frequently used methods are based on calculation of predefined parameters influencing water infiltration and underground flow, which can often lead to bias conclusions related to vulnerability evaluations. Some other methods, like the Time Dependent Model (TDM) are based on an approach, where parametrization is obtained at the final stage of the ...Ocena ranjivosti podzemnih voda, karstne podzemne vode, TDM metoda, delineacija sanitarnih zona, Slovenački karstVladimir Živanović, Nataša Ravbar, Igor Jemcov.
