“Assessment of Climate Change Impact on Water Resources in Serbia”
Project Manager: Prof. Dr. Stevan Prohaska, Jaroslav Černi Institute for the Development of Water Resources, Belgrade

The objective of the project is to study the impact of climate change on Serbia’s water resources using the different climate change scenarios researched under Project III “Study of Climate Change and Impact on the Environment: Monitoring, Adaptation and Mitigation”. The task of the project is to define the reference (“zero”) status of surface water and groundwater resources and then, based on the climate change scenarios, predict the future status with regard to both quantity and potential regime change. One of the research components focuses on the assessment of changes to the temporal structure of available river discharge time-series, in terms of trend and cyclical/periodic pattern. A specific aspect is climate change impact on increasingly frequent floods and droughts, as well as the definition of protection and related risk management measures. Experimental research focuses on the assessment of climate change impact on agricultural drought and the quality and yield of crops as impacted by climate change. Crop production is also simulated to examine different climate scenarios, develop optimization guidelines and propose advanced technologies for better utilization of future water resources.

“Development of a Support System for Optimal Management of Large Dams in Serbia”
Project Manager: Prof. Dr. Dejan Divac, Jaroslav Černi Institute for the Development of Water Resources, Belgrade

Dam damage or breach can have extremely serious consequences, such that proper maintenance is required on a permanent basis. Maintenance includes structural monitoring of individual components and the entire dam, to identify and implement timely measures as needed to ensure dam safety and function.
The main objective of the project is to develop a support system for the implementation of a regulatory framework that will ensure large-dam safety and function, improve maintenance, and protect local communities and property. The project has developed a generic software platform of a service-oriented architecture that is highly modular and will be able to support different models and criteria in the future. The data templates and acquisition modules allow for upgrading of existing dam monitoring systems and data/document management. A special-purpose numerical model has also been developed to address coupled stress-and-strain problems and steady-unsteady flow through porous media. The support system has already been implemented at the Iron Gate 1 HPP dam, and the methodology verified thereby on a large structure and adapted to an existing complex monitoring and management system. It has also been implemented at Prvonek Dam, where the methodology was verified again to serve as an example of modern support systems for optimal dam maintenance in Serbia. A water permit is now pending. Upon approval, the outcomes of the development project will be integrated into the legal framework.

“Methodology for Assessing the Design and Maintenance of Groundwater Sources in Alluvial Environments”
Project Manager: Prof. Dr. Milan Dimkić, Jaroslav Černi Institute for the Development of Water Resources, Belgrade

The main objectives of this research project are to examine well ageing depending on the aerobic state of the aquifer/groundwater; to define and model the processes that take place during the course of bank filtration and artificial recharge (including transport of micropollutants, the nitrogen cycle and their effect on nitrate concentrations in alluvial groundwater); to develop a method for assessing fluid flow through a porous medium based on finite volumes, as applied in a software package currently being developed at JCI; to study and develop new technologies based on pulsed electrical discharges in water, as applicable to the maintenance of hydraulic structures; and to examine the impact of sanitation systems on water supply sources. The project outcomes are expected to help increase the amount of water extracted/extractable from both existing and new wells and to maintain or improve the quality of the raw water that is treated as needed before delivery to end users. The acquired knowledge and better understanding of the natural processes in the subsurface and rivers is expected to ensure that the solutions pertaining to the design of new or expansion of existing water supply sources, rehabilitation of existing and construction of new wells, establishment of operating modes of wells and groundwater sources, delineation of protection zones, and amendment of legislation are such that much better results are achieved then before in terms of the quantity and quality of extracted groundwater, while at the same time improving the cost-effectiveness of the development and maintenance of water supply sources.

“Biodiversity in Support of Ecoremediation Technologies for Damaged Ecosystems”
Project Manager: Prof. Dr. Vera Raičević, University of Belgrade, Faculty of Agriculture

Repair of damaged and endangered ecosystems based on ecoremediation concepts involves sustainable use of the natural ecosystem to conserve and protect the environment. There are numerous examples of aquatic and terrestrial ecosystems violated by improper waste disposal, wastewater discharges and the adverse effects of industry. One example is soil damage caused by the strip-mining operations of Kolubara RB, which have interfered with biodiversity. The project focuses on the creation of favorable conditions for the development of biotic ecosystem components. One of the key outcomes at the present stage is microbiological and chemical characterization of waste (sludge, etc.). A prerequisite for applying ecoremediation technologies is accurate characterization of damaged sites, including detailed characterization of plant species in areas where remediation measures had not been implemented over time, characterization of microbial activity in the rhizosphere of dominant plant species, collection of identified microbial populations in the rhizospheres of wild plants, and the development of reliable, sensitive methods for detecting microbial biodiversity in damaged ecosystems. Laboratory research under the project will result in a collection of autochthonous microbial populations that promote plant growth and microbial populations that colonize the roots of certain plant species as components of microbial consortia. The most effective consortium will be used for further research in the field, to optimize conditions for effective microbial consortium activity. The key outcome of the project will be the definition of conditions for using microbial consortia in damaged ecosystems, in combination with different types of waste and corresponding plant species.

“Study of Climate Change and Impact on the Environment: Monitoring, Adaptation and Mitigation”
Project Manager: Prof. Dr. Ratko Kadović, University of Belgrade, Faculty of Forestry

JCI specialists are involved in two sub-projects: 8. “Serbia’s water resources as impacted by climate change”, and 9. “Flashflood frequency and degradation of soil and water resources as a result of global changes”. The task of sub-project 8 is to assess the impact of climate change on Serbia’s water resources based on predictions of main future components of the water balance: precipitation, air temperature and evapotranspiration, which will be the outcomes of the study of climate change scenarios under sub-project 1 “Regional integrated geophysical model and climate change scenarios for Serbia”. This means that projects TR-37005 and III-43007 are being implemented in parallel and the outcomes shared interactively. Sub-project 9 basically addresses two main topics: soil and water degradation processes as impacted by global changes, and natural and anthropogenic drivers of flashfloods and potential control.

“Magmatism and Geodynamics in the Balkan Peninsula Since the Mesozoic: Formation of Metallic and Non-metallic Ore Deposits”
Project Manager: Prof. Dr. Vladica Cvetković, University of Belgrade, Faculty of Mining and Geology

JCI involvement in this project is related to the study of phenomenological geodynamic models – one-dimensional models of seismic fault movement, to define conditions that lead to earthquakes. The assessment is both analytical (local bifurcation analysis) and numerical (a Runge-Kutta algorithm). The study focuses on physical models of stick-slip movement, in the form of a series of blocks interconnected by springs, whose dynamic properties are described by systems of ordinary differential and delay equations. The outcomes of these models (systems of equations) and their trajectories for certain control parameters of the dynamic system indicate oscillatory, quasi-oscillatory and deterministic chaotic changes, which are interpreted as types of movement analogous to different phases of movements along faults (aseismic and seismic). The distribution of major events in the models (largest movements of all model bocks) can be described by the Gutenberg-Richter law of distribution of the number of events depending on their magnitude M, with a satisfactory degree of statistical accuracy. In this regard, JCI’s task is to determine the conditions under which model dynamics enter the stick-slip phase (seismic movement), through the introduction of new parameters (delay, seismic noise, transient and continuous external excitations) in models comprised of different numbers of blocks N (N=1-100), as well as to determine the distribution of major events (in the entire series of blocks and directly around the modeled hypocenter).
