|TECHNOLOGY DEVELOPMENT PROGRAM (TR)|
Project number: TR-37005
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.
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 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.
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.
MULTIDISCIPLINARY RESEARCH PROGRAM
Project number: TR-41007
JCI researchers are taking part in one of the sub-projects, aimed at further development through adaptive design and fabrication of implants for clinical use (reconstructive surgery, tissue engineering). The focus is on modeling, simulation, testing, fabrication, optimization and clinical application.
Project number: III-43007
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.
FUNDAMENTAL RESEARCH PROGRAM
Project number: OI-176016
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).
