Estimation of water quality of Sava River (Vojvodina, Serbia) in the period 2004-2011 using Serbian Water Quality Index (SWQI) IntroductionWater quality is one of the most significant factors that have to be taken into account in evaluation of sustainability of a particular region (Córdoba et al., 2010). The important aspects taken into consideration when examining the top-priority problems of water quality are the economic influence, the influence on human health, the influence on the ecosystem, the influence of the geographic area as well as the duration of the influence (Dalmacija, 2004).The quality of the watercourse at any of the points depends on several key influences: basin lithology, atmospheric influences, climatic conditions and anthropogenic influences (Shrestha, Kazama, 2007). River systems play an important role in the sustainable development of the entire environment, especially if they flow through inhabited areas (Kowalkowski et al., 2006). In order to provide the sustainability of ecological balance, the presence and quality of water are very important (Karadavut et al., 2011) and there have been more researches based upon water quality observing (Parvulescu, Hamchevici, 2010). Anthropogenic influences can cause negative consequencies in short period of time as far as water quality is concerned (Yunus, Nakagoshi, 2004), whereas waterbody pollution represents the result of human activities on one hand, and intensive urbanization development on the other hand (Dragićević et al., 2010). The organic solid load and the dynamics of its degradation are very good indicators of the anthropogenic im- AbstractA Water Quality Index (WQI) is a numeric expression used to evaluate the quality of water bodies and make it easier understood by managers. This paper aims to assess water quality of Sava River in Vojvodina (North Serbia) for the 2004 -2011 period. For this purpose authors applied: Serbian Water Quality Index (SWQI) assessment. WQI value is dimensionless, single number ranging from 0 to 100 (best quality) derived from numerous physical, chemical, biological and microbiological parameters. For the Sava River SWQI was mainly rated as very good. This study shows a clear decrease in water quality during warmer periods of the year. Additionaly, this study shows that water quality along Sava River decreases slightly downstream, of Sremska Mitrovica station but it still provides values that according to SWQI descriptive quality indicator have been defined as good (72-83) and very good (84 -89). Also, this study shows an increase of SWQI downstream of the confluence of Drina River into Sava River. This methodology includes parameters for assessment of organic loading, but does not involve parameters of heavy metals concentration.
This paper evaluates the application of the Normalised Difference Vegetation Index (NDVI) in the monitoring and assessment of temporal vegetation cover changes (from 2006 to 2014) in three municipalities of Central Serbia: Topola, Jagodina and Kuršumlija. Additionally, special focus is placed on the analysis of the forest areas and the possible use of NDVI in the forest management sector. Results of the NDVI applied through Idrisi software identify all vegetation cover types and their typical values for presented case studies and observed periods. Obtained results for Serbian case studies indicate two major observations outlined for the investigated period. It was noticed that vegetation cover is experiencing a certain decrease, and that certain discrepancies exists between the NDVI and official forest area statistics for certain municipalities. The study outlines the positive outcomes of the applied remote sensing techniques, especially for southern Serbian municipalities where illegal logging activities are pronounced. Hence, this method proved very promising for countries performing national forest inventories, such as Serbia, providing local forest managers with several essential up-to-date information about vegetation cover changes on an annual basis.
⎯ This study presents the climatic and bioclimatic conditions at Zlatibor, as well as their modification and distribution over the year. Zlatibor Mountain is a popular tourist destination in Serbia, and it stands out as a mountain of exquisite natural and anthropogenic values. Information about climate and bioclimate is presented by using physiologically equivalent temperature (PET), and universal thermal climate index (UTCI) over 10-day periods. The Climate-Tourism/Transfer-Information-Scheme (CTIS) was also used as it displays climate and bioclimate information for tourism purposes based on thresholds of relevant parameters and the frequency of occurrence. The weather suitability index (WSI) was calculated as well, because it provides synthetic information about suitability of weather for different forms of recreational and tourism activities. The results obtained in this study were used to develop a bioclimatological leaflet for Zlatibor, which could be very useful to the tourism industry and stakeholders in decision-making, but also it will enable tourist to choose the best time for holiday depending on personal preferences and requirements.
Renewable energy sources play an important role in the future not only for the European countries, but for many countries worldwide. Most cost-effective and reliable large wind energy conversion systems are becoming the main focus of wind energy research and technology development, all in order to make wind energy competitive with other more traditional sources of electrical energy like coal, gas and nuclear generation. Serbia, along with neighbouring countries, has a high potential for developing energy production from renewable energy sources. Wind energy in Serbia, despite its great potential, is only partly studied and insufficiently used. This study aims to provide summary of wind energy potentials in the region of Vojvodina, which is an important economic region in northern Serbia. Its existing electrical energy status is thoroughly investigated according to the recent developments of wind energy production on global, regional and local scale. The main purpose of this study is the implementation of energy efficiency concept with purpose of satisfying the needs of Serbian electricity market.
