1998
Marcetic, I. (Rudarsko-geoloski fakultet, Beograd (Yugoslavia). Institut za hidrogeologiju) | Prohaska, S. | Srna, P. | Isailovic, D.
In this paper the short review of the results of calculation of the coincidence between the water level and quality parameters at the gauging station Cuprija-rail bridge (Serbia, Yugoslavia) is presented. The basic principles of the applied method and criteria for the estimation of the statistic significance of coincidence indicators are given. At the end of the analyses and comments of the obtained results, as well as the possibility for application of this methodology are given. The paper gives numerical quantities of the estimated indicators of statistical significance of the coincidence of water level and quality parameters of groundwater. Also, the graphical illustration, which shows the common exceeding probabilities of the water level and quality parameters, is presented.
Mostrar más [+] Menos [-]Possibility of using bottom fauna community as an indicator of the condition of the river ecosystems
1998
Simic, V. (Prirodno-matematicki fakultet, Kragujevac (Yugoslavia). Institut za biologiju)
In Yugoslavia, application of macrozoobenthos for the purpose of bioindication has been relatively limited. This communities has been used in conjugation with saprobiological methods, while biotic indexes have been unjustifiable used to a small extent. This paper shows the most significant biotic indexes used in the World and possibility of their application in Yugoslavia, as well as the necessity for their modification and elaboration of new ones specific to Yugoslav conditions.

Maksimovic, M. (Prirodno-matematicki fakultet, Novi Sad (Yugoslavia). Institut za hemiju) | Vojinovic-Miloradov, M. | Matavulj, M. | Mihajlovic, B. | Buzarov, D.
The aim of this paper is to find out the most efficient method of determination of toxic PCB in the natural way in aquatic system. According to the preliminary research, positive degradative response of PCBs was obtained by the selection of micro fungi species.
Mostrar más [+] Menos [-]Water quality in Yugoslav part of the river Tisza [in the period of 1988-1995] evaluated with method of multiobjective iterative compromise optimalization (MICO)
1997
Krizan, J. (Univerzitet u Novom Sadu, Novi Sad (Yugoslavia). TEMPUS centar)
The aim of this paper is to survey and point to the critical parts of this typically valley river in the chosen period of time, which is, because of its low flow, small turbulence and exceptional social and industrial significance, very susceptible to ecological catastrophes. This paper contains the elaborated state of water quality in Yugoslav part of the river Tisza, during two periods of observation, with usual (1988-1991) and specific (1992-1995) river ecosystem exposure to pollutants. The average annual data of concentration for characteristic parameters in the monitoring stations were compared with method of multiobjective iterative compromise optimalization (MICO) of the influence that different categories of polluters have on the river ecosystem. On the basis of analyzed concentrations of selected parameters and results obtained with method of MICO, it is possible to conclude that the improvement in quality of Yugoslav part of the river Tisza has occurred during the period of 1992-1995.
Mostrar más [+] Menos [-]Analysis of drought characteristics using renewal processes
1997
Vukmirovic, V. | Petrovic, J. | Lazic, R. (Univerzitet u Beogradu, Beograd (Yugoslavia). Gradjevinski fakultet)
Drought characteristics (minimum flows, drought duration and volume deficit) of the Moraca river near Podgorica, Montenegro (Yugoslavia) are analyzed using the peaks over threshold method based on renewal processes. It is also shown that volume deficit and drought duration are highly correlated.
Mostrar más [+] Menos [-]Criteria for obtaining quality indicators of surface waters: an example of the South Morava river basin [Serbia, Yugoslavia]
2001
Veljkovic, N. (Vodovod, Leskovac (Yugoslavia)) | Milenkovic, S. | Dopudja-Glisic, T.
The work gives the regime of surface water flows with hydrographic net and the regime of waters at hydrologic stations for the period of 1988-1998. Consequently in this paper will be designed a resonant indicator which is derived out of the composite index group of WQI for the flow field in the period under research. Depending on the index points won at the examined profiles, estimation of waterflows quality will be adapted to the goals of indicator users, in this case to the public. Indicators of the type very poor, poor, good, very good and excellent. Hereto it is important to mention that hereby validity of original composite indicator will have to be sacrificed.
