Effect of pluviographic parameters and runoff on suspended sediment concentration in small streams
1998
Stefanovic, J. | Bulajic, Z. (Institut za zemljiste, Beograd (Yugoslavia))
Hydrological, psamological and pluviographical measurements in experimental watershed area in the watershed of River Topciderska (Serbia, Yugoslavia) was analyzed. Interrelations between suspended sediment concentration in streams on the one hand and runoff, rainfall, rainfall intensity and index of previous rainfall on the other hand was came from this analyze. Effects of these parameters on suspended sediment concentration was considered for a single rainfall epizode, during the period of torrential waves and as annual value. Specific coefficients (coefficient of annual rainfall structure and coefficient of annual runoff structure) were used in this paper, with help of them effects of torrential waves and intensity rainfall on average annual suspended sediment concentration were considered.

Popovic, V. (Institut za zemljiste, Beograd (Yugoslavia)) | Ivanovic, S. | Ivanovic, S. | Petrovic, P.
In this paper, we are consider processing of soils erosion and his way on protection expoitation of water for population water supply, melioration's systems for irrigation and for strew of manger of the Lim river with the tug and suspend bank (Montenegro, Yugoslavia). We are given suggestions for protective utilization of agricultural and forest lands and the possibilities of water exploitation from Bistrica river (Montenegro, Yugoslavia). That is useful for fishing, irrigation, energetic, tourism and water supply. In this paper, you can meet some suggestions about exploitations of minerals and organic fertilizars that are not toxics and they not any influence on pollution of land and water.

2001
Talevski, T. (Hidrobioloski zavod, Ohrid (The Former Yugoslav Republic of Macedonia))
In this paper are presented autochthonous and all other alochthonous famous fishes in Lake Ohrid and its catchement area (The Former Yugoslav Republic of Macedonia). Introduction of new species in lakes and rivers in the Former Yugoslav Republic of Macedonia is prohibited, especially in Lake Ohrid and catchement area. The most probable period and possible way of introduction are presented and the reason of that introduction, as well. It is necessary, in the future, more attention to be paid on Lake Ohrid protection from introduction of new species, which may cause big changes in Lake Ohrid dynamics.

1997
Brajkovic, M. (Institut za vodoprivredu "Jaroslav Cerni", Beograd (Yugoslavia)) | Gavrilovic, Z. | Vukmirovic, M. | Dakovic, S.
Problems encountered in evaluating surface water quality arise from the requirements of relevant regulations that these evaluations should be made in the last favourable hydrologic conditions during design flow rate (required minimum flow). However, the major part of measurements of water quality parameters is not performed under such conditions and the result must be corrected for the conditions under required minimum flow. Two possible approaches to solving this problem are presented in this paper and explained using an example of the Juzna Morava river basin up to the Station Korvingrad, Serbia (Yugoslavia). This basin is unhomogeneous regarding its hydrologic characteristics and mass flow of pollutants. The results of analysis are presented in the cartography form using the GIS technology.

Potential erodibility of small watershed on the base of their geological structure
1999
Stefanovic, J. | Bulajic, Z. | Stefanovic, S. (Institut za zemljiste, Beograd (Yugoslavia))
There was investigated potential erodibility of two small experimental watersheds, which belongs to the watershed of Topciderska river, Serbia (Yugoslavia), on the base of geological structure of the watershed area. The investigations of potential erodibility of watersheds were included the analysis of tectonical and every geological formation, as from viewpoint of its possible erodibility as well as of possible sediment type (load, suspended and mixed) which were originated in desintegration processes. The sediment type domination, which was produced from watershed, was confirmed from granulometric composition of sediment in experimental watersteams. The synthesis of results of this analyses is presented with map of potenatial source of sediments from experimental watersheds.

1999
Bozovic, M. (Savezno ministarstvo za razvoj, nauku i zivotnu sredinu, Beograd (Yugoslavia))
The main characteristics of catchment area of Boka Kotorska Bay (Adriatic sea, Montenegro, Yugoslavia), are high slope, carstic structure of ground, high precipitation (over 5000 mm a year) and high run-off of rain water. All rainwater is transported trough carstic ground structures quickly appearing in numerous sources along the sea cost or ones located on the bottom of the Bay. The large volume of freshwater which permanently empty into the Bay has the strong influence on the aquatic environment (salinity, temperature, transparency, etc.) and biota (abundance of the species) as it has been observed in the parts of Boka Kotorska Bay (i.e. Morinj and Risan Bays). The abundance and number of species are the good indicator of changes of aquatic environment and hydrological changes as well as of the capability of aquatic organisms to adapt quickly on the severe changes of conditions.

1999
Popovic, V. (Institut za zemljiste, Beograd (Yugoslavia)) | Spalevic, V. | Petrovic, P.
In this paper sediment production and sediment discharge and its influence on hydroenergetical potential as well as pollution of river Lim - upper flow, Montenegro (Yugoslavia), were taken into consideration. Besides of problems of sediment and water discharge protection - biological and technical measures for sanation the negative effects of erosion processes were recommended. Total annual sediment production for the river Lim - upper flow was 679,763 mE-3/year and annual sediment discharge was 312,013 mE-3/year. Such sediment (produced and discharged) has negative impact on the hydroenergetical potential and soil resources and also pollutes water with sediments and other harmful and hazardeous materials. Introduction of erosion control measures will reduce the negative effect of erosion on the tolarant level.

One of the most important strategic-development directions of Serbia in the 21st century is restoration of hilly-mountainous regions. Stara Planina represents the region with extraordinary natural potentials almost unused, especially the part upstream of the reservoir Zavoj. Development of sheep raising on huge meadow-pasture surfaces in the catchment of river Visocica is possible, taking into account natural characteristics of the area, education and tradition of inhabitants. Catchment area of river Visocica provides water for water-supply reservoir Zavoj, so it is very important to apply erosion control measures on the slopes, as well as stopping the eroded material and pollutants before reaching the water courses. Agroforestry is optimal system of land use, with indispensable conservation and protective measures.

Since the water from the intergranular aquifer of Cemovsko Polje (Montenegro) represents an invaluable drinking water reserve, which can also be used for irrigation, the check up of the aquifer revealed that it is being infiltrated by pollutants from somewhere within the catchment area. The results have shown that the mentioned water from the intergranular aquifer (T3 and T4) is influenced by the agricultural activities in the area, leakage from the uncontrolled landfill of Podgorica, depending on the hydrological conditions, and, to a smaller degree, by the quality of the surface waterflows, with which it is connected.
