This paper shows the results obtained in field analysis performed at the Tamis River, starting from the settlement Jasa Tomic - border between Serbia and Romania to Pancevo - confluence of Tamis into the Danube. The Tamis is a 359 km long river rising in the southern Carpathian Mountains. It flows through the Banat region and flows into the Danube near Pancevo. During the years the water quality of the river has severely deteriorated and badly affected the environment and the river ecosystem. In situ measurements enabled determination of physico-chemical parameters of water quality of the Tamis River on every 400 m of the watercourse, such as: water temperature, pH value, electrical conductivity, contents of dissolved oxygen and oxygen saturation. The main reason of higher pollution of Tamis is seen in connection to DTD hydro system. Sampling was performed at 7 points with regard to color, turbidity, total hardness, alkalinity, concentration of ammonium nitrogen, nitrite nitrogen, nitrate nitrogen, iron, chlorides and sulphates in samples. The aim of the present work was to evaluate water quality in the Tamis River taking into account significant pollution, which originates from settlements, industry and agriculture, and to suggest appropriate preventive measures to further pollution decreasing of the river's water.

Water Quality Indicators

For forecasting of the change of water quality in water object the geographic information system (GIS) of the ecological monitoring had been designed. The geographic information system was applied to analyze the water quality of the Danube and Seversky Donets. With the help of GIS, the main trends of changes in water quality indicators of the Danube Delta were identified. In the Danube River, for the most part, there was a tendency for improvement of water quality during the study period, the tendency for deterioration of water quality was determined only by the indicator of manganese. The tendency for deterioration of water quality was observed in the Siverskyi Donets River by the following indicators: suspended matter and ammonia nitrogen. The main trends of changes in water quality indicators have also been identified in the lakes (Chaika, Lychevoe), which influence the formation of water quality of the Siverskyi Donets River. In Lake Chaika there is a tendency to deteriorate in quality: weighed substances; nitrogen nitrate, chlorides and iron. In this case, the values of some indicators in Lake Chaika (BOD-5 and total iron), in Lake Lichovo (COD, BOD-5, nitrite nitrogen) and in the Siverskyi Donets River (overlying districts, ammonium nitrogen) will be several times higher fishery maximum permissible concentration.

a spatio-temporal analysis of the main indicators of the water quality of the Hodza River, the change in time of water quality along the river under the conditions of anthropogenic impact is carried out. In general, the waters of the river are characterized as “extremely dirty”. Among the pollutants, iron and ammonium nitrogen compounds absolutely prevail. There is a tendency to some improvement in the quality of river waters downstream. In the upper reaches, the COD is 1.7 and 2.5 times higher than in the middle and upper reaches; BOD – 1.6 and 2.3 times, respectively.

Abstract Fish farming and especially rearing and breeding of rainbow trout and carp is one of potential sources of surface water pollution. The study was aimed at assessing the effect of a rainbow trout farm on water quality in the Gowienica River in winter. Temperature, pH, electrolytic conductivity, total suspended solids, dissolved oxygen, BOD5, CODCr, alkalinity, water hardness, calcium, magnesium, ammonium-nitrogen, nitrate-nitrogen (III and V) and total phosphorus were determined according to Polish Norms and APHA [1995] in water samples collected in winter up- and downstream the study object. The increment of pollutant concentrations in rainbow trout farm effluents was referred to the requirements in Rozporządzenie MŚ [2006]. Performed studies and literature review show that effluents from the assessed fish farm did not worsen water quality of the river. Increased concentrations of total suspended solids and CODCr in effluents were noted only in March. According to data from the report on environmental status in zachodniopomorskie province in the years 2008-2011, poor water quality of the Gowienica River is recorded already upstream the rainbow trout farm. Pollution of this stretch of the river may originate from uncontrolled waste water management and from nutrient runoff from fields.

In this study, it is aimed to determine the water quality of Kahta Stream which is poured into Atatürk Dam Lake by following some hydrological and physico-chemical characteristics between April 2012 and March 2013. For this purpose, monthly measurements were made at five stations from the source to the downstream and water samples were taken. During the monitoring period, water temperature 5.0-25.2 °C; electrical conductivity 216-359 μS/cm; total dissolved solids 147-244 mg/L; dissolved oxygen 8.67-13.36 mg/L and pH were measured in range of 7.08-8.76. Suspended solid 2-138 mg/L; turbidity 0.92-96.70 NTU; total alkalinity 102-200 mg/L; chloride 0.71-5.02 mg/L; ammonium nitrogen 0.007-0.400 mg/L; nitrite nitrogen 0.003-0.060 mg/L; nitrate nitrogen 0.12-1.19 mg/L; dissolved reactive phosphorus 0.007-0.033 mg/L; silica 5-23 mg/L; sulphate 8-33 mg/L and chemical oxygen demand were determined betwen 0.63-9.18 mg/L. Kahta Stream with slightly alkaline character, in terms of the parameters monitored, it is determined that the Surface Water Quality Regulation has the characteristics of Class I (high quality water) according to the Environmental Quality Standards. With this characteristic, it has been determined that Kahta Stream has a high potential to be used for drinking water supply, it can be used for re-use, trout farming, animal production and other farm needs. In addition, when the temporal relationship of variables was analyzed statistically, a significant difference was found among all variables except SiO2 (p <0.05). This result shows that the variables are affected by seasonal changes.

This paper aims to investigate the effects of natural variables, including precipitation and flow rate, on the quality of the Zarjoub River in Guilan province, Iran. The new hydrological insight in this study is a lack of national research focused on the dual effects of rainfall and flow rate on river water quality in coastal areas along the Anzali Wetland. To investigate the effect of precipitation and flow rate on river water quality, nine water quality variables were monitored during the 10-year period. In this article, (a) the existence of trends and the best fitted models of water quality parameters and the discharge and precipitation were analysed using statistical techniques and (b) the relationships between concentration of constituents with the discharge and precipitation on the up-stream and middle station were also examined. Box plots, for explaining the distribution of a data collection, were used. The results showed the existence of trend of water quality parameters with river flow and rainfall. As presented in Section 3, with increasing precipitation and flow rate, concentration of all constituents, except pH and SO₄2, decreased. On the contrary, the maximum amount of water quality elements was observed in low precipitations; therefore, the maximum concentration occurred in less than 15 mm precipitation. Simple regression was used to evaluate the discharge concentration and precipitation concentration. According to the correlation coefficient (r), the relationship between concentration and precipitation is weaker than (0.238) discharge concentration (0.699). The results further showed climate change and river water quality to be related.
