  • Microbiological water quality of the Nišava River

    Microorganisms are the ideal indicators of the organic pollution of the surface waters because of their ability to promptly respond to environmental changes. Due to poor economic situation and lack of law implementation, most wastewaters in Serbia are released directly into a surface water recipient without any, or a limited, treatment. This practice has created numerous highly polluted ...

  • The impact of farming on river banks on water quality of the rivers

    Abstract A study was carried out in a strip of a river in the dry and rainy seasons to assess the effect of farming along river banks on the quality of water in rivers. The results showed that there was an increase in the concentration of nitrate in the water downstream in both the rainy and dry seasons. In both rainy and dry seasons, the total nitrogen in the soil was highest (p ...

  • Water Quality Parameters Along Rivers

    Water samples have been collected from a part of Surma River along different points and analyzed for various water quality parameters during dry and monsoon periods. Effects of industrial wastes, municipal sewage, and agricultural runoff on river water quality have been investigated. The study was conducted within the Chattak to Sunamganj portion of Surma River, which is significant due to the ...

  • The influence of lagoon on neighboring rivers by water and sediment quality

    Canonical discriminant analysis (CDA) was applied in order to distinguish the water-quality and the sediment-quality parameters from neighboring rivers, and to recognize similarities of water and sediment properties between a lagoon and neighboring rivers. Two set of constructed discriminant functions showed a marked contribution to most of the discriminant variables. In water, the significant ...

  • Continuous water quality monitoring on Kolubara River

    The first automated station for water quality monitoring located in Beli Brod on the Kolubara river has launched on July 2008. The station was established as the result of RHMSS participation in Twinning project financed by EU, where RHMSS was entrusted with the Component 2 of this project. Installed equipment continually records values of water level, temperature, pH, electroconductivity and ...

  • Assessment of River Water Quality in Northwestern Greece

    The effect of land use patterns on river water quality was studied in three different river basins located in Epirus, Northwestern Greece. Studies were conducted from October 2000 to {September} 2001. During this period, the parameters chemical oxygen demand (COD), biological oxygen demand (BOD), NO2–, NO3–, NH4+ and PO43– were measured, employing standard methods of analysis. The results were ...

  • Review of spatial variations in water quality in the Gediz River

    The Gediz River is one of the most important and main water source for the Gediz Basin of the Aegean region and Turkey. In this study, 18 water samples were collected from the source to the end of the river. Change in water quality, some trace elements and heavy metal contents of the Gediz River were determined. Analysis of the Fe, Cu, Mn, Zn, Pb, Cr, Co, Cd and Ni showed that the quantity of Fe ...

  • A hydrodynamic water quality model for propagation of pollutants in rivers

    Numerical modelling can be a useful tool to assess a receiving water body's quality state. Indeed, the use of mathematical models in river water quality management has become a common practice to show the cause-effect relationship between emissions and water body quality and to design as well as assess the effectiveness of mitigation measures. In the present study, a hydrodynamic river water ...

  • Water quality assessment of a polluted urban river

    Urban rivers in Latin America are heavily impacted by human activities that affect their functions and services. This paper shows the results of a water quality assessment for the Reconquista River, the second most polluted urban river in Argentina. They allowed the identification of the main processes of transport of pollutants and the prioritisation of different areas of the basin for ...

Aguas Danone de Argentina is part of the Danone Group, world leader in the food and beverage industry, with products reaching 120 countries on 5 continents. The bottling plant located in ...

  • Impact of barrages on downstream air entrained in water and on upstream river water quality

    This research studies the effect of barrages on upstream river water quality and on its self-assimilative. Also, the impact of barrages on upstream water temperature profile is studied. The amount of entrained air in water at river downstream side as a result of barrage existence is also studied. Constructing barrages in river reaches will alter its hydraulics and thus its water quality and ...

  • A system dynamics-based conflict resolution model for river water quality management

    Conflict is a disagreement among individuals or groups that differ in attitudes, beliefs, values or needs. Contemporary water resources management is a combined process of sharing water and resolving conflicts among decision makers and stakeholders. Stakeholders in this context refer to individuals, organizations, or institutions that have stakes in the outcome of decision related to water or ...

  • Water quality assessment of Yamuna River in Delhi region using index mapping

    Water quality indices (WQI) were introduced with the aim of reducing great amount of parameters into a simpler expression and enabling easy interpretation of monitoring data. In this study, an attempt has been made to devise a methodology to integrate the WQI with geographic information system (GIS) for an effective interpretation of the quality status of the river. River Yamuna in Delhi has been ...

  • Heterogeneity of water quality in Huai River, China by using bio-monitoring data

    A new approach by combining bioindicators (BiI) and biotic indices (BIs) for evaluating water quality is presented in this paper. It is then applied to the Huai River Basin (HRB), China, which is well-known globally for its heavy anthropogenic influences. Results indicate that the spatial distribution of BI-indicated water quality has roughly the same pattern as that shown by BiI, but the ...

  • Error analysis for river water quality prediction using back propagation modelling

    The purpose of this research is to describe the errors of Back Propagation (BP) technique that could be applied in river water quality prediction. ANN was trained by using the upriver data to forecast the downriver quality in two approaches of long-distance forecasting and short-distance forecasting respectively. It showed that the predicted results from short-distance approach were more accurate ...

  • Changes in the water quantity and quality of the Euphrates river are associated with natural aspects of the landscape

    It has been argued that dam construction and irrigation projects in Turkey and Syria would diminish the flow of the Euphrates River and increase salinity levels. However, previous studies have not systematically defined the baseline changes in the quantity and quality of the river water. In this study, we associate variations in flow quantity and quality of water with natural aspects. We ...
