It is observed during the study that many dyeing, sugar and paper units discharged their untreated effluent into the river Cauvery in this criminately without any treatment. The river water samples and ground water samples and soil sample collected in the study area reveals that high degree of the pollution cost by untreated effluent of heavy metal analysis from the river water and ground water and soil. So that industries major culprit in damaging the river water, ground water and soil used for the agricultural purpose. The increased loading of toxic effluent day by day due to the toxic effluent of surface water, ground water and soil. The total pollution due to industrial effluent causes the great damage to the environmental pollution of river Cauvery at pallipalayam in Namakkal district.

    Published by : International Journal of Engineering Research & Technology (IJERT) http://www.ijert.org ISSN: 2278-0181 Vol. 6 Issue 11, November - 2017 Time Series Analysis for Water Inflow Sara Kutty T K* Hanumanthappa M Research Scholar, Computer Applications Department, Rayalaseema University Bangalore University Kurnool, India Bangalore, India Abstract—The main sources of water are natural sources like This paper aims at a time series analysis of Cauvery water in rainwater, oceans, rivers, lakes, streams, ponds, springs etc., and Karnataka. In particular time series of data is plotted to find man-made sources like dams, wells, tube wells, hand-pumps, any possible trend. Using ARIMA model future water inflows canals, etc. Agriculture and plantation depends heavily on water is plotted. We would like to use the data for water and its source is rainfall. Mathematical models are required to management analysis and for model based statistical inference predict future water demand and climate changes. Time series are valuable sources of information that can be consulted for the of environmental systems that account for the need of using characterization of variables in several areas of knowledge. It is prior information, input and model structure uncertainty. In basically a measurement of data taken in chronological order order to analyze the water inflow the average wet weather within a certain time. In hydrology, such series are employed in flow can be estimated from water flow data. Water inflow is water systems management as tools for the hydrological cycle defined as the water other than sanitary wastewater that enters understanding. The purpose of most water quality and stream a sewer system from sources such as roof leaders, flow studies is to point out the information and necessary cellar/foundation drains, yard drains, area drains, drains etc.

    Study on the Quality of Water in Some Streams of Cauvery River

College, Bangalore. Visveshwaraya Technological University, Belgaum, [email protected] Received 30 October 2007; Accepted 20 December 2007 Abstract : The quality of water in four streams of Cauvery River in Mandya District, where many small scale sugar and brewery distilleries are located, was analysed. Sampling was carried out from four streams designated as station 1 (upstream of effluent discharge point), station 2 (effluent discharge point) and station 3 (downstream of effluent discharge) station 4 (fresh water stream) to assess the impact of effluent on the water quality. The river water composition is increasingly dominated by Na and Cl in the downstream region of the river, indicating the influence of airborne salts with oceanic affinities. Significant spatial variation was observed in water level, transparency, turbidity, depth, dissolved oxygen, colour, biochemical oxygen demand, nitrate, nitrite and total hydrocarbon among the physiochemical parameters of the study stations. A posteriori test revealed that station 2 & 3 were the cause of the significant difference. The dissolved oxygen level in stations 2 & 3 was lower than 5.0mg/L, which is recommended minimum allowable limit for aquatic life. About 7 rotifer species in large amount recorded in this study were encountered in station 1, 7 in station 2 & 3 while 12 species in station 4.

[email protected] Received 29 March 2008; Accepted 20 May 2008 Abstract: Analysis of water, plankton, fish and sediment reveals that the Cauvery River water in the downstream is contaminated by certain heavy metals. Water samples have high carbonate hardness. Concentrations of all elements and ions increase in the downstream. Main ions are in the following order: Na > HCO 3 >Mg > K > Ca> Cl > SO 4. Heavy metal concentration in water was Cr >Cu ≈ Mn > Co > Ni > Pb > Zn, in fish muscles Cr > Mn > Cu > Ni > Co > Pb ≈ Zn, in phytoplanktens Co > Zn > Pb > Mn > Cr and in the sediments the heavy metal concentration was Co > Cr > Ni ≈ Cu > Mn > Zn > Pb. Although, the quality of Cauvery River may be classified as very good based on the salt and sodium for irrigation, Zn, Pb and Cr concentration exceeded the upper limit of standards. Metal concentrations in the downstream indicate an increase in the pollution load due to movement of fertilizers, agricultural ashes, industrial effluents and anthropogenic wastes. An immediate attention from the concerned authorities is required in order to protect the river from further pollution. Introduction The natural elements which cause water pollution is gases, soil, minerals, humus materials, waste created by animals and other living organisms present in water 1,2 .
