One of the main rivers in Peninsular India is the Cauvery River. It faces a lot of anthropogenic influences due to its prominence in culture and a dense population along its banks. In this analysis, surface water samples were collected from 50 river stations and their tributaries and analysed in February 2009 and October 2009 for their physicochemical characteristics in order to understand the causes of water contamination and the evolution of water quality. The findings show a considerable difference in the water quality parameters of the river, which was also affected by the water quality of its tributaries. In the flow, which was due to catchment characteristics and point or non-point sources of contamination, seasonal variations were observed. It was found that the Pearson correlation used to assess the correlation between the parameters of water quality was strongly correlated. In order to obtain better information about the quality of surface water, the regression equations built to estimate the parameters responsible for water quality variations are found to be useful for evaluating missing data.
