SEASONAL VARIATION IN THE PHYSICO-CHEMICAL CHARACTERISTICS ALONG THE UPSTREAM OF TUNGABHADRA RIVER, WESTERN GHATS, INDIA
The present study was undertaken to know the variation in different seasons in response to physico-chemical properties of Tungabhadra river, Western Ghats, India. The study was carried out over a period of one year from December 2009 to December 2010. The study of physical parameters namely air temperature, water temperature, salinity, conductivity, dissolved solids, suspended solids, total solids and chemical parameters such as pH, total hardness, dissolved oxygen, total alkalinity, chloride, calcium and magnesium showed noticeable seasonal variations, which may be attributed to the local climatic conditions and water exchange mechanisms. Analysis of water quality parameters indicated that water was free from any sort of contamination since it is an unpolluted area.
