Dakshina Pinakini river basin is a sub basin of River Kaveri, located in the north eastern corner of Karnataka state. The study area is spreads over an area of 2185 sq. km falling within the semi-arid region and frequently facing water scarcity as well as quality problems. To analyses the water quality parameters, 184 samples are collected from different locations during pre-monsoon and post-monsoon period. The type of water that predominates in the study area is Ca-Mg-HCO3 type both in pre- and post-monsoon seasons based on hydro-chemical facies. Besides, suitability of water for domestic and irrigation purposes are evaluated based on sodium adsorption ratio, residual sodium carbonate, sodium percent, salinity hazard and USSL diagram.
