Abstract: Kunigal Taluk is located in the southeastern corner of Tumkur district in Karnataka state. The taluk covers an area of 981.55 Sq.km, and average rainfall of 600-817mm. Kunigal Taluk is bounded by Latitude N 120 44’ 38.74’’ to130 8 ’ 1.16’’ and longitude E 760 49’ 43’’ to 770 9 ’ 57’’. The main part of the area is covered under Survey of India (SOI) Toposheet numbers 57C/16, 57G/4, 57D/13, 57H/1 and 57H/2 (Scale 1:50,000). Kunigal Taluk falls in the southern dry agro-climatic zone. The semiarid region and frequently facing water scarcity as well as quality problems. The major sources of employment are agriculture, horticulture and animal husbandry, engaging almost 80% of the workforce for the livelihood. Water samples are collected from 98 stations during pre-monsoon and 98 locations during post-monsoon of the year 2014, and were subjected to analysis for chemical characteristics. The type of water that predominates in the study area is Ca-Mg-HCO3 type during post-monsoon seasons of the year 2014, based on hydro-chemical contents. Besides, suitability of water for irrigation is evaluated based on sodium adsorption ratio, residual sodium carbonate, sodium percent, salinity hazard and USSL diagram.
