Water quality analysis of Bhadravathi taluk using GIS – a case study

The paper presents a case study on the water quality analysis carried out at the Bhadravathi Taluk, Karnataka, India. Twelve physico-chemical parameters were considered in the analysis. Geographic information system (GIS) is used to represent the spatial distribution of the parameters and raster maps were created. The analysis was carried for pre-monsoon and post-monsoon seasons. The water quality index indicated that most of the sampling locations come under good category indicating the suitability of water for human use. Due to the industrialization and agricultural disposal some of the sampling locations became unfit.
