| Abstract: | Monitoring of land use and land cover change (LULC) is essential for water conservation and management. In this study, an attempt has been made to understand the impact of LULC change on groundwater quality. In the present study LULC map of the study area prepared using satellite image of year 1999 and 2016 which are visually interpreted with help of ERDAS IMAGINE and ArcGIS software. In this study different image interpretation elements like tone, texture, size, pattern and association were used and verified with field check and total eight LULC classes were recognized such as settlement, road, cultivation, industry, drainage, lake, open land and vegetation. Comparison of LULC of year 1999 and year 2016 indicates that the settlement (net increases 16.2%), road (net increases 0.8%), open land (net increases 14.8%) and industry (net increases 3.1%) area has expanded. In the study area groundwater pollution is mainly associated with LULC change and as well as poor waste management practices. Obtained result has been validated with nitrate concentration and found 73.33% accuracy reflecting that, applied techniques has produced significantly reliable results. |
