Abstract In this research we analyzed the morphometric parameter of Palar River basin by using satellite data from open sources for monitoring drainage network. covers 1972.27 sq.km areas with elevation 226.9 m as highest and 38.01 lowest above mean sea level. it detected that having 5th order stream density 0.40 km/km 2 pattern dendritic to rectangular. We also draw aspect map, relief map slope area digital model (DEM) 30 resolution. employed spectral indices like normalized difference vegetation index (NDVI), water (NDWI), soil adjusted (SAVI) vegetation, characteristics area. found there are major changes in land use/land cover bodies during these periods 15 years. Highly positive correlation show between indices. groundwater level year 2005 2020 used validation study. This work is very useful developing solutions dealing different types drought management extraction plans.
