The Son River Basin in Sonbhadra District, Uttar Pradesh, has a important role to play in the region's environmental dynamics and hydrology. The present work presents a comprehensive analysis of different parameters of the morphometry of the Son River Basin, employing advanced geo-spatial techniques. In the present paper, digital elevation model was processed to delineate the basin's boundaries and extract various parameters of morphometry such as stream order, stream length, drainage density, basin relief, contour, slope-aspect, and watershed shape. The analysis provides important observation regarding the characteristics of morphometry of Son river basin and aids in understanding its geomorphological evolution. According to the study, the Son basin in the Sonbhadra region has a perimeter of 438.50 km and a surface area of 3214 km2. The basin is 896.15 km long and contains six orders of stream. The basin's drainage density is 0.7 km/km2 while stream frequency is 0.36 km2, relief ratio is 9.38, mean bifurcation ratio is 4.04. Other parameters are also processed and calculated using suitable techniques.
