The quantitative measurement and analysis of the physical parameters of a drainage basin or catchment area is known as basin morphometry. Relief aspects of basin morphometry focus on the elevation and vertical differences within the basin. Relief is a crucial factor in understanding the landscape's topographic complexity and has significant implications for various natural processes and human activities. The Ratnagiri district's Saptlingi Basin in the Sangmeshwar Taluka has been selected as the study region for the current research. The primary objective of the present research is to investigate the relief morphometry of the Saptlingi basin using ArcGIS and ASTER GDEM data. The study reveals that the study region has the typical type of relative relief
