This study performs a hypsometric analysis of the Pahang River Basin and its sub basins to as sessg eomorphological and hydrological characteristics. Utilizing 30-metre resolution of Inte rferometric Synthetic Aperture Radar (IFSAR), the Digital Elevation Models (DEMs), we generated hypsometric curves and calculated integrals, revealing significant landscape variations. The basin primarily exhibits a mature landscape with concave curves, indicating balanced erosion and deposition, while some sub basins show convex curves, suggesting youthful topography and active erosion. These findings highlight spatial variability in hydrological processes, impacting runoff generation and sediment transport. Understanding these hypsometric properties is crucial for effective water resource management and supports targeted conservation strategies to mitigate erosion and enhance watershed stability. © 2024, IEICES/Kyushu University.
