| Summary: | This study evaluates the catchment characteristics of the Pahang River Basin and its sub-basins in Pahang state, Peninsular Malaysia, utilizing GIS techniques and IFSAR-DEM data. Parameters such as stream order, shape, steepness, branching, dissection, and watershed elongation were analyzed to offer foundational insights into the basin's morphology and hydrological processes. These insights are crucial for development, management, and conservation planning. Notably, the Jelai, Lower Pahang, and Tembeling basins play a significant role in contributing runoff downstream, with dendritic patterns and moderate bifurcation ratios observed. The ongoing erosion and deposition processes, particularly in the meandering sections of the Pahang River, emphasize the dynamic nature of this landscape. These findings highlight the critical role of morphometric analysis in sustainable catchment management. Future research should further explore the spatial and relief aspects of the Pahang River basin, as well as its textural, material, and permeability characteristics, to inform and enhance watershed management strategies. © 2024, IEICES/Kyushu University.
