The examination of morphometric parameters through quantitative analysis proves highly valuable in assessing river basins, prioritizing watersheds for soil and water conservation, and natural resources management. In this study, an in-depth analysis of the Dachigam Catchment has been conducted, focusing on the quantification of various morphometric parameters. The research employs Geographic Information System (GIS) techniques to assess morphometric parameters in the micro-watersheds of the Dachigam Catchment. Linear and areal morphometric parameters were systematically derived and tabulated based on linear and shape characteristics of drainage channels, utilizing GIS and topographical maps (scale 1:50,000). The morphometric analysis conducted in the Dachigam catchment indicates that the basin has an elongated shape, suggesting that peak discharges would generally exhibit a flat profile and take time to rise. The drainage network within the basin is predominantly of the dendritic type, signifying a degree of homogeneity in texture. The slope analysis shows that the Dachigam watershed has a significant amount of steep terrain, ranging from 0 to 74.63%. The majority of the area falls within the 24 to 35% slope range. Examination of the aspect indicates that slopes oriented towards the south and southwest are the most prevalent in the basin. The watershed's mean bifurcation ratio is 1.71. This low ratio suggests that the watershed hasn't experienced significant distortion. In contrast, high bifurcation ratios exceeding 5 typically indicate distorted drainage patterns. The research illustrates how remote sensing and GIS methods can effectively analyze watershed morphometrics. These techniques offer valuable insights for planners and decision-makers involved in watershed-level planning and drainage basin management.
