Potohar region in the Himalayan foothills is one of the mountainous places in Pakistan prone to landslides. This study focuses on the identification and delineation of likely landslide danger zones using a multi-criteria approach in a GIS and remote sensing environment based on the analysis of various morphometric data. The hydro geomorphological properties of the research area can be depicted using these morphometric metrics. Based on this, all of the morphometric data are combined to create a landslide susceptibility map, which has been shown to be beneficial in predicting potential landslide susceptibility zones. The basin area of this investigation is only 6545 square kilometers. According to the findings of this study, the high landslide sensitive zone is located mostly in the upper portion of the basin, and in a dispersed way around the very high zone in the upper middle and lower middle parts of the basin. This zone encompasses around 27% of the total area. The basin's intermediate landslide susceptibility zone accounts for 17% of its total area. Other morphometric indicators have a significantly lower value than very high and high LSZ. As a result, in terms of vulnerability, this zone is classified as moderate. The low zone covers 38% of the basin. . The study in this basin revealed the following fact: (1) A very high landslide susceptibility zone is associated with locations that are vulnerable due to both drainage and topography conditions. (2) Morphometric indicators imply that high drainage density and steep rock surface are the primary causes of landslides in this region, which are almost definitely induced by rainfall during monsoon months. (3) The zone of extremely high landslide susceptibility is associated with heavy runoff, seasonally saturated bedrock, and high intensity of erosion, whereas the zone of low susceptibility is related with excellent slope stability and moderate intensity of erosion.
