The Kuranji watershed is one of the largest watersheds in the city of Padang. Several landslides and floods have been reported in this area. Many factors cause landslides, both natural and non-natural factors. One of the natural factors that cause landslides is the topography/slope condition. The sloping/steep topography in the downstream area of the Kuranji watershed causes a high potential for landslides in this area. Landslides occur due to balance disturbances that cause the movement of soil and rock masses from a higher place to a lower place. Therefore, it is necessary to analyze slope stability to determine the effect of slope conditions on the potential for landslides. In this study, an analysis of the potential for slopes stability was carried out using the Ordinary Method of Slices. The analysis is carried out by making different slopes so that the value of the safety factor will be obtained from each slope. The slope variation used in this study is the ratio of height to slope width of 1:5, 1:4, 1:3, 1:2, 1:1, 1:0.5, 1:0.25. The results showed that the smaller the slope and the height of the slope, the more stable the slope will be, on the contrary, the larger the slope, the more unstable the slope. This can be assessed from the value safety factor (SF) of slope stability which is obtained from the calculation, which is getting smaller as the slope and height of the slope decrease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
