AB - This study presents an application of infinite slope stability method with consideration of root cohesion and spatially-distributed wetness index on the Woomyeon mountain landslide area due to torrential rain of July 27, 2011. Spatially-distributed model parameters were extracted based on digital elevation map, soil map, forest map, and then converted in to 10 m × 10 m spatial resolution data. The infinity flow direction algorithm was used to calculate the specific catchment area, which plays important role to estimate the spatially-distributed wetness index. Average daily rainfall of two automatic weather stations (Seocho and Namhyeon) were selected as rainfall input data on the slope stability assessment model under steady-state condition. Slope stability level was classified into four categories based on the factor of safety: unstable, quasi-stable, moderately-stable, stable. The simulation results showed that the slope stability was very sensitive to variation of slope steepness and most unstable areas within the study site were dominantly located in cutting-area surroundings along with the residential area and the mountaintop.
