According to recent meterological disasters, social awareness for safety of infrastructure is heightened by increasing natural disasters such as Fukushima accident, landslide of Umyeon mountain. Also scale of landslide is increased in Korea but safety review of dam is insufficient. In this study, we reviewed data(reservoir capacity, type of dam, danger map of korea forest service, satellite pictures, geologic map, etc.) and conducted site investigation whose the area is the most dangerous. Based on the results, we choose the most dangerous dam and analysis site close examination, slope stability analysis, scale of debris flow, etc. As a result, we will conduct measures establish on reinforcement and final evaluation of landslide's hazard.
