Comparative Analysis on Methods for Evaluating Vulnerability of Debris Flow Hazard

Different criteria for evaluating vulnerability of debris flow hazard proposed by various institutes such as Korea Forest Service(KFS), Korea Institute of Geoscience and Mineral Resources(KIGAM), Ministry of Public Safety and Security (MPSS) and Korea Expressway Corporation (KEC) were reviewed and discussed. Assessment of debris flow hazard for natural slopes around land for house development was carried out on the basis of the report about results of performing in-situ survey. Results of evaluating vulnerability of debris flow hazard by using these methods were compared to each other to discuss appropriateness of their evaluation and to recommend improvement.
