산사태 위험지도와 연계된 도심지 토사재해 취약성 평가: 부산광역시 적용

Abstract

In this study, an urban mud and debris flow disaster vulnerability assessment model based on landslide risk map being used by Korea forest service is proposed. In order to examine the vulnerability of urban areas, the assessment model is configured to reflect the exposure intensity, sensitivity level, and the ability to adapt to landslides. The proposed model consists of one zoning and three detailed indicators which are a buffer zone derived by landslide hazard map, an indicator of personal injury, an indicator to cause secondary damage, and an indicator of disaster preparedness and response capability. Three detailed indicators have six, five, and six agencyrelated variables, respectively. The weights among detailed indicators and those among surrogates that make up each detailed indicator are setting by the AHP survey technique. The developed model is applied to Busan, and the vulnerability of urban mud and debris flow disaster is evaluated.
