AB - Because of localized torrential downpour, typhoon and other factors by the changes in climate, there have been slope failures, landslides and debris flows, which caused huge economic loss and human victims. Especially, because the most area of Gangwon province is composed of the steep sope mountains, the damages by the debris flow or landsliding are more frequent and frequency has been inreeased. To analyze the cause of such soil disaster, research using GIS and remote sensing is in process recently. In this study, to investigate the characteristic of the region where debris flow occurs, we analyzed the image before and after the occurrence of debris flow in Mt.Gari, Inje-Gun, Gangwon-do. By this analyzing, we extracted disaster zone and digitized it. Using digital map, we also formed DEM, extracted targeted basin, collected and analyzed spatial data to conduct hydrological and geopolitical analysis by debris flow-occurrencing areas. We conducted correlation analysis considering slope and distance from river as well. As a result, the mean slope of initiation was 29°, the mean slope of transport was 23° and the mean slope of deposition was 12°among the characteristics causing debris flow. Analysis about Butter Zone which composed along river valleys showed that 79 of 114 points where debris flow and landslide occur are in the Buffer Zone which includes river.
