This study aims to develop a feasibility procedure of incorporating debris flow geological sensitive area into current debris flow potential torrents, that utilized information from Environmental-Geological Database of slope-land by Central Geological Survey and building distribution to identified possible potential debris flow torrents. Review 50-meter buffer zone of debris flow geological sensitive area is more than a building, and excluding the debris flow potential torrents by Soil and Water Conservation Bureau. Through spatial analysis and investigation of debris flow geological sensitive areas were extracted, overlaying it with possible exposures and identified possible potential debris flow torrents for future applications. The results could be utilized in improving debris flow hazard mitigation, hazard reduction and debris flow risk management in the future.
