Plate tectonic actions causing steep slopes and complex geological settings, and heavy rainfall induced by seasonal typhoons, dimmed Taiwan with high potential of debris flows hazards. Soil and Water Conservation Bureau, Council of Agriculture, Executive Yuan, has launched the investigations for streams with potential debris flow since 1991. In 2003, the SWCB commissioned National Taiwan University to pursue follow-up investigations and to monitor the evolutions of potential debris flow. The work includes debris flow stream site investigation, potential area identification, rating and evaluation, and mapping, database establishment of affected area and evaluation of potential hazardous villages, and establishing query system for the potential data, for the 1420 potential debris flows in Taiwan. “Researching and planning for update and feedback system of the debris flow potential database” project in 2005, and “The debris flow potential database management and update” project in 2006 and 2007 all aimed at annual maintenance of debris flow potential database. The draft of “The regulation of making the debris flow potential database public”, which was compiled in 2007, advises overall renewal of the potential debris flow database every five years. It’s already 5 years since 2002. In order to maintain correctness and reflect the field conditions and potential ranking, it is necessary to update and revise the debris flow potential database; meanwhile, it is also important to re-evaluate potential and management priorities in order to provide vital information for hazard management. The objective of this project is to update the database of the debris flow potential, and to amend the update contents in the database for more effective using of the essential information; to assist SWCB in establishing legislation by referencing disaster management model of other countries; to enhance the local government’s management and executive ability for future application of the database. In addition, this project re-evaluates the rating of debris flow potential and management priorities. The result would provide effective and essential information system for debris flow hazard mitigation.土石流潛勢溪流土石流潛勢溪流資料庫土石流災害潛勢資料公開辦法作業要點法制化程序potential debris flow torrentdebris flow potential databasethe regulation of making the debris flow potential database publiclegislation.
