These huge sediment deposits located on the upstream creek valley or transporting to downstream area would largely threaten people who live in downstream area. In order to mitigate the scale and threatening of debris-flow disaster, this project collected related literature about debris flow and analyzed the disaster sources of Typhoon Toraji at Hsitou. Moreover, the experimental content and its procedure are also planned here.application/pdf247524 bytesapplication/pdfzh-TW國立臺灣大學水工試驗所土石流溪頭發生機制Debris flowHsitouMechanism of occurrencereporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/9905/1/902625Z002017.pdf
