The parameter used to assess rain-induced landslides is the safety factor of infinite slope. The influence of rainfall is taken into account by using the groundwater depth factor (m) which is relative to precipitation、porosity and plant cover. The technology of remote sensing (RS) is used to get temporal information of landslide events. The landslide susceptibility of the shitou area after the Herb typhoon (1996) and the Toraji typhoon (2001) were verified using the landslide location data. Particularly, the Toraji typhoon encroach upon the shitou area after the Chi-Chi earthquake (1999), so we must decrease the parameter used to assess rain-induced landslides. The results reveal that satisfactory consistence between the susceptibility map and the existing data on landslide location can be efficiently obtained through GIS and physical based single-variable analysis.application/pdf2027193 bytesapplication/pdfzh-TW國立臺灣大學土木工程學系暨研究所山崩潛感圖豪雨地理資訊系統溪頭landslide susceptibility zonationrainfallgroundwater depth factorGISShitoureporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/2836/1/912625Z002019.pdf
