研究期間：10108~10207;To meet the goal of the main project, this sub-project plan to take some famous large-scale landslide cases of Taiwan as the material to study their geomorphology and geology, and to review landslide properties and process for each case, through remote sensing image interpretation, geomorphic analysis and detailed field geological survey. This sub-project will also perform analysis on multi-temporal landslide inventories at the drainage basin where a famous landslide is located, so that characteristic marks of landslides could be identified. The scaling law which controls the landslide size distribution could also be found. Does there exist potential catastrophic landslide in the drainage basin will also be discussed. The main project is a three-year plan, and this is the third year plan of the present sub-project. The study area in this second year will concentrated at the Sunpingshi drainage basin and the Hesheshi drainage basin; the famous Tuchang landslide and the Hesheshi landslides will be reviewed and studied with new data. Review of large-scale landslides in Taiwan will be finished in three years. Comparison with world cases will also be included in this study. The optimal goal of this sub-project is to established large-scale landslide classification with discussion of landform evolution in an active orogen like in Taiwan.
