On the Investigation and Analysis of Slope Movements Based on High-Revolution Terrain Data

The processes and affected area of mass movements triggered by rainfalls and earthquakes are vitalfor hazard mitigation and land managent. In this three-year-span proposal (2017-2020), we will explorethe initiation, transport and deposition processes of massive landslides in different geological settingssuch as in Pingguan, Houyenshan and Nanshru watersheds in New Taipei, Miali and Kaoshungcounties, respectively. The on-site monitoring system of gravelly debris flows will be carried out toobtain the runout distance as a function of the driving rainfall. The geomorphic parameters controllinglandslides and debris flows will be examined based on case studies. Throughout the integration of casestudies, analysis and on-site monitoring system, the result of this study will be benefical for the furtherunderstanding of slope movements and the consequent affected area.
