Abstract

The topography of slope lands at Taitung County in the eastern Taiwan is quite steep combined with fragile geological structure. Chihpen and Taimali watersheds located at Taitung County were selected as study areas. In this research, mechanism, behavior, and scale of the sediment disasters are analyzed to rule out their interaction of the factors mentioned above and the extent of the debris flow. In this study, applications of global positioning systems (GPS) would be used to preciously locate site position. Geographic information systems (GIS) and remote sensing (RS) techniques are integrated and used to establish the sediment related disaster database system based on mathematic methods. 522 engineering related data were investigated from the field and analyzed by using the Multiple Linear Regression Analysis. Finally, GPS/GIS/RS integrated with the digital data was used to establish risk assessment model which can be utilized as an indication of sediment disaster occurrence. All results established by this study can help Taitung Country set up its own disaster prevention system and keep well development of rural and city in the eastern Taiwan.
