Abstract

The objective of this study is to develop the evaluation method of the slope failure using not only satellite multi-spectral data and geographical data but also secondary generated data for planning highway route in shirasu area.<br>As for the feature of the erosive area, as a Shirasu plateau, mudflow occurring simultaneously with slope failure brings about disaster frequently. In this study, using the slope stability evaluation map which was made from satellite mulli-spectral data and geographical data, the evaluation procedure making a comparison between the distributions of extracted pixels in the catchment areas calculated from digital terrain model (DTM) was proposed. It was shown that the proposed procedure was very useful for pre-evaluation of highway route in shirasu area.
