Abstract

The purpose of this study is to clear the relationship between rainfall factors and geomorphological factors to predict slope failure and prevent landslide disasters during heavy rainfall. In this study, risk of slope failure caused by geomorphological factors is evaluated statistically using existing inspection records for steep slopes through the application of Quantification Theory Type 2. Moreover, rainfall factors are analyzed to determine the critical rainfall line. Conventional liner Critical Line and Soil Water Index calculated by Tank Model are under consideration, in this research. This paper shows that high risk areas are prone to landslides with little rain. The results of these analyses will specify and predict areas prone to collapse for warning and evacuation procedures.
