An Estimation of Reach Distance for Slope Failure Debris

Abstract

This paper concerns an estimation of reach distance of debris flow by slope failures due to rainfall. The analyze is conducted by a quantification theory which bases on the inspection procedure of difference between the categorized adjacent average values. The main items governing reach distance of debris are shown as failure height, longitudinal slope profile and accumulative rainf all amount. The multiple correlation coefficient is 0.8470, and 70 % of the reach distance variation for all slope failures can be explained by the used items in this study.
