Research Abstract

We need to make clear parameters controlling slope stability to predict occurrence of landslides in large mountainous catchments. New non-dimensional representations for the slope stability were obtained by the normalization of the safety factor equation as well as equations representing groundwater infiltration. The landslide model developed in our study could explain characteristics of landslides, including timing of initiation and depth of slide surface.
