Abstract:: Taiwan, an island climate with abundant annual rainfall, hillside resident is threaten by inducing landslide from the violent variation of rainfall on time and spatial distribution. This study performs the landslide model test to study the landslide mode related to slope saturation increased by high intensity rainfall. Results showed that slope sliding occurred mainly in the period of the soil closer to high saturation, oppositely, slope erosion is less affected by soil saturation. Soil permeability and rainfall intensity also affect the slope failure mode, the failure mode is mainly shallow sliding as the rainfall intensity much greater than soil permeability; the deeper sliding is mainly for the case of rainfall intensity much greater than soil permeability; last, the surface runoff erosion is usually for the rainfall intensity much lower than soil permeability.
