Simulation of Rainfall-Induced Landslide of the Vegetated Slope
Abstract Soil bioengineering methods offer an efficient and eco-friendly solution for slope stabilisation. These measures are especially effective in protection against shallow, rainfall-induced landslides, in which the potential slip surface crosses root zones. Vegetation contributes to the enhancement of the slope stability in several ways, but there are two factors which are the most significant, namely, mechanical root reinforcement and evapotranspiration. The model proposed in this paper allows simulation of rainfall-induced landslides of vegetated slopes, taking into account both factors. The model is tested performing the numerical example, based on the case study. Stability of the bare and vegetated slope is investigated and obtained results are compared and analysed. Rapid accumulation of displacements indicates a moment of failure. Stability enhancement due to the vegetation is defined in reference to the stability of a non-vegetated slope, as the delay of the occurrence of a rainfall-induced landslide.
