Abstract

In civil engineering, while the impact of vegetation on bank slope stability is well-recognized, its role in managing slope instability during rainfall remains underexplored. In this study, a numerical model considering bank slope instability control by vegetation during rainfall is developed. The results show that the vegetation root system improves slope stability by enhancing soil cohesion and regulating seepage processes. Woody plants are more effective for slope protection in the early stage of rainfall, while herbaceous plants are more significant in later stage. Planting on the top of bank slope is more effective during the early stages of rainfall, whereas planting on the slope surface provides better slope stability during whole rainfall. Vegetated slope is the most effective at low to moderate intensity rainfall, but its stability effect becomes less obvious under extreme rainfall.
