The modeling of transient flow in unsaturated soils for rainfall-induced landslides using a novel spacetime collocation method is presented.
A numerical solution obtained in the spacetime coordinate system is approximated by superpositioning Trefftz basis functions satisfying the linearized Richards equation for collocation points on the spacetime domain boundary.
The Gardner exponential model is adopted to derive the linearized Richards equation to describe the soil-water characteristic curve in unsaturated soils.
To deal with the rainfall-induced landslides, the infinite slope stability analysis coupled with the proposed meshless method with the consideration of the fluctuation of time-dependent matric suction is developed.
The proposed method is validated for several test problems.
Application examples of transient modeling of flow for rainfall-induced landslides in homogenous unsaturated soils are also conducted.
Numerical results demonstrate that the proposed method is highly accurate to deal with transient flow in unsaturated soils for rainfall-induced landslides.
In addition, it is found that the numerical method using the Richards equation with the Gardner model may provide a promising solution for different soil textures.
