“…The technique includes smooth particle hydrodynamics (SPH), the material point method (MPM), the particle finite-element method (PFEM), the finiteelement method with Lagrangian integration points (FEMLIP), and the element-free Galerkin (EFG) method. In particular, many researchers have applied the material point method for the simulation of rainfall-induced landslides in recent decades (Yerro et al, 2015;Bandara et al, 2016;Soga et al, 2016;Wang et al, 2018;Lee et al, 2019a;Lee et al, 2019b;Ceccato et al, 2019;Cuomo et al, 2019;Lei et al, 2020;Liu et al, 2020;Martinelli et al, 2020;Liu and Wang, 2021;Nguyen et al, 2021).…”

“…Yerro et al (2015) attempted to model infiltration in an unsaturated brittle material, where a coupled 3phase 1-point MPM formulation associated with a suctiondependent elastoplastic Mohr-Coulomb model was proposed; the well-known van Genuchten model was applied, and the rainfall boundary conditions only considered the type of pore water pressure. Later, different pseudo-3-phase 1-point MPM formulations were proposed by Bandara et al (2016), Wang et al (2018), Lee et al (2019b), Martinelli et al (2020), andCeccato et al (2020). Bandara et al (2016) derived a coupled pseudo-3phase 1-point MPM formulation and obtained the infiltration rate of rainfall boundary based on Darcy's velocity.…”

“…In order to improve the previous limitations, this study proposed a numerical model, which implemented a pseudo-3-phase 1-point MPM formulation, to simulate the lab-scale rainfall-induced slope failure. This study applied the rainfall boundary condition algorithm following Martinelli et al (2020) to validate the van Genuchten model. Therefore, the deformation characteristics influenced by the rainfall conditions could be completely investigated from the pre-failure stage to the postfailure stage.…”

The kinematic behavior of rainfall-induced landslides from the pre-failure stage to post-failure stage contains important information for risk assessment and management. Because a complex relationship exists between rainfall conditions, pore water pressure, soil strength, and movement rates, a numerical model is the most efficient way to investigate the behavior of rainfall-induced landslides. In this study, the material point method (MPM) is used to investigate the dynamic behavior of landslides. First, the rainfall boundary conditions are extensively verified by comparing 1-D consolidation tests against other numerical solutions. Then, a numerical model is used to simulate a lab-scale rainfall-induced slope failure. A parametric study shows the influence of rainfall intensity on pore water pressure development, failure triggering time, surface displacement, and velocity. The use of the MPM provides a clear understanding in the failure mechanism and post-failure behavior of a rainfall-induced landslide.

Debris avalanches often originate along steep unsaturated slopes and have catastrophic consequences. However, their forecast and mitigation still pose relevant scientific challenges. This is also due to the variety of mechanisms observed near high sub-vertical bedrock outcrops, such as the impact loading of soil failed upslope the outcrop, the build-up of pore water pressures in the inception zone, and the bed entrainment along the landslide propagation path. At the University of Salerno, an experimental and numerical investigation campaign started some years ago to explore the feasibility of using long-root grass to mitigate or even inhibit the inception of debris avalanches. Previous laboratory results were achieved through two twin 2-m-long columns (one bare, one vegetated), where the change in soil retention curve and soil mechanical response was assessed. As follow-up, an experimental field setup was installed in 2020 first, and in an improved configuration in 2021. Here, three different species of long-root grass were grown. In situ soil suction and water content measurements were periodically collected in the vegetated and in the original soils. In both cases, soil specimens were also collected, and laboratory geotechnical tests were performed to individuate the changes in both the water retention and strength response. Increased values of soil suction and shear strength were outlined, despite some differences, for all the grown species compared to the original soil. Using these novel experimental data, advanced large-deformation stress–strain hydro-mechanically coupled analyses were recently performed through a material point method (MPM) approach. The original slope conditions were compared to various slope configurations engineered via long-root grass. The benefits and the open issues related to this novel green technology for landslide mitigation are discussed. Some insights are outlined for the possible reduction of the soil volumes mobilized inside the inception zone of debris avalanches.
