This Project Grant award, funded by the National Science Foundation (NSF) Engineering program (CFDA 47.041), supports research at Virginia Polytechnic Institute & State University (Virginia Tech) to advance the understanding of rainfall-triggered landslides and their consequences, considering vegetation effects and climate change. The $570,960 award, effective March 1, 2024 through February 28, 2029, aims to: (1) develop numerical analysis methods to incorporate the hydromechanical effects of vegetation on landslide initiation and kinematics; (2) provide new physical insights on how different root systems and soil characteristics impact landslide instability; and (3) assess landslide failure probabilities and runout distances using mechanistic machine learning models accounting for precipitation, vegetation, and soil uncertainties. The resulting knowledge is expected to transform approaches to slope stability and risk assessment, with applications to other hazards like wildfires and dam failures. The project also includes integrated educational and outreach plans to disseminate findings, increase STEM engagement, and raise awareness of landslide hazards in local communities.
