Abstract
Vermont has recently faced severe roadway damage due to climate-induced heavy rainfall, which has triggered uphill landslides and debris flows. The susceptibility of debris flows is influenced by slope angles, slope materials, and rainfall intensity. Simple Finite Element Method is used for slope stability analysis along with verification using data from some existing failure sites. We have implemented a GIS (Geographic Information System) based approach to map the probability of debris flow occurrence linked to empirical rainfall thresholds. Digital Elevation Model (DEM) is used to monitor spatial movement of slopes before and after the hazard.
