Description :
This paper explores the hypothesised influence of progressive regolith stripping and redeposition on slope failure using a recently developed process-based model. This model couples dynamic hydrology with slope stability analysis, allowing to relax the previous assumption concerning the role of pore water pressures on slope stability. The model is then used to investigate both changing triggering thresholds as well as changing mechanisms for slope instability in New Zealand hill country.
