Description: We implemented, by means of analogue laboratory modelling, the key processes of the feedback among erosion and landslides, isostatic response and lithospheric flexure, to address how these lead to landsliding. The processes involved have different response times and characteristic length-scales and/or threshold behaviours and are suitable to the investigation in scaled analogue experiment, which aptly capture the behaviour of the natural prototype. These processes have been simulated using sand, to simulate mountain slopes, erosion and landslides, and viscous solids, e.g., syrup and silicone, to simulate the underlying lithosphere and mantle. This approach combines established techniques, such as laboratory fluid-filled tanks reproducing deformation and restoring force of the Earth’s mantle, and silicone to reproduce the viscoelastic lithosphere dynamics, whereas sand is used to capture the plastic behaviour of slopes and landslides, while climate-driven precipitation is routinely simulated to address slope erosion. All the modelling techniques are well established, minimising the risk of the project. Combining these techniques into a single modelling approach is novel as it reliably captures the feedback between processes acting across vastly different spatial and temporal scales, so far addressed in isolation.
