runoutSIM - An R package for regionally simulating landslide runout and connectivity using random walks

runoutSIM is a free, open-source R package for simulating the potential paths and impacts of landslides like debris flows. It models, at regional scales, how far and how fast material may travel and whether it could reach roads, rivers, or other downslope features. The package also estimates the likelihood of connectivity between source and impact areas, supporting hazard assessment and advancing process-based modelling approaches.
