Short summary
Short summary
When landslides dam rivers, the impacts can include catastrophic outburst flooding. This work defines a function that combines river valley widths and landslide volumes to find the likelihood that a river will be dammed by a potential landslide or ‘damability’. We apply the method to the Oregon Coast Range and find widespread high damability especially where rivers flow through steep mountains with strong rocks. Our new workflow is flexible and can be applied more broadly to other regions.

Short summary
pyTopoComplexity is an open-source Python tool for multiscale land surface complexity analysis. Applied to a landslide-affected area in Washington, USA, it accurately identified landform features at various scales, enhancing our understanding of landform recovery after disturbances. By integrating with Landlab’s landscape evolution simulations, the software allows researchers to explore how different processes drive the evolution of surface complexity in response to natural forces.
