Short summary

Damming of rivers is an important secondary effect of landslides due to upstream flooding and possible outburst floods in case of dam failure. For preliminary regional hazard and risk assessment of dams formed by rock slope failures in Norway, we developed semi-empirical relationships to assess the height and stability of dams based on an inventory of 69 dams formed by rock slope failures in southwestern Norway and published landslide dam inventories from other parts of the world.
