The hazard chain of landslide-river blockage-outburst flood is the most common hazard chain caused by landslides. A database based on existing landslide cases was established in this paper to investigate the assessment formulas of river blocking risk, dam stability, and peak flood discharge after the dam break. A risk assessment model of the landslide-river blocking-breaching hazard chain was established with the vulnerability downstream. The case of the Baige landslide verifies the applicability of the model. This model can be used in a landslide-prone area to predict whether it will form a relatively massive river blockage after the landslide occurs, whether the landslide dam formed by river blockage will breach in a short time, as well as the impact of the outburst flood on the downstream area.
