Abstract
Landslide dams are caused by large-scale slope collapse. Predicting their failure is important because hazardous flooding may result downstream when landslide dams burst. Accurate prediction of a landslide-dam formation which means height and length via landslide maps that show two-dimensional figure but does not consider landslide depth is needed for a countermeasure against the sediment disaster caused by landslide dam. In this study, past landslide dam failures were investigated. Relationships between landslide dam formation and the topographical and geological characteristics of the region were established to improve landslide dam analysis for more accurate prediction of dams’ structural integrity.
