Investigating the failure mechanisms of cascade landslide dams under overtopping conditions: an experimental approach.

ABSTRACT: Under strong earthquakes and extreme rainfall conditions, landslide clusters near rivers may block incoming water flows, forming cascade landslide dams. When subjected to extreme hydrological conditions, these cascade landslide dams can experience overtopping, which erodes and entrains material from the dam surface, compromising dam stability, which can potentially lead to outburst flooding. Although existing research provides valuable insights into landslide dam failures, it falls short in addressing the complexities of cascading failures in dam groups. The influence of various factors on this intricate process is still only partially understood, highlighting the need for a comprehensive understanding of dam surface evolution and flood flow dynamics specifically within the context of casc
