Experimental study on breaching mechanisms of landslide dams composed of different materials under surge waves

After the formation of a landslide barrier lake, additional landslides in the lake area can generate huge waves, which may overtop the landslide dam and eventually lead to breaching failure of the dam. Since landslide dams are natural dams without compaction, the dam materials are heterogeneous, loose and highly erodible, so that the breaching process under wave actions is rather complex. Although a number of model tests have been conducted by...
