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

Mechanisms of the Non‐Uniform Breach Morphology Evolution of Landslide Dams Composed of Unconsolidated Sediments During Overtopping Failure

“…In the literature, these stages are also referred to as the headward, accelerated, and attenuated erosion stages (G. G. D. Zhou et al., 2019). Note that other works have also designated the dam breach hydrograph into stages using different criteria (i.e., outburst discharge or erosion morphology) other than the breach discharge and stream power (Peng et al., 2021; Ruan et al., 2021). Movies showing the erosion process are provided in References in Supporting Information S1.…”

Experimental Investigation on the Breaching Process of Landslide Dams with Differing Materials under Different Inflow Conditions

“…A rigid riverbed was used in the downstream area of the flume. The rigid riverbed had no sediment to simulate a rock riverbed [ 37 , 47 ].…”

“…The Xiaogangjian landslide dam was caused by a shattering-sliding type of landslide consisting of dolomite interbedded with dolomitic limestone [ 33 ], which contained much more coarse grains than the above two landslide dams. In this study, the grading curve that represented the average level was selected from the sieving test results to prepare the model dam [ 47 ], making the experimental grading similar to that of natural landslide dam [ 55 ]. A similar method has been adopted by numerous researchers [ 14 , 56 , 57 ].…”

Deposition characteristics of debris flows in a lateral flume considering upstream entrainment

“…Debris flow injections from gullies into a river generate sediment deposits which can create a significant degree of obstruction of the river section or even a debris dam (Dong et al, 2011;Tang et al, 2011a;Ni et al, 2014;Liu et al, 2014;Shi et al, 2018;Peng et al, 2021;Zheng et al, 2021). The morphology and hydraulic regime of a river are disrupted during the deposition process and a specific type of disruption is the formation of a deposit lobe (Peng and Zhang, 2013;Chen et al, 2019).…”
