DOI: 10.1007/s10064-018-1255-0
Abstract: The deposition morphology of a landslide dam determines the position of initial breach and sequentially affects the direction of lateral erosion. Twenty-seven discrete element numerical simulations were carried out to investigate the deposition morphology of… read more here.

DOI: 10.1016/j.sandf.2018.05.012
Abstract: Abstract Due to the rapid cracking, sliding and packing of its geomaterials, a landslide dam (LD) is usually weaker in structure than the undisturbed ground and is more vulnerable to seepage loading. In addition, since… read more here.
