Abstract. Knowledge of how debris flows result in the fan-shaped morphology around a channel outlet is crucial for mitigation debris-flow-related disasters and investigation previous sediment transport from upper channel. Therefore, using flume connected to deposition area (inundation plane), this study conducted fan-morphology experiments assess effects differences grain-size distribution with...

The driving force for coarsening is provided by the excess interfacial free energy. In a system with isotropic interface energies, classical coarsening theories can predict the evolution of the sizes of spherical crystals. However, if the interfaces are anisotropic, crystal growth and shrinkage may be limited by the surface attachment/detachment rate, the motion of ledges, or the nucleation of ...
