Conventional numerical methods for the simulation of sediment transport solve single-phase hydrodynamics and advection-diffusion equations in combination with the empirical relations. These simplified methods are not capable of dealing with the highly-dynamic sediment movements which often induced by highly-erosive flows (e.g., floods) or powerful outer forces (e.g., landslides). Two-phase methods have recently proven their potential for such sediment flow problems. Among them the multiphase mesh-free particle methods provide a unique opportunity for the simulation of large interfacial deformations and fragmentations involved in two-phase sediment-water system. This article briefly overviews example applications of a multiphase mesh-free particle model for two-phase flow of water and sediments in different configurations. The model treats the sediment material as a continuum (a visco-plastic fluid) whose behaviour is predicted using a stress-dependent Theological model. The model is validated and applied for highly-dynamic movement of sediments in cases such as submarine landslide and sediment erosion. The results of this study, evaluate the capabilities of mesh-free particle methods for complex sediment transport problems and provide a more thorough understanding of their complex mechanism and processes.
