Interactions between the uprush and backwash waves around a swash zone cause a complex water surface with wave breaking. Infiltration and exfiltration on a permeable beach face produce significant effects on the bottom shear stress. Abrupt changes of

The mechanism of a ripple formation process under swash zone, which is shallower than surf zone, has not yet been fully investigated due to the difficulty of a precise measurement or of an implemen...

This paper presents a numerical model to simulate density currents using an Incompressible Smoothed Particle Hydrodynamics method with accurate schemes associated with the pressure calculation. The suspended sediment is treated as a concentration def

Numerical simulations were performed for morphodynamics with free water surface fluctuation using the DEM-MPS method, which employs the discrete element method (DEM) and the enhanced moving particle semi-implicit (MPS) method for the solid and liquid

A regime of highly concentrated sediment transport, or sheetflow, which is observed around coastal surf-zone, has significant impact on a coastal process. However, it is difficult to directly measure an inner-structure of the sheetflow from experimen

The paper presents a numerical model for simulating a granular flow and its deposition on an inclined bed. A granular material is described as an elastic–plastic continuum and its constitutive law, namely Hooke's law, is discretized on the basis of

It is necessary to accurately predict the diffusion and deposition range of a large amount of sand dumped from a hopper barge for efficient reclamation in a coastal area. Many previous studies have proposed useful models to simulate the diffusion beh
