Sheetflow is the key to predict a beach deformation because massive sediment is transported by a high shear stress. To understand the mechanism of sheetflow dynamics, numerical simulations and experiments have been performed, however, sheetflow is a highly-concentrated particulate flow internal structure of which, so it is difficult to be investigated experimentally. In the present study, numerical simulation of a sheetflow by using of high resolition model the solid-liquid two-phase turbulence flow is performed, and the internal structure of sheetflow layer has been investigated in detail by a high-resolution solution in 1/10 times of particle diameter.
