Abstract A complex interface exists between water flow and solid particles during hydraulic soil erosion. In this study, the
particle discrete element method (DEM) has been used to simulate the hydraulic erosion of a granular soil under
moving bed conditions and surrounding terrain changes. Moreover, the weakly compressible smoothed particle
hydrodynamics (WCSPH) approach has been exploited to simulate the instability process of the free surface fluid
and its propagation characteristics at the solid–liquid interface. The influence of a suspended medium on the
water flow dynamics has been characterized using the mixed viscosity concept accounting for the solid–liquid
mixed particle volume ratio.… More >
