Abstract

BED-LOAD TRANSPORT is effective on river bed stability and Morphology. Therefore, modeling this phenomenon is very important in the field of hydraulics engineering. BED-LOAD TRANSPORT occurs by SALTATION at low to medium shear stress and by sheet-flow at high shear stress. In the present paper, the hydrodynamics of transport in thesaltationand sheet-flow regimes under unidirectional flow is studied using a Lagrangian model based on I-SPH method. The fluid and sediment phases are modeled separately as Newtonian and non-Newtonian fluids respectively.Fluid-sediment interaction is modeled using drag force to define interaction mechanism. To calibrate and validate the numerical model, the result is compared with experiments. There is a good agreement between them that illustrates the applicability of the present model in the simulation of both SALTATION and sheet-flow regimes hydrodynamics.
