Abstract
The paper presented a 3D numerical model for calculation of flow and sediment transport in channels. The flow is calculated by solving the Reynolds equation with hydrostatic assumption. Suspended-load is simulated by transport equation while bed-load is calculated using empirical formula. Bed transformation is obtained by solving an overall mass-balance equation. All equations are solved using finite volume method. The model is applied for study of bed deformation of VamNao river in the Mekong delta.
