Abstract: The numerical models for computing simultaneously the liquid flow and the bed loads in natural channels exist recently. Actually, they have reached such a level of development that they can be used in engineering. These models can simultaneously solve the equations related to the liquid flow, solid transport and the deformation of the bed. We will present in this study approximate solutions using the equations of St-Venant related to the non stationary flows in natural channels with removable bottoms.
