Transitory distribution of the suspended sediment in a unidirectional non-uniform flow

A 1DH modeling is implemented to study a particular case of transport in suspension along a channel corresponding to a 2DV problem. In order to include the vertical dimension, a model named α-β is used. This latter was developed to describe the vertical distribution of suspended sediment in a flow corresponding to an unsteady and/or non-uniform state, and including deposition and resuspension phenomena (SANCHEZ, 2013). Results show that in some regions of the studied domain, the α-β model describing the vertical distribution of suspended sediment, can be simplified because its two parameters (α and β) remain constant.
