Phenomenon of sediment transport in a limited depth of water are considered
in the present work through the use of a numerical approach.
The physical problem is modeled through the Shallow-Water equation
coupled with the Exner one to describe the time evolution of bed and coastal
prole. The spatial discretization of the governing equations is carried out
by a nite-volume method and a modied Roe scheme designed for nonconservative
systems.
The principal contribution of this work concerns sediment transport modelling
with an analysis and comparison of dierent models. In particular four
models of solid transport discharge are considered.
Other modelling improvement implemented in the 1D numerical code are
also analyzed and treated. It includes the introduction of bed friction term
in the Shallow Water equations as well as the treatment of wetting-drying
interface modeled, in particular, for coastline evolution analysis.
