Abstract
Recently the number of 1D and 2D modelling tools that use the Finite Volume Method with upwind and explicit schemes aiming to solve the SWE together with sediment transport has progressively increased. This work focuses on two issues that arise when extending a numerical code initially designed for water flow to include bedload sediment transport: the upwinding of the sediment fluxes, and how to deal with a non-erodible layer. For both of them simple but effective methods are presented. The Roe ...
