dc.description.abstract | In this work efficient semi-implicit methods for sediment bedload transport models with
gravitational effects under subcritical regimes is proposed. Several families of models with
gravitational effects are presented and rewritten under a general formulation that allows
us to apply the semi-implicit method. In the numerical tests we focus on the application
of a generalization of the Ashida-Michiue model, which includes the gradient of both the
bedload and the fluid surface. Analytical steady states solutions (both lake at rest and non
vanishing velocity) are deduced an approximated with the proposed scheme. In all the pre sented tests, the computational efforts are notably reduced thanks to the proposed method
without losing the accuracy in the results | es |
