Open source model demonstrates sediment transport and morphodynamics in a dynamic setting, indicating its practical applications in environmental studies.
The development of an open source numerical model for sediment transport and morphological evolution is presented. It relies on the Arbitrary Lagrangian Eulerian (ALE) method to track the bed interface position over time. The sediment bed acts as a moving boundary whose motion depends on sediment fluxes and a dynamic mesh is employed to adapt the computational domain to the dynamic boundary. The implementation of the different components of the model (bedload, suspended transport, avalanche, etc.) is validated using a series of academic benchmarks. Finally, in order to highlight the model capability, an application to the study of a lone dune migrating under the influence of a steady flow is presented.
