Short summary
Short summary
Most of the tools available to model sediment transport do not account for complex physical mechanisms such as surface-wave-driven processes. In this study, a new model, sedInterFoam, allows us to reproduce numerically complex configurations in order to investigate coastal sediment transport applications dominated by surface waves and to gain insight into the complex physical processes associated with breaking waves and morphodynamics.

Short summary
Sediment transport refers to the displacement of granular materials, such as sand and gravel, under the combined action of gravity and fluid flow. This study presents an open-source numerical model developed to investigate this process, with particular emphasis on the migration of an isolated dune. Beyond this specific application, the model has broad potential, including the analysis of erosion around engineered structures, ripple formation, and the morphological evolution of river systems.
