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.
