Numerical data for "Barchan dune responses to a pair of obstacles"

This simulation models the formation and evolution of a barchan dune under turbulent flow conditions, as it interacts with obstacles placed within the domain. It captures the coupled dynamics between the fluid phase and the granular bed, allowing for the analysis of sediment transport, dune migration, and morphological changes. In particular, the presence of obstacles modifies the local flow field and sediment flux, influencing dune shape, displacement, and stability over time.
