This dataset contains wind flow and sediment transport outputs derived from Computational Fluid Dynamics (CFD) simulations performed over a natural coastal foredune. The simulations were conducted using a high-resolution three-dimensional topography and calibrated against field measurements collected during the AEOLEX campaign. The dataset includes spatially distributed fields of wind velocity, shear velocity, wind direction, and saturated sediment transport rates (qsat) for three incoming wind speeds: 15 m s⁻¹, 20 m s⁻¹, and 25 m s⁻¹. For each wind speed, simulations were performed over a range of wind directions spanning 180°, allowing for the analysis of wind obliquity effects on airflow and sediment transport. All variables are provided on the computational grid and are referenced to the same coordinate system as the input topography. The dataset enables investigation of the interactions between airflow, sediment transport, and dune morphology, including the effects of slope variability, crest-plateau structure, and three-dimensional topographic complexity. This dataset supports the findings presented in Robin et al., 2026 (Wind obliquity controls airflow and sediment transport over a natural foredune: Insights from 3D CFD simulations, JGR), and is intended for use in studies of aeolian processes, coastal dune dynamics, and model validation or intercomparison.
