“…Conversely, larger gaps render buildings virtually independent, reducing the funneling effect and less significantly altering streamwise velocity. The same model was used to study the influence of a row of ten beach buildings constructed on poles, focusing on understanding airflow, wind-induced erosion, and deposition patterns around the buildings [50]. The main finding is that by elevating buildings on poles, bed shear stress underneath and between them increases due to airflow compression and acceleration, which extends downstream farther than for buildings directly on the surface, potentially enhancing sediment transport towards the dune foot.…”

Coastal dunes, formed and shaped by aeolian sediment transport, play a crucial role in ecosystem services and act as natural flood and coastal erosion defenses. This paper delves into theoretical equations and numerical models predicting sediment transport. Numerical models like cellular automata, XBeach-DUNA, the coastal dune model, and others are analyzed for their ability to simulate dune morphology, erosion processes, and vegetation impacts accurately. Evaluated are field observation and measurement techniques, such as sand traps, impact sensors, and optical sensors, for their precision in quantifying aeolian dynamics. Further examined is the effectiveness of vegetation and fencing in dune stabilization, noting species-specific responses and the influence of fence design on sediment accumulation. These tools offer insights into optimizing aeolian sediment management for coastal protection. By conducting a systematic review and connecting theoretical, empirical, and modeling findings, this study highlights the complex challenge of measuring and managing aeolian sediment transport and proposes integrated strategies for enhancing coastal dune resilience against the backdrop of climate change and erosion. This study’s objectives to bridge gaps in current understanding are met, highlighting the need for a multidisciplinary approach to coastal dune management and conservation, especially combining wind- and wave-driven processes.
