Abstract
Aeolian processes involve wind-driven emission, transport, and deposition of sand and dust, with sediment transport serving as a key source of sediment for coastal sand dunes. However, beaches today are increasingly out of equilibrium due to human activities, such as coastal development and climate change, which disrupt natural sediment dynamics and lead to localized erosion and accretion along coasts. This imbalance calls for comprehensive strategies to restore and maintain beach system stability. As predicting sediment transport rates is crucial for determining dune sediment budgets, it is essential to consider wave-driven sediment transport. This paper reviews the impact of wave-driven processes on aeolian sediment transport within beach dune systems. By examining sediment transport dynamics in specific coastal environments, this study aims to shed light on the wave-driven formation of aeolian sediment features. Following the ROSES (RepOrting standards for Systematic Evidence Syntheses) guidelines, this review includes a diverse range of studies sourced from the Scopus, Web of Science, and Dimensions databases. Thematic analysis identified three key areas: aeolian processes, the driving factors impacting aeolian transport, and methods to control wave-induced aeolian transport. The findings of this study advance understanding of the role of waves in shaping aeolian sediment dynamics, offering valuable insights for future research in this field. Highlights Human-induced disturbances disrupt natural sediment dynamics, leading to erosion and accretion along coastlines. The study explores the interplay between wave-driven processes and aeolian sediment transport. It offers a comprehensive approach to understanding the impact of wave dynamics on aeolian sediment. The research provides a detailed review of wave-driven processes influencing sediment transport in beach dune systems. It emphasizes the need for further research to understand the nuanced interplay between wave dynamics and sediment transport mechanisms within coastal environments.
