Wave-driven process influencing aeolian sediment transport in beach dune systems: A review

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.
