Executive editor
I support the proposal of the handling editor to make it a highlight paper. Using a shoreline change model, the paper analyses the erosion of sand in Wolcheon Beach, South Korea, due to longshore sediment transport (LST) before conducting large-scale coastal construction projects. The results, which provide insights into methods that minimise potential coastal damage, can be of interest to the readers.
Short summary
This paper emphasizes the significance of evaluating changes in nearby shorelines prior to undertaking large-scale coastal construction projects, thereby offering insights into strategies that can minimize potential damage. As a result, the study provides an opportunity to explore the consequences of harbor and fishing port development, as well as large-scale reclamation, which can deform wave fields in coastal areas and intensify coastal erosion.
