The paper is to examine how much wave energy reduction is provided by the transmission rate of a submerged breakwater and what impact the diffraction process on the shoreline behind the structure and the longshore sediment transport.

Short summary
Recently, along the east coast of South Korea, seasonal beach erosion has been induced by structures which severely block the supply of sand from the upstream side. This study proposes a coastal solution that can predict the maximum indentation point in downdrift erosion formed downstream of groins by applying a parabolic bay shape equation (PBSE).

Short summary
This study aimed to quantitatively assess erosion risk. Methods for assessing each potential were proposed, and the corresponding erosion risk was calculated by introducing a combined potential erosion risk curve presenting the erosion consequence. In addition the method for verifying the risk was examined for the east coast of South Korea. We believe that our study makes a significant contribution to the literature and plays a key role in identifying methods that prevent erosion.

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.
