Suggestions for revision or reasons for rejection

Some minor comments to the revised manuscript.

[1] Title: the title is still a bit confusing (and long). Here you have some issues which are missused in the title that need revisions. Also, check their use throughout the text (e.g. abstract, introduction, discussion, conclusions).

[1.1] "Flanking" is a term that it is usually, if not always, employed when describing the excess of erosion downdrift seawalls and revetments. Its use in the context of the paper will be confusing for most of readers. It will be much simpler to use something like "downdrift erosion" or similar.

[1.2] I think that authors missuse the term "Analytical approach". I assume that they are referring to the use of an analytical model to simulate shoreline erosion. However, this is not "analytical approach".

[1.3]Is the model only applicable to "natural groins"? I presume that not.

[1.4] A possible option could be something like "An analytical model for shoreline development downdrift of groins". You do not need to use this, but please select a more appropriate text than the current one.

[2] Section 3: change the name to simply "Wave and shoreline data"

[3] Section 4: change the name to just "Results"
[3.1] I suggest to remove the subheadings 4.1 and 4.2 to present the results. Include a first sentence where you describe what results you are going to present in the chapter. State that, first, you are going to compare the performance of the analytical model with respect to the numerical model and, then the model results are compared with shoreline data.
[3.2] Avoid to introduce new formulas or methods here. (e.g. eq 20 and 21). They should have been introduced in section 2.

[4] Section 5: change the name to "Discussion"

[5] Section 6: change the name to "Conclusions"

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).
