Enhancing an Analysis Method of Compound Flooding in Coastal Areas by Linking Flow Simulation Models of Coasts and Watershed
Round 1
Reviewer 1 Report
The reviewed paper concerns the numerical analysis of flooding in the coastal area of Marine City, Korea. The authors combined different codes to achieve reliable results taking into account wave, tide and storm surge. The obtained results were verified against the data recorded during Typhoon Chaba (2016). The carried out research is interesting although the authors failed to point out the key novelty of their research. The title is self-descriptive and represents the content of the manuscript. The abstract provides a clear view of the content of the paper. The introduction section should better describe the mathematical aspect of the discussed models and emphasize the novelty of the presented research on the background of contemporary science. The research object is properly described with the satisfactory level of details but the applied models and their settings are not well discussed. For example, the authors simply list out the available turbulence models of the FLOW-3D (lines 133-134) but they do not indicate which of them was selected. The meshing is not discussed at all – the numerical mesh is simply depicted in fig. 5 and 7 but the authors did not provide any information concerning the mesh quality, or even number of cells. The boundary conditions should also be better discussed: why is the symmetry applied; why the output boundary is limited only to the investigated area. The authors tried to verify the obtained results against the data recorded during Typhoon Chaba but the verification is not quantitative. The conclusions are supported by the obtained results but they are very general.

The introduction section should better describe the mathematical aspect of the discussed models and emphasize the novelty of the presented research on the background of contemporary science.
-> I modified the introduction to emphasize the novelty of this research by presenting methodologies (model and analysis range etc.) and limitations on previous studies.
(Line 49-89)
The research object is properly described with the satisfactory level of details but the applied models and their settings are not well discussed. For example, the authors simply list out the available turbulence models of the FLOW-3D (lines 133-134) but they do not indicate which of them was selected.
-> I totally modified the manuscript and added the contents as your request.

The meshing is not discussed at all – the numerical mesh is simply depicted in fig. 5 and 7 but the authors did not provide any information concerning the mesh quality, or even number of cells.
-> I totally modified the manuscript and added the contents as your request.
(Line 226-237, Figure 5 and Table 1)
The boundary conditions should also be better discussed: why is the symmetry applied; why the output boundary is limited only to the investigated area.
-> I totally modified the manuscript and added the contents as your request.
(Line 247-257 and Figure 8)
The authors tried to verify the obtained results against the data recorded during Typhoon Chaba but the verification is not quantitative. The conclusions are supported by the obtained results but they are very general.
-> I added the quantitative validation results to section 3.3 and described the conclusions in more detail with the results.
(Line 310-321)
Thank you.
Reviewer 2 Report
In the present paper the authors have improved an analysis method about the flooding in coastal areas such as in Korea.
By combining different natural phenomenon, such as: Tide and storm surge or water level, the authors are able to predict the same results, for the inundation area and its depth, as the Typhoon Chaba.
Line 127, describe more the N-S equations: assumptions, interesting elements of it, solvers selected, etc.
Line 127: describe more the grid: which kind of, number of cells, etc.
Line 127: add a grid convergence study.
Line 115 in Figure 3: add a legend of the schematic.
Line 175 in Figure 5: add a legend of the meaning of the colors.
Line 211 in Figure 10: remove the window frame and only show the picture.
And in general, please make sure that, in every picture shown, every text or number is possible to see (or size text or with better picture's quality)
Make sure that the units are shown correctly, for instance: Line 107, 231, etc.
Perhaps the authors could cite this paper (10.1061/(ASCE)WR.1943-5452.0000497) and take a look of how they performed the coastal flood risk simulation.

-> I quoted the article in the Introduction as a literature review (11th reference).
Thank you.
Reviewer 3 Report
The authors used several well known software to set up a very impressive framework for inundation analysis considering compound flooding. I read the paper with great interest and pleasure. Overall, the paper is well written and the technical details are given with good clarity. I believe the paper will draw a lot of attention from the field. Therefore I suggest the paper to be accepted for publication. I only have some minor comments for the authors:
- Line 57, "[12] proposed..." is not a very conventional way to place reference in the beginning of a sentence. The authors can do "Ref. [12] proposed..." or "Author et al. [12] proposed..."
- Please make the photo sources information in Fig 2 a foot note.
- In line 169-170, please provide a reference to Korea Hydrographic and Oceanographic Agency, preferably with a url.

Round 2
Reviewer 1 Report
The paper has been thoroughly rebuilt since my previous review. All my previous doubts/questions have been adequately addressed by the authors. Moreover, the new content has significantly improved the scientific quality of the manuscript and it can attract more attention from the readers. Therefore I recommend to accept it in the previous form.
