Dear Dr. Martín-Vide and coauthors
Thank you for the submission of your very interesting manuscript “What controls the coarse sediment yield to a Mediterranean delta. The case of the Llobregat river (NE Iberian Peninsula)”. As you know the process of peer review and publication in Natural Hazards and Earth System Sciences (NHESS) is a two-stage process involving the scientific discussion forum Natural Hazards and Earth System Sciences Discussions (NHESSD). The first stage, corresponding to the open discussion has ended. From now on begins the second stage that follows the usual and non-public peer-reviewed process. I would like to remind you that the pass to the second stage is no guarantee whatsoever that the paper will be accepted for publication in NHESS. This will depend on the comments of the referees, and your ability to respond properly to the comments received.
As you know, two reviewers have now provided detailed reviews, which you have replied in thoughtful detail to. One review recommended major revision and the other one recommended minor revisions (although I have a feeling some of the revisions suggested by this last one are not so minor--they may take a bit of time!), and therefore I would like to invite you to submit a revised version of your manuscript.
Would you please also provide an ‘author’s reply’ to the reviewers (feel free to use the same words that you used in what you have already uploaded). Please can you also include a track changes document between the old manuscript and the new one (you can include this as part of your ‘author’s reply’).
Since the comments of the reviewers are a bit dense, and in order to make the document with the answers easier to read, I ask you for a format change. For example, in the response document they may use different font color or italics to distinguish the reviewer's comments from their own responses, and to distinguish what is a reproduction of some new text fragment in the revised version.
I look forward to seeing the next version of your manuscript which I will then send out for further review to either the previous reviewers (if they agree) or new reviewers.

Dear Dr. Martín-Vide and coauthors
The first revised version of your manuscript NHESS-2020-72 entitled " What controls the coarse sediment yield to a Mediterranean delta. The case of the Llobregat river (NE Iberian Peninsula)" which you submitted to NHESS, has been reviewed.
I am very happy to grant conditional acceptance of the paper, subject to you making satisfactory revisions as the referee proposes. These revisions are minor, in the sense that there are no major recalculations or major analyses required, but there may be less-major analyses needed and there are several important revisions to the text that are necessary.
In your revisions, please address all the points made by this reviewer, make suitable edits to the manuscript, and include a point-by-point response to each reviewer comment with your response.
I will study your responses and determine if the edits were handled satisfactorily. I would like to receive the revised manuscript as soon as is convenient. I feel confident that, pending careful revisions as outlined above, I will be able to publish your paper in Natural Hazards and Earth System Science.
Once again, thank you for submitting your manuscript to NHESS journal. I look forward to receiving your revision.
Regards

Dear Dr. Martín-Vide and coauthors
Thank you very much for the revised version of your paper. Although we have asked only for minor revisions in the sense that there are no major recalculations or major analyses required, following the editorial rules we have told you “ In your revisions, please address all the points made by this reviewer, make suitable edits to the manuscript, and include a point-by-point response to each reviewer comment with your response. I will study your responses and determine if the edits were handled satisfactorily. “
However, you have sent us exclusively the paper with track changes but not a letter answering the questions proposed by the review that he has included in your manuscript and he has also sent you directly by email. In the same way the review asked for “changing the structure to a more classical one instead of so many sections with a mix of methods, results and discussion. As it is now is difficult to follow by the reader.” But as far I have seen the structure has not been modified.
Consequently, I kindly ask you to send the new version of the article accompanied by the letter with the reviewer's comments and your response to each comment, as well as the document with track-changes. In the new version, I ask you to modify the structure of the article as requested by the reviewer (for instance, paragraphs 4 and 5 of the Introduction should be moved to another section where you explain the Area of study that could be integrated with part of section 2 and other sections)
At the last meeting of the NHESS editorial committee it was insisted that only those papers related to Natural Hazards will be published. So, I ask you to include a paragraph (for example in the Introduction) or a section on how sediments affect flooding in the Llobregat, or vice versa. Besides this, please, clarify in the Introduction and abstract which is the main objective of this paper and the argument that you will follow along it. Finally, I would suggest you review the English language (for instance, it is not “in the XX century”, it is “in the 20 century”).
I hope to receive in a near time your paper with all the proposed modifications as well as the answer letter accompanied by the article with track-changes.
Best Regards

Dear Dr. Martín-Vide and coauthors,
Thank you very much for the new version of your paper “What controls the coarse sediment yield to a Mediterranean delta. The case of the Llobregat river (NE Iberian Peninsula)”. I consider that you have answered properly all the questions that the referees and myself have made you and that the new changes introduced in the paper have improved it considerably. Consequently, it is a pleasure for me telling you that your paper has been accepted to be published as it is.

Hoping to receive more contributions from you in the future, to be published in NHESS,

Kind regards
