I have now received reports from two referees and thank the authors for their detailed responses to the referees’ comments (a third referee did not provide their report on time). Based on these two reviews and my own reading of the manuscript, I find that the paper fits the aims and scope of HESS, but that the manuscript requires some improvements.
Improvements can be made specifically by: providing further methodological details (on the model setup; the rainfall temporal patterns); providing discussion of the methodological choices (including rationale for choosing the RCP8.5 scenario; discussion of chosen scaling methods); and improving the figures (including font size of legends where reasonable, incl. the revised Figure 1). Additionally, I find that (1) the title should reflect the fact that the study is based on one watershed; (2) the abstract and introduction could be streamlined for greater clarity (e.g. in the abstract, it might be clearer to describe the research gap before introducing the research questions; in the introduction, some of the sentences feel a little disconnected, e.g. adaptation is not defined); (3) sections 4.2-5 are mostly descriptive, and could provide more insight on the implications of the work and how these findings relate to the previous literature.
Both referees have requested to review the paper again after corrections have been made, and I consider that to be a fair request. I would therefore like to invite the authors to upload a revised manuscript for further review by the referees, incorporating the proposed changes and additions, and making any other modifications where they see fit.
I look forward to receiving the revised manuscript.
With best regards,
Louise Slater

Dear authors,

Thank you for your detailed and thorough revisions to the manuscript, which has now been re-reviewed by the two referees. They have both made some minor suggestions for improvements/clarification, which seem reasonable and should be straightforward to address. I would therefore like to invite you to submit a revised final version, taking these suggestions into account.

With best wishes,
Louise Slater

Dear Authors,

Thank you for uploading the final revised manuscript. I look forward to seeing it in print!

Sincerely,
Louise Slater
