Dear authors,

Thank you for your open and informative responses to the referee comments and to my own. I believe that the paper will be a valuable contribution to the scientific literature, once the changes you suggested have been implemented.

I do not believe that additional analysis is necessary to make the main points of your study, i.e. that increasing resolution of a GHM does not necessarily improve hydrological prediction. The referees' critique that the chosen GHM may not adequately represent hydrological processes at the chosen catchments would likely apply to most other GHMs as well, while tests of adequate representation of processes are not easily performed. Your case study may not be able to answer the general question if increased GHM resolution has the potential to improve predictions, but it does contribute some evidence for the contrary conclusion. This rises the question whether we should not invest in improving process represenation instead of increasing spatial resolution. The points raised by the referees and your replies are valuable pieces of this discourse and I look forward seeing them reflected in your revised paper.

Could you also provide a script or instructions on how to reproduce the results using the data mentioned in "Code and data availability"? I looked at the link but got the impression that it may not be straightforward to reproduce your results with the information given.

Dear Authors,
Thank you for addressing the various comments and concerns raised by the referees. I think that due to the different perspectives added by the referees and your open discussion of these perspectives in the manuscript, the paper will be a very interesting and valuable addition to the scientific literature. I have not found an acknowledgement section. Given all the helpful and constructive comments submitted by the referees, I think it would be fair to acknowledge their input. You might also like to acknowledge your funding sources, so I am marking this as "accept subject to technical corrections" in order to give you the opporunity to do so.

Best regards,
Stan
