Dear authors,

The two reviewers find the manuscript suitable in general, but ask for considerable clarification and revision before being able to make a decision on acceptance.
They both question the originality and novelty, so besides the many requested clarifications, please carefully work out the specific niche and new contribution this study makes to science, also by better placing and comparing it within the field of literature.
Also, please address carefully some of the requests for more in-depth insights well beyond the rather superficial online-replies made to the reviewers so far! After that, the reviewers and I will carefully reconsider whether the manuscript can be accepted for HESS.

Regards
Kerstin Stahl

Dear authors,

thanks for addressing the reviewer comments, which have been found satisfactory by one reviewer and myself. The clarifications will help the readers and the additional information will help put the results in perspective.

I am still not enthusiastic about the mixed results and discussion section, which is now also very long. However, since the reviewers did not comment on this, I am happy to accept the manuscript as it is now.

I have two editorial suggestions though for the final manuscript upload: please give it a thought to make two or three subheadings in the now rather long results and discussion section to allow an easier navigation for those readers first scanning the paper. In the text, the use of articles and prepositions could still be improved.

Thanks for this interesting contribution and best regards.
Kerstin Stahl
