Dear authors,

Thanks for submitting detailed online replies to the reviewers comments. I would like to invite you to submit a revised version of the paper addressing the reviewer comments as indicated in your response.

Regarding major point 1 of Reviewer 1 on model robustness, I think you explained the background well in the response and it will certainly be useful to include some of this information into the paper. From my personal experience, I would be very careful to say that late summer low flow augmentation from glacier ice melt (and their changes over time) can be neglected if the fractional area is only 0.5% - in particular in the Mediterranean climate with dry summers it can indeed make a difference. But whether this has implications for the study is possibly another question.

With respect to the comments by Reviewer 2 please remember that you cannot refer to submitted and not yet published papers for essential information. I suggest to use supplementary material for additional figures rather than an Annex, which should be used for method descriptions. With regard to the title, perhaps using the plural “Hierarchies….” may do the trick?

Regards
Kerstin

Dear authors,

as you can see from the reports, the reviewers are generally satisfied with the revisions. They only raised a few pending issues of editorial/technical nature that I suggest you look at and improve before uploading the final files.

Thanks and best wishes
