I am very much looking forward to seeing the revised manuscript. The authors have done a good job of replying the the reviewer comments in a detailed and conscientious manner. Most responses are very specific and clear exactly what will be changed, others promise revisions which are not yet specified (i.e. an improvement to the discussion section). Both the reviewers have positively requested to further review the revised manuscript. Therefore I suggest the authors complete their manuscript revisions and I will send this back to the 2 reviewers for final comments. I appreciate the diligence of the whole process so far, best wishes, Jim

Dear Authors,

You have done an excellent job in the revised submission of your paper, many thanks for your diligence. I am now sending this back to the reviewers as they both requested and I believe you have provided them with plenty of information to make a clear decision on the manuscript. Thank you very much for your time, Jim

Dear Authors, please note some comments made for text improvement changes by reviewer #1 and some small clarifications. Both reviewers (who reviewed your initial submission) now have no problem with the technical content of the paper and are happy for this to proceed to publication in HESS. Thank you for your time in modifying the paper, best wishes, Jim

Dear Authors,

I am now very happy with the paper and the improvements to it's readability. So we shall move to final publication, best wishes, Jim
