Dear authors,
your paper has been revised by two reviewers, in addition to a short comment from a third external reviewer. One reviewer suggested technical changes (however indicating some useful points for the improvement); the second reviewer raised major issues with some constructive indications to improve the work; the third external reviewer, who provided a short comment, indicate a lack of mention of recent relevant studies that have applied mathematical modeling and optimization strategies.
I also read your paper and the public responses; I'm satisfied with your replies and the work indeed is interesting; I think you should have a chance to propose a revised version of the work. Therefore I decide to reconsider thig paper after major revisions.
Just an editorial note from my side, since all the three reviewers involved in the public discussion mentioned some references or suggested to insert few missing references in the manuscript: an author is not obliged to cite the references suggested by the reviewers.
In submitting your revised version, please provide a detailed list of the changes made to the text and a detailed list of your responses to the reviewers’ comments. Please deserve particular attention to the English language, and also provide a legend of color in figure 6.
Please note that this editorial decision does not guarantee that your paper will be accepted for final publication in NHESS. A decision will be made when the revised version will be available and evaluated.
Best regards
Paolo Tarolli

Dear Authors,
your article has been further revised by one reviewer and by myself. At this stage, only a few technical issues remain to be fixed. Please follow the reviewer's #1 indications.
From my side, I would suggest, if it is possible to improve the clarity of figure 3, 4 and 6; the "black lines" or roads are too black and too highlighted; I printed these, they look not optimal, maybe making the roads in grey, could better emphasize the other colours. Also, the figure 1 could be improved according to such a suggestion.
Thank you for submitting your work to NHESS.
Best regards
Paolo Tarolli
