Thanks for addressing the comments of the reviewers. As both reviewers suggested minor revisions, I don't think that it's necessary to send the paper back out for review. I have, however, gone through it myself, and identified a number of areas where further clarification would be helpful. My comments are in the attached document. I look forward to seeing a revised version.

Best wishes,
Rebecca

Thanks for your detailed response to the review. I realise that a number of my comments were because of confusion about whether or not you were using grain size data in your calculations, as the data were not previously mentioned. I think that this is an important point to make in the methods, as readers might assume that a remote sensing technique does not require field data. Your explanation about what sets the observed width is an important addition, but which was better described in the response to reviews that in the paper.

I am returning the paper with a very small number of suggestions for very minor revisions, that you should be able to address easily. I'm doing this because I think that the above two points could be more clearly explained, and that making these changes will ensure that readers get the most out of your work. I look forward to receiving a revised version.

Best wishes,
Rebecca

Thanks for responding to those final suggestions. I'm now please to recommend your paper for publication.
Best wishes,
Rebecca

Note: In the previous round, I mistakenly attached the incorrect review file. I am including it here just so that there is a complete record on ESurf.

Dear Kumar Gaurav and colleagues,

Thank you for working with AE Rebecca Hodge and her referees to bring your manuscript into publishable shape. I am happy to follow Rebecca's advice and permit publication of your work in its current form. The paper brings an interesting combination of techniques to bear on a problem of interest not only in the Himalayan foreland, but in fluvial settings elsewhere. I trust that it will receive good attention.

Your manuscript will now be picked up by the Copernicus publishers. Your prompt replies to their queries and requests will help keep the time to print as short as possible. Please note that due to biosafety constraints, Copernicus may need more time than normal to process the manuscript. I iask for your understanding and patience.

Thank you for submitting your work to ESurf.
Best wishes,

Niels Hovius
