Dear Fritz and Philippos,
Thank you for working with AE Sebastien Castelltort and his referees to improve the robustness and clarity of your manuscript. I am happy to follow his advice and to approve publication of the manuscript. However, I ask that you invest a bit of time in tightening up the text. As an example, I have edited the abstract.
I also suggest that you change the title of the paper as per the abstract document. I understand that you want to avoid suggesting certainty of flow regime assignment, but prevarication in the title is not helpful. my alternative does not imply a 100% link between imbrication an flow regime.
Finally, I would like to ask you to adjust the use of the word imbrications throughout the manuscript. If you describe the general phenomenon of imbrication, then the singular is appropriate.
Thank you for submitting your work to ESurf!
Best wishes,
Niels Hovius
