Dear authors
you received tow detailed and constructive reviews and I really liked your reply to them. Your work fits in HESS and has some innovative aspects, mainly related to the energy dissipation and soil loss in headcuts. Also the agreed deepening of the discussion of implication of your findings are welcomed and will improve the impact of your work. I was pleased to read you will make all data of your interesting experiments available. This can be done attached to the paper
I look forward to the revised version which will go for final review by one reviewer and myself

Dear authors,

I happy to inform you I have accepted your manuscript with minor revisions for publication in Hess. I think the revised version is well improved. I have a few technical remarks that I would like you to incorporate when submitting the final version which relate to summary / conclusion section and the figures

Can you rephrase the summary in terms of conclusions. It is not so useful to repeat the percentages. Please write the last section in terms of scientific conclusions (answering your research objectives.

Second, please check English in part Data Availibility. I would like to urge you to make the data available as much as possible.

Third: Figures.

Fig 2: photo panel description should be in figure caption (Figue 3. Panel a) ..., b) ... etc.
It is OK to indicate things in the photo but the figure description should be below. Please only use black and white for letters, lines and symbols as 'colors and especially red is not visible to everybody. Also try to align the text. Use black or white also for panel indication without grey background

Fig 3: same

Fig 4: in panel b-d-f, please align formula info (put all three in same location in their panel)

Table 1: please add some space between constants and symbols to improve readibility. All formulas are at 0.01 significant so it seems to me the double asterix can go out

Table 2: the same, maybe indicate which expression have not 0.01 significance level

Fig 5: please do not use red text in figure. Try to place legend outside the box (fitting formula is OK, but legend and extra text (like you do in fig 8)

Fig. 7: same as fig 5

Fig 9: use black for panel indication. Describe panel in figure caption

Fig 10: use black for panel indication and text in figure

Fig 12: try to align formula text in panels to be at same height and distance from side

Fig 13: use two grades of grey to indicate parts, use black panel indications

Fig 14: black text. Formula does not need bold letter font


I look forward receiving the final version,
best Thom Bogaard

Dear authors
I thanks you for the improved figures and conclusions section. The paper is ready to be published. A few small notes to improve when uploading final version
Section 5: please use heading conclusion (not summary)
L729 (track-changes version). weakened -> replace with 'decreased'
L730: lightly -> replace with 'slightly'
Fig 3: please use white text in panel (b)

Congratulations and thanks for publishing your work in Hess
