Reviewer 1 Report
Reviewer compliments authors on their thorough investigation as the analysis of highly aerated flow on a stepped chute is of great importance for hydraulic engineering. However, the authors should consider the following remarks in their next revision:
1. English should be improved and authors should use appropriate technical terms (e.g. in lines 121-122 authors state: "...storing each pixel as 8 zeros and ones... which should be stated "storing each pixel in 8 bits").
2. Authors should clearly state that their method (in contrast to PIV) doesn't discern the velocity plane. E.g. side view velocities can belong to different longitudinal sections.

Reviewer compliments authors on their thorough investigation as the analysis of highly aerated flow on a stepped chute is of great importance for hydraulic engineering. However, the authors should consider the following remarks in their next revision:
The authors want to thank Reviewer #1 for his kind compliment.
- English should be improved and authors should use appropriate technical terms (e.g. in lines 121-122 authors state: "...storing each pixel as 8 zeros and ones... which should be stated "storing each pixel in 8 bits").
English grammar and spelling issues were corrected by a native editor. Nevertheless, we understand that the suggestion of Reviewer #1 in line 121-122 is more appropriate for a scientific paper. Done.
- Authors should clearly state that their method (in contrast to PIV) doesn't discern the velocity plane. E.g. Side view velocities can belong to different longitudinal sections.
This clarification has been included in the line 152-153.

Page 13. Figure 17. There appear to be 2 sets of "B" data, but the reason for this is not explained in the text or caption.
In the caption of Figure 17 and in line 333 a comment about that matter has been included.
Page 14. Figure 18 is not mentioned or discussed in the text.
The comment from line 341 to 343 is now included.
