This paper uses experiment model landforms to examine a complex fluvial system. Understanding sediment transport at stream junctions is non-trivial. Experimental model landforms are one way such systems can be examined as many variable can be controlled. As someone who has developed and used experimental model landscapes I can appreciate the work involved in creation and interpretation.
The Reviewers have done a thorough job and made many important suggestions. All agree that the paper is of interest and suitable for the journal. For me, the limitations section is very necessary. However, I have a query as to whether the paper needs some comment about the inclusion of some comment on how this issue could be examined in the field under field conditions?
In response the Authors have a done a very good job at addressing the comments.
I look forward to seeing the paper in print.
