In the manuscript ”Entrainment and deposition of boulders in a gravel bed river”, the authors present a simple method using drone photos to evaluate bedload transport of boulders over several years. They relate the presence/absence of boulders to measured discharge to determine which flows are necessary to transport boulders of various sizes.
Although I find the technique to be interesting and simple and could thus provide simple measurements of bedload transport and flux, I also find the calculations to be filled with abundant assumptions, of which only a few are addressed, and no uncertainty calculations are presented.
I also had a very hard time understanding the GIS methods. I think there was some kind of language issue in what is meant by ’GIS’. I couldn’t figure out if the authors meant ’orthophotos’ or a specific analysis when referring to ’GIS’. ’GIS’ usually refers to the concept of geographic information systems or a software. Here they seem to use it as in referring to a specific data type of a map, perhaps? Furthermore, some kind of estimate of error in the size determination of boulders from the drone photos would be useful. How accurately could the boulders be digitized and thus quantified?
