Interactive comment on “A bed load transport equation based on the spatial distribution of shear stress – Oak Creek revisit” by Angel Monsalve et al

and previous transport equations that the authors could emphasize more strongly. This would raise the discussion from a more technical level about how the data were collected and analyzed to include new scientific knowledge that the author’s results lead to. For example, it is perhaps not widely recognized that existing transport equations more or less require the that the entire shear stress distribution in a reach be scaled by a single parameter, the mean that is estimated by the reach averaged depth-slope product. While this assumption may be true in certain cases, for example in straight reaches with few large roughness elements, it is unlikely to be true for complex reaches with variable planforms and roughness characteristics.
