Comment on “Estimation of composite hydraulic resistance in ice‐covered alluvial streams” by Ghareh Aghaji Zare et al.

Abstract

Inconsistencies between basic hydraulics and hypotheses advanced by the authors are identified. They are attributed primarily to weaknesses in the analysis of velocity measurements in the ice‐controlled flow layer and suggestions for improvement are offered.

Reply to comment by Spyros Beltaos on “Estimation of composite hydraulic resistance in ice‐covered alluvial streams”

“…Other approaches and assumptions regarding the calculation of hydraulic radii are discussed in the paper. Note that the discussant suggested the authors misinterpreted that Larsen [1969] and Beltaos et al [2012] assumed R i 5 R b in general [Beltaos, 2016]. In fact, the authors wrote that Larsen [1969] and Beltaos et al [2012] assumed that R c 5 Y t /2 (in which Y t is the total depth) not R i 5 R b .…”
