Experimental and numerical modelling of symmetrical four-branch supercritical cross junction flow

Abstract

The discussers congratulate the authors for their work and would like to raise some questions and comments about their results ans statements. The papers compares the computed with the measured flow depths for five flow configurations and the computed with the measured discharges for more than 200 configurations. The authors found discrepancies concerning the prediction of the location and the thickness of the oblique jumps mainly because these are set on one cell in the numerical model.
