FORMULA FOR CALCULATING CRITICAL DEPTH OF TRAPEZOIDAL OPEN CHANNEL. DISCUSSIONS

Two discussions of a technical note with the aforementioned title by Z. Wang, published in this journal (Volume 124, Number 1, January 1998), are presented. The first discusser questions the accuracy of the explicit formula derived by the author to calculate the critical depth of trapezoidal open channel flow and points out that the equation should involve the momentum correction coefficient, not the energy correction coefficient. The remaining two discussers offer a simpler explicit solution to the same problem.
