WebJul 23, 2011 · Note that calculation of the critical slope is the same for a rectangular channel or a trapezoidal channel, after the critical depth has been determined. The Manning equation is a dimensional equation, in which the following units must be used: Q is in cfs, A c is in ft 2 , R hc is in ft, and S c and n are dimensionless. Weblook at every possible instance of critical depth problems. What is critical depth? In open channel hydraulics, critical depth is the depth of flow (for a given discharge) where the specific energy is at a minimum. The total energy head (specific energy) for a cross section is given by: g αV H WS 2 2 = +

WebApr 5, 2024 · Explanation: For a given value of specific energy, the critical depth gives the greatest discharge in an open channel, or conversely, for a given discharge, the specific energy is a minimum for the critical depth. So at a control section, the discharge can be calculated once the depth is known e.g.
