Critical depth in rectangular channel
WebMar 1, 2011 · The critical and normal depths play a major role in the design, operation, and maintenance of open channels [1]. The critical depth is a quantity of fundamental … WebThe critical depth for a rectangular channel can be calculated from the fact that the Froude number is equal to one at critical flow conditions. For a rectangular channel , this fact leads to the equation: Vc/ (gyc)1/2 = 1, where the subscript c is used to indicate critical flow conditions for the velocity and depth.
