WebCritical depth occurs when the flow in a channel has a minimum specific energy.Specific energy refers to the sum of the depth of flow and the velocity head. Critical depth depends on the channel shape and flow rate. The depth of flow at the culvert outlet is assumed to be equal to critical depth for culverts operating under outlet control with low tailwater. Weba given discharge in regular channel cross sections. The depth at which the specific energy is minimum is called the critical depth. At the critical depth, the Froude number has a value of 1.0 at that specific location within a reach. The critical depth is also the depth of maximum discharge when the specific energy is held constant.
