flow. At a larger depth the same discharge may be delivered through the section with a smaller velocity and a higher specific energy than a critical depth. It is known as subcritical flow. For a given value of specific energy, E1, the discharge may pass through the channel section at either depth d1 (supercritical flow) or d2 (subcritical flow).

The total energy of a channel flow referred to datum is given by, g V H z y 2 2 = + + () If the datum coincides with the channel bed at the cross-section, the resulting expression is know as specific energy and is denoted by E.

Thus, specific energy is the energy at a cross-section of an open channel flow with respect to the channel bed. OPEN CHANNEL FLOW: uniform motion M.
