“X” – upstream point “Y” – downstream

“X” – critical energy point “Y” – outwards

“X” – point of change “Y” – outwards

“X” – downstream point “Y” – upstream

The total energy related to the flow at that point of change

Minimum depth hydrostatic flow energy and velocity flow energy

The minimum specific energy of the flow

Elevation head, hydrostatic head and velocity head

hydrostatic head and velocity head

Elevation head and velocity head

Velocity head only

Always the normal energy

Always the critical energy of the flow

The larger energy value when an energy analysis is performed between two points in the channel flow
