Specific energy is the total head with respect to the channel bottom. It is a summation of the velocity head and the depth of flow at a given cross-section. Specific energy has proven to be very useful in the analysis of open-channel flow.
For rectangular channel
E= 1.5yc or (3/2)yc
or
yc = (2/3)E
Where E= Specific energy , yC = Critical depth
For triangular section
E= 1.25yc
