Terminology Head

Water must fall from a higher elevation to a lower one to release its stored energy.

The difference between these elevations is called head

Dams: three categories high-head (800 or more feet) medium-head (100 to 800 feet) low-head (less than 100 feet)

Power is proportional to the product of head x flow
