Hydraulic head is a measure of the amount of energy groundwater, flowing through an aquifer, has per unit weight. The word head indicates that the quantity is expressed in terms of a length of water (1.0 m of head is equivalent to 9.8 kPa or 1 ft of head is equal to 0.43 psi or 3.0 kPa of pressure.) In hydrogeology, it is convention to use gauge pressure (pressure measured greater than atmospheric pressure), when speaking of pressure head (unless absolute pressure is explicitly specified).
