The pressure in a fluid at a given point expressed in terms of the vertical height of the liquid column above that point which would produce the same pressure.
The pressure equivalent to that exerted on a surface by a column of water of a given height.
The pressure developed by a liquid within a liquid-saturated, porous, or crevassed rock. the hydrostatic pressure of the liquid in a saturated porous rock, as measured at the bottom of a borehole, generally is approximately equal to the hydraulic head developed by a vertical column of water as high as the depth of the borehole meas¬ured downward from the water table. see hy¬draulic head 2.
