Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum. [ 1 ] [ 2 ] It is usually measured as a liquid surface elevation, expressed in units of length, at the entrance (or bottom) of a piezometer .
Hydraulic head (or piezometric head) is a specific measurement of the potential of water above a vertical datum. [7] It is the height of the free surface of water above a given point beneath the surface. [4] Pumping level is the level of water in the well during pumping. [8] Specific capacity is the well yield per unit of drawdown. [8]
This can slower and concentrate the fluid migration. The fault zone facilitates vertical downwards movement of CO 2 due to its buoyancy and piezometric head differences, i.e. pressure/ hydraulic head is greater at a higher elevation, which helps store CO 2 at depth. [6] Gif 4. This gif shows how fluid (CO 2) is facilitated by a fault zone.
The standard method for measuring pore water pressure below the water table employs a piezometer, which measures the height to which a column of the liquid rises against gravity; i.e., the static pressure (or piezometric head) of groundwater at a specific depth. [6] Piezometers often employ electronic pressure transducers to provide data.

Pressure head is a component of hydraulic head, in which it is combined with elevation head. When considering dynamic (flowing) systems, there is a third term needed: velocity head. Thus, the three terms of velocity head, elevation head, and pressure head appear in the head equation derived from the Bernoulli equation for incompressible fluids:
The head can only be found by calculation or defined by observations with and without impoundment. Depending on the flow rate and control of the barrage, locks or weir, position will greatly vary and will not necessarily be where the so-called headworks are.
