  2. Hydraulic head - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_head

    Hydraulic head or piezometric head is a measurement related to liquid pressure (normalized by specific weight) and the liquid elevation above a vertical datum. [ 1 ] [ 2 ] It is usually measured as an equivalent liquid surface elevation, expressed in units of length, at the entrance (or bottom) of a piezometer .

  3. Potentiometric surface - Wikipedia

    en.wikipedia.org/wiki/Potentiometric_surface

    For groundwater "potentiometric surface" is a synonym of "piezometric surface" which is an imaginary surface that defines the level to which water in a confined aquifer would rise were it completely pierced with wells. [1] If the potentiometric surface lies above the ground surface, a flowing artesian well results.

  4. Piezoelectric sensor - Wikipedia

    en.wikipedia.org/wiki/Piezoelectric_sensor

    A force applied along a neutral axis (y) displaces charges along the (x) direction, perpendicular to the line of force. The amount of charge depends on the geometrical dimensions of the respective piezoelectric element. When dimensions ,, apply, = /,

  5. Drawdown (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Drawdown_(hydrology)

    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]

  8. Pore water pressure - Wikipedia

    en.wikipedia.org/wiki/Pore_water_pressure

    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.
