  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 .

    Piezoelectric balance presented by Pierre Curie to Lord Kelvin, Hunterian Museum, Glasgow. Piezoelectricity (/ ˌ p iː z oʊ-, ˌ p iː t s oʊ-, p aɪ ˌ iː z oʊ-/, US: / p i ˌ eɪ z oʊ-, p i ˌ eɪ t s oʊ-/) [1] is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins—in ...

  4. 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.

    Part 1 of the manual approaches the process of research and writing. This includes providing "practical advice" to formulate "the right questions, read critically, and build arguments" as well as helping authors draft and revise a paper. [3] Initially added with the seventh edition of the manual, this part is adapted from The Craft of Research ...

  6. 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.

  7. Specific storage - Wikipedia

    en.wikipedia.org/wiki/Specific_storage

    For a confined aquifer or aquitard, storativity is the vertically integrated specific storage value. Specific storage is the volume of water released from one unit volume of the aquifer under one unit decline in head.
