CT: Aquifer tests (pumping tests, slug tests and constant-head tests) are performed to estimate the hydraulic properties of aquifers and aquitards including horizontal and vertical hydraulic conductivity, storativity, specific yield and porosity.

N: 1. – hydraulic (adj): “pertaining to fluids in motion,” c. 1600, from French hydraulique, from Latin hydraulicus, from Greek hydraulikos (organon) “water organ,” the name of a musical instrument invented by the Egyptian Ctesibius, from hydr-, stem of hydor “water” (from suffixed form of PIE root *wed- (1) “water; wet”) + aulos “musical instrument, hollow tube, pipe”. Extended by the Romans to other water engines.
– conductivity (n): From adjective conductive (1520s, “having the power or property of leading” (a sense now obsolete), from conduct (v.) + -ive. Physics sense, “resulting from or pertaining to conduction,” is from 1840. Related: Conductivity, from 1837) and -ity (word-forming element making abstract nouns from adjectives and meaning “condition or quality of being,” from Middle English -ite, from Old French -ete (Modern French -ité) and directly from Latin -itatem (nominative -itas), suffix denoting state or condition, composed of -i- (from the stem or else a connective) + the common abstract suffix -tas; roughly, the word in -ity usually means the quality of being what the adjective describes, or concretely an instance of the quality, or collectively all the instances; & the word in -ism means the disposition, or collectively all those who feel it. Fowler).
2. The hydraulic conductivity of a soil is a measure of the soil’s ability to transmit water when submitted to a hydraulic gradient. Hydraulic conductivity is defined by Darcy’s law, which, for one-dimensional vertical flow.
3. The proportionality factor in Darcy’s law as applied to the viscous flow of water in soil, that is, the flux of water per unit gradient of the hydraulic potential.
4. The proportionality coefficient, K, of Darcy’s law, commonly referred to as the hydraulic conductivity, expresses the interaction between the fluid and the media.
