31aquifer — /ak weuh feuhr/, n. any geological formation containing or conducting ground water, esp. one that supplies the water for wells, springs, etc. [1900 05; prob. < F aquifère (adj.); see AQUI , FER] * * * In hydrology, a rock layer or sequence that… …
32storage coefficient — 1. The volume of water an aquifer releases from or takes into storage per unit surface area of the aquifer per unit change in head [22]. In a confined aquifer, the water is derived from storage with decline in head resulting from an… …
33free — I (New American Roget s College Thesaurus) adj. at liberty, unrestrained; exempt; gratuitous, free of charge; lavish, profuse. v. t. unfetter, release; rid [of] (see ejection). See freedom, exemption, nonpayment, liberality. II (Roget s IV) modif …
34loose — I (New American Roget s College Thesaurus) adj. free, detached; flowing, unbound; vague, incoherent, diffuse; unrestrained, slack; dissipated, wanton, dissolute. See disjunction, impurity. v. t. free; loosen, unbind, undo; relax. See freedom. Ant …
35Aquifer test — An aquifer test (or a pumping test) is conducted to evaluate an aquifer by stimulating the aquifer through constant pumping, and observing the aquifer s response (drawdown) in observation wells. Aquifer testing is a common tool that… …
36Hydraulic conductivity — Hydraulic conductivity, symbolically represented as K, is a property of vascular plants, soil or rock, that describes the ease with which water can move through pore spaces or fractures. It depends on the intrinsic permeability of the material… …
37Specific storage — (Ss), storativity (S), specific yield (Sy) and specific capacity are material physical properties that characterize the capacity of an aquifer to release groundwater from storage in response to a decline in hydraulic head. For that reason they… …
38QCD matter — Quark matter or QCD matter (see QCD) refers to any of a number of theorized phases of matter whose degrees of freedom include quarks and gluons. These theoretical phases would occur at extremely high temperatures and densities, billions of times… …
39Geotechnical investigation — Geotechnical investigations are performed by geotechnical engineers or engineering geologists to obtain information on the physical properties of soil and rock around a site to design earthworks and foundations for proposed structures and for… …
40SahysMod — is a computer program for the prediction of the salinity of soil moisture, groundwater and drainage water, the depth of the water table, and the drain discharge in irrigated agricultural lands, using different hydrogeologic (aquifer) conditions,… …
