Aquifer — Typical aquifer cross section An aquifer is a wet underground layer of water bearing permeable rock or unconsolidated materials (gravel, sand, or silt) from which groundwater can be usefully extracted using a water well. The study of water flow… … Wikipedia
storage 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 . In a confined aquifer, the water is derived from storage with decline in head resulting from an… … Lexicon of Cave and Karst Terminology
Aquifer 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… … Wikipedia

Compressed air energy storage — Conceptual representation of the compressed air energy storage concept. Off peak (low cost) electrical power compresses air into an underground air storage “vessel” (the Norton mine), and later the air feeds a gas fired turbine generator complex… … Wikipedia
Compressed-air energy storage — (CAES) refers to the compression of airto be used later as energy source. At utility scale, it can be stored during periods of low energy demand (off peak), for use in meeting periods of higher demand (peak load). Alternatively it can be used to… … Wikipedia
Specific 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… … Wikipedia
