thickness of aquifer
1Aquifer — 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… …
2Aquifer 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… …

8Guaraní Aquifer — The Guaraní Aquifer, located beneath the surface of the original four Mercosur countries (Argentina, Brazil, Paraguay and Uruguay), is one of the world s largest aquifer systems and an important source of fresh water for its people. [… …
9Specific 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… …
10Groundwater flow equation — Used in hydrogeology, the groundwater flow equation is the mathematical relationship which is used to describe the flow of groundwater through an aquifer. The transient flow of groundwater is described by a form of the diffusion equation, similar …
