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
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
Slug test — A slug test is a particular type of aquifer test where water is quickly added or removed from a groundwater well, and the change in hydraulic head is monitored through time, to determine the near well aquifer characteristics. It is a method used… … Wikipedia
Well test — This article discusses water well testing; the testing of other wells, eg. petroleum wells, is a separate field.A well test is conducted to evaluate the amount of water that can be pumped from a particular water well. More specifically, a well… … Wikipedia
pumping test — A test designed to determine aquifer characteristics by pumping a well and plotting the drawdown curves of observation wells for comparison with theoretical curves … Lexicon of Cave and Karst Terminology
Hydrogeology — ( hydro meaning water, and geology meaning the study of the Earth) is the area of geology that deals with the distribution and movement of groundwater in the soil and rocks of the Earth s crust, (commonly in aquifers). The term geohydrology is… … 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
Hydraulic 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… … Wikipedia
Hydraulic tomography — (HT) is a sequential cross hole hydraulic test followed by inversion of all the data to map the spatial distribution of aquifer hydraulic properties. Specifically, HT involves installation of multiple wells in an aquifer, which are partitioned… … Wikipedia
Hydrograph — There are two meanings for hydrographs both coming from hydro meaning water, and graph meaning chart. A hydrograph plots the discharge of a river as a function of time. This activity can be in response to episodal event such as a… … Wikipedia
