Aquifer test (or a pumping test) is a field experiment in which a well is pumped at a controlled rate and the aquifer's response (drawdown) is measured in one or more observation wells. [ 5 ] Cone of depression is a conically-shaped depression that is produced in a water table as a result of pumping water from a well at a given rate.
where s is the drawdown (change in hydraulic head at a point since the beginning of the test in units of distance), u is a dimensionless parameter, Q is the discharge (pumping) rate of the well (volume per unit time), T and S are the transmissivity and storativity of the aquifer around the well (distance squared per unit time and dimensionless ...
In hydrology, a well test is conducted to evaluate the amount of water that can be pumped from a particular water well.More specifically, a well test will allow prediction of the maximum rate at which water can be pumped from a well, and the distance that the water level in the well will fall for a given pumping rate and duration of pumping.
SPR – slow pumping rate; SPROF – seismic profile; SPS – subsea production systems; SPT – shallower pool test, Lahee classification [citation needed] SPUD – spud date (started drilling well) SPWLA – Society of Petrophysicists and Well Log Analysts [29] SQL – seismic quicklook log; SQZ – squeeze job; SR – shear rate
The rates of decline slowed in the 1970s and '80s as newly built aqueducts brought river water to farmlands, and the sinking remained less pronounced into the early 2000s.
Because the flow rate into or out of the well is not constant, as is the case in a typical aquifer test, the standard Theis solution does not work. Mathematically , the Theis equation is the solution of the groundwater flow equation for a step increase in discharge rate at the pumping well; a slug test is instead an instantaneous pulse at the ...
