  2. Drawdown (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Drawdown_(hydrology)

    In subsurface hydrogeology, drawdown is the reduction in hydraulic head observed at a well in an aquifer, typically due to pumping a well as part of an aquifer test or well test. In surface water hydrology and civil engineering , drawdown refers to the lowering of the surface elevation of a body of water, the water table, the piezometric ...

  3. Aquifer test - Wikipedia

    en.wikipedia.org/wiki/Aquifer_test

    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 ...

  4. Well test - Wikipedia

    en.wikipedia.org/wiki/Well_test

    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.

  5. Hydraulic tomography - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_tomography

    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 into several intervals along the depth using pac

    A drawdown of the Upper Delaware River reservoirs is set to start June 1. This will help mitigate flood risk while the Delaware Aqueduct is repaired.

  7. Water testing - Wikipedia

    en.wikipedia.org/wiki/Water_testing

    Water testing being conducted at a treatment facility in Broken Bow, Oklahoma. Water testing is a broad description for various procedures used to analyze water quality. Millions of water quality tests are carried out daily to fulfill regulatory requirements and to maintain safety. [1] Testing may be performed to evaluate:

  8. Drill stem test - Wikipedia

    en.wikipedia.org/wiki/Drill_stem_test

    A drill stem test (DST) is a procedure for isolating and testing the pressure, permeability and productive capacity of a geological formation during the drilling of a well. The test is an important measurement of pressure behaviour at the drill stem and is a valuable way of obtaining information on the formation fluid and establishing whether a ...
