  2. Potentiometric surface - Wikipedia

    en.wikipedia.org/wiki/Potentiometric_surface

    For groundwater "potentiometric surface" is a synonym of "piezometric surface" which is an imaginary surface that defines the level to which water in a confined aquifer would rise were it completely pierced with wells. [1] If the potentiometric surface lies above the ground surface, a flowing artesian well results.

  3. Aquifer properties - Wikipedia

    en.wikipedia.org/wiki/Aquifer_properties

    The aquifer properties of the aquifer essentially depend upon the composition of the aquifer.The most important properties of the aquifer are porosity and specific yield which in turn give its capacity to release the water in the pores and its ability to transmit the flow with ease.

  4. Electroanalytical methods - Wikipedia

    en.wikipedia.org/wiki/Electroanalytical_methods

    In fact, since the potentiometric measurement is a non-destructive measurement, assuming that the electrode is in equilibrium with the solution, we are measuring the solution's potential. Potentiometry usually uses indicator electrodes made selectively sensitive to the ion of interest, such as fluoride in fluoride selective electrodes , so that ...

  5. Groundwater model - Wikipedia

    en.wikipedia.org/wiki/Groundwater_model

    Typical aquifer cross-section. An unambiguous definition of "groundwater model" is difficult to give, but there are many common characteristics. A groundwater model may be a scale model or an electric model of a groundwater situation or aquifer. Groundwater models are used to represent the natural groundwater flow in the environment.

  6. Oklahoma Water Resources Board - Wikipedia

    en.wikipedia.org/wiki/Oklahoma_Water_Resources_Board

    In Oklahoma, streamwater is defined to include “water in ponds, lakes, reservoirs, and playa lakes” [2] (or dry lakes). Streamwater is considered to be publicly owned; the Oklahoma Water Resources board is responsible for appropriation for all areas of the State of Oklahoma except the Grand River basin, where the Grand River Dam Authority (GRDA) has responsibility for allocation on a use ...

  7. Groundwater discharge - Wikipedia

    en.wikipedia.org/wiki/Groundwater_discharge

    Groundwater discharge is the volumetric flow rate of groundwater through an aquifer. Total groundwater discharge, as reported through a specified area, is similarly expressed as: = where Q is the total groundwater discharge ([L 3 ·T −1]; m 3 /s), K is the hydraulic conductivity of the aquifer ([L·T −1]; m/s),

  8. Analysis of water chemistry - Wikipedia

    en.wikipedia.org/wiki/Analysis_of_water_chemistry

    Water chemistry analysis is often the groundwork of studies of water quality, pollution, hydrology and geothermal waters. Analytical methods routinely used can detect and measure all the natural elements and their inorganic compounds and a very wide range of organic chemical species using methods such as gas chromatography and mass spectrometry .

  9. Potentiometric titration - Wikipedia

    en.wikipedia.org/wiki/Potentiometric_titration

    In analytical chemistry, potentiometric titration is a technique similar to direct titration of a redox reaction. It is a useful means of characterizing an acid . No indicator is used; instead the electric potential is measured across the analyte , typically an electrolyte solution.
