  2. Groundwater flow equation - Wikipedia

    en.wikipedia.org/wiki/Groundwater_flow_equation

    The transient flow of groundwater is described by a form of the diffusion equation, similar to that used in heat transfer to describe the flow of heat in a solid (heat conduction). The steady-state flow of groundwater is described by a form of the Laplace equation, which is a form of potential flow and has analogs in numerous fields.

  3. Groundwater flow - Wikipedia

    en.wikipedia.org/wiki/Groundwater_flow

    In hydrogeology, groundwater flow is defined as the "part of streamflow that has infiltrated the ground, entered the phreatic zone, and has been (or is at a particular time) discharged into a stream channel or springs; and seepage water." [1] It is governed by the groundwater flow equation. Groundwater is water that is found underground in ...

  4. Groundwater model - Wikipedia

    en.wikipedia.org/wiki/Groundwater_model

    The groundwater flow between neighboring prisms is calculated using 2-dimensional horizontal groundwater flow equations. Vertical flows are found by applying one-dimensional flow equations in a vertical sense, or they can be derived from the water balance: excess of horizontal inflow over horizontal outflow (or vice versa) is translated into ...

  5. Hydrological model - Wikipedia

    en.wikipedia.org/wiki/Hydrological_model

    Darcy's law describes steady, one-dimensional groundwater flow using the hydraulic conductivity and the hydraulic gradient: q → = − K ∇ h {\displaystyle {\vec {q}}=-K\nabla h} Groundwater flow equation describes time-varying, multidimensional groundwater flow using the aquifer transmissivity and storativity:

  6. Water table - Wikipedia

    en.wikipedia.org/wiki/Water_table

    In the aquifer, groundwater flows from points of higher pressure to points of lower pressure, and the direction of groundwater flow typically has both a horizontal and a vertical component. The slope of the water table is known as the “hydraulic gradient”, which depends on the rate at which water is added to and removed from the aquifer and ...

  7. Groundwater discharge - Wikipedia

    en.wikipedia.org/wiki/Groundwater_discharge

    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), dh/dl is the hydraulic gradient ([L·L −1]; unitless), and A is the area which the groundwater is flowing through ([L 2]; m 2) For example, this can be used to determine the flow rate of water flowing along a plane ...

  8. MODFLOW - Wikipedia

    en.wikipedia.org/wiki/MODFLOW

    MODFLOW simulation. MODFLOW is the U.S. Geological Survey modular finite-difference flow model, which is a computer code that solves the groundwater flow equation.The program is used by hydrogeologists to simulate the flow of groundwater through aquifers.

  9. Cone of depression - Wikipedia

    en.wikipedia.org/wiki/Cone_of_depression

    A cone of depression is a circular area surrounding a well where groundwater levels are reduced from pumping. [1] [2] In an unconfined aquifer (water table), this is an actual depression of the water levels. In confined aquifers , the cone of depression is a reduction in the pressure head surrounding the pumped well.
