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 ((); m3/s),
:''K'' is the hydraulic conductivity of the aquifer ((); m/s),
:''dh/dl'' is the hydraulic gradient ((); unitless), and
:''A'' is the area which the groundwater is flowing through ((); m2)
For example, this can be used to determine the flow rate of water flowing along a plane with known geometry.
