WebFigure 5.1 Groundwater flow in the vicinity of (a) an impermeable boundary, (b) a constant-head boundary, and (c) a water-table boundary. In effect, any flowline in a flow net constitutes an imaginary impermeable boundary, in that there is no flow across a flowline.

WebThe groundwater flow gradient and direction calculator allows the user to enter measured well (piezometer) levels in up to 10 groundwater observation wells. The … Webq = −K = −K Hydraulic gradient ∆l dl K is hydraulic conductivity and has units of velocity (L/T). It is a function of both media and fluid. Q is a flow per unit cross section and is not the actual velocity of groundwater flow. ∆h represents the frictional energy loss due to flow through media. Darcy’s law is a macroscopic law.
Webwhere Q is the volume of the groundwater flow (m 3 /s), K is the hydraulic conductivity (m/s), i is the hydraulic gradient, and A is the cross-sectional area of the aquifer. The following equation can be used to determine the flux (i.e., volume per unit time) of groundwater passing through the area of the aquifer being considered.
