Darcy law of groundwater flow
WebDarcy's Law states that the Darcy velocity q in a porous medium is calculated from the hydraulic conductivity K and the head gradient (the change in head per unit length in the direction of flow in an isotropic … WebCombining these proportionalities leads to Darcy’s Law, the empirical law that describes groundwater flow: Q = KA(h 1 – h 2)/ΔL) Q = KA(Δh/ΔL) The above equation can also be recast in terms of the water volume flux per unit area, Q/A (also called "Darcy flux" or "Darcy velocity" with units of length per time): Q/A = q = K(Δh/ΔL) where ...

WebA mass balance must be performed, and used along with Darcy's law, to arrive at the transient groundwater flow equation. This balance is analogous to the energy balance used in heat transfer to arrive at the heat equation. It is simply a statement of accounting, that for a given control volume, aside from sources or sinks, mass cannot be ...
