Darcy's law is an equation that describes the flow of a fluid through a porous medium. The law was formulated by Henry Darcy based on results of experiments on the flow of water through beds of sand, forming the basis of hydrogeology, a branch of earth sciences
Define Darcy's law. Darcy's law synonyms, Darcy's law pronunciation, Darcy's law translation, English dictionary definition of Darcy's law. n. Geology A law stating that the rate at which a fluid flows through a permeable medium, such as an aquifer, is directly proportional to the drop in...
Darcy's law is essentially similar to Fick's law for diffusion, which describes the flux (J) of a diffuse species as a function of a proportionality constant, the diffusivity (D), and the gradient in concentration of the species ([nabla]C):
Previous studies using Soil Water Assessment Tool (SWAT) did not simulate well stream flow during storm events. A dimensionless theoretical model based on Darcy's law developed by University of Washington in St Louis was applied and significantly improved the hydrograph simulation.
The law that the rate at which a fluid flows through a permeable substance per unit area is equal to the permeability, which is a property only of the substance through which the fluid is flowing, times the pressure drop per unit length of flow, divided by the viscosity of the fluid.
Commercial compositional simulators commonly apply correlations or empirical relations based on tuned experimental data to calculate phase relative permeabilities. These relations cannot adequately capture effects of hysteresis, fluid compositional
This research is being conducted in the Piedmont region of the Southeastern US, specifically in Surry County, NC. We are using a comparative study approach with three stream reaches all agricultural lands with a mix of row crop and pasture: (1) a stream restored in 2012, (2) a channelized ditch with little riparian vegetation and (3) an impacted stream with a forested riparian buffer.
