http://www.aqtesolv.com/aquifer-tests/aquifer_properties.htm In science and engineering, hydraulic conductivity (K, in SI units of meters per second), is a property of porous materials, soils and rocks, that describes the ease with which a fluid (usually water) can move through the pore space, or fractures network. It depends on the intrinsic permeability (k, unit: m ) of the material, the degree of saturation, and on the density and viscosity of the fluid. Saturated hydraulic conductivity, Ksat, describes water movement through saturated media. By definition, …
WebA hydraulic conductivity curve tells you, at a given water potential, the ability of the soil to conduct water. One factor that affects hydraulic conductivity is how strong the structure is in the soil you’re measuring. For example, as the soil dries, what is the ability of water to go from the top of a sample [or soil layer in the field] to ... WebOct 30, 2006 · Price et al. (1993) noted the importance of the saturated hydraulic conductivity, K s, of the Chalk matrix, which will vary from site to site. Where the matrix K s is high, for example, at the sites looked at by Wellings (1984) , high infiltration rates can be accommodated by the Chalk matrix, and conversely where it is low, fracture flow will ...
