  2. Hydraulic conductivity - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_conductivity

    Saturated hydraulic conductivity, K sat, describes water movement through saturated media. By definition, hydraulic conductivity is the ratio of volume flux to hydraulic gradient yielding a quantitative measure of a saturated soil's ability to transmit water when subjected to a hydraulic gradient.

  3. Groundwater flow equation - Wikipedia

    en.wikipedia.org/wiki/Groundwater_flow_equation

    Assuming both the hydraulic conductivity and the horizontal components of flow are uniform along the entire saturated thickness of the aquifer (i.e., / = and / =), we can express Darcy's law in terms of integrated groundwater discharges, Q x and Q y:

  4. Pore space in soil - Wikipedia

    en.wikipedia.org/wiki/Pore_space_in_soil

    Hydraulic conductivity (K) is a property of soil that describes the ease with which water can move through pore spaces. It depends on the permeability of the material (pores, compaction) and on the degree of saturation. Saturated hydraulic conductivity, K sat, describes water movement through saturated media. Where hydraulic conductivity has ...

  5. Richards equation - Wikipedia

    en.wikipedia.org/wiki/Richards_equation

    Further the saturated hydraulic conductivity (which is for non isotropic environment a tensor of second order) should also be provided. Identification of these parameters is often non-trivial and was a subject of numerous publications over several decades.

  6. Darcy's law - Wikipedia

    en.wikipedia.org/wiki/Darcy's_law

    where q is the volume flux vector of the fluid at a particular point in the medium, h is the total hydraulic head, and K is the hydraulic conductivity tensor, at that point. The hydraulic conductivity can often be approximated as a scalar. (Note the analogy to Ohm's law in electrostatics. The flux vector is analogous to the current density ...

  7. Disc permeameter - Wikipedia

    en.wikipedia.org/wiki/Disc_permeameter

    The disc permeameter is a field instrument used for measuring water infiltration in the soil, which is characterized by in situ saturated and unsaturated soil hydraulic properties. It is mainly used to provide estimates of the hydraulic conductivity of the soil near saturation.

  8. Infiltration (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Infiltration_(hydrology)

    is the hydraulic conductivity; is the vague total depth of subsurface ground in question. This vague definition explains why this method should be avoided. or = [+ +] [17] Infiltration rate f (mm hour −1))

  9. Soil consolidation - Wikipedia

    en.wikipedia.org/wiki/Soil_consolidation

    This is especially true in saturated clays because their hydraulic conductivity is extremely low, and this causes the water to take an exceptionally long time to drain out of the soil. While drainage is occurring, the pore water pressure is greater than normal because it is carrying part of the applied stress (as opposed to the soil particles).
