Conversion Basis
Hydraulic conductivity, often denoted k, is commonly reported in m/s, cm/s, ft/day, or similar length-per-time units. The converted value represents the same conductivity magnitude; it does not account for fluid viscosity or test conditions.
target k = source k x source-to-meter-per-second factor / target factor
Common Examples
- 1 m/day = 1.15741 x 10^-5 m/s
- 1 x 10^-6 m/s = 1 x 10^-4 cm/s
- 1 ft/day = 3.52778 x 10^-6 m/s
Engineering Use and Limitations
- Hydraulic conductivity depends on soil fabric, density, saturation, stress state, temperature, and permeant properties.
- Intrinsic permeability has dimensions of area and is not the same quantity as hydraulic conductivity.
- When comparing laboratory and field values, consider scale effects, anisotropy, sample disturbance, and test method.
