1 Hydraulic conductivity, a property of a porous material's ability to transmit water. 2  Thermal conductivity, the intensive property of a material that indicates its ability to conduct heat.  Rayleigh conductivity, describing the behavior of apertures concerning the flow of a liquid or gas.
Conductivity is a measure of waterâs capability to pass electrical flow. This ability is directly related to the concentration of ions in the water 1. These conductive ions come from dissolved salts and inorganic materials such as alkalis, chlorides, sulfides and carbonate compounds 3.
