Permeability of the soil
WebEarth and soil science [ edit] Permeability (earth sciences), a measure of the ability of a material (such as rocks) to transmit fluids. Relative permeability, in multiphase flow in porous media. Permeability (foundry sand), a test of the venting characteristics of a rammed foundry sand. Hydraulic conductivity, the permeability of soil for water. Websoil. Permeability of the different soil mixes was determined by the constant head test method and falling head test method. The direction of flow of water is also important, thus, vertical and both the horizontal orientations of permeameter were the used. A proposed set-up for the permeameter was used and modified to determine the horizontal
