Based on publications in the field of soil physics new methods for the computation of the permeability and the hydraulic conductivity of porous media are derived. Up to five bundles of capillaries containing statistically distributed pore classes are succeeding each other, until pressure or tension equalization in a cross-section of the porous medium is assumed in the fluid upon flowing through the bundles of capillaries. Contrary to the method of computation in drying technology considering only one bundle of capillaries and supposing equalization of pressure or tension in the fluid in every cross section of the porous medium, the resistance factors or matching factors, respectively, have the same order of magnitude both in coarse-grained and fine-grained porous media. This fact is demonstrated for various soils. |
