WitrynaThis is particularly important for soft materials, since their permeability could vary within several orders of magnitude depending on the variation of void ratio. The article … WitrynaIn the laboratory, two common tests are generally used to determine this soil property. These two tests are the falling head permeability test and the constant head permeability test. Which test is used depends upon the type of soil to be tested. For soils of high permeability (sands and gravels) a constant head test is used.
