Determination of coefficient of permeability from soil percolation test. In Proceedings of the 12th lnternational Conference of lACl\/lACr (pp. 1824-1881). WebIt was studied by Allen Hazen that the coefficient of permeability (k) of a soil is directly proportional to the square of the particle size (D). Thus permeability of coarse grained soil is very large as compared to that of fine grained soil. The permeability of coarse sand may be more than one million times as much that of clay. WebThe falling head permeability test is a common laboratory testing method used to determine the permeability of fine grained soils with intermediate and low permeability such as silts and clays.
