However, when the hydraulic gradient acting on a test specimen is changed, the state of stress will also change, and, if the specimen or pore fluid is compressible, the volume of the test specimen or pore fluid will change.

Experience has sometimes shown that flow patterns in small, laboratory-prepared test specimens do not necessarily ast, the same patterns on large field scales and that hydraulic conductivities measured on small test specimens are not necessarily the same as larger-scale values.

The problem tends to be of minimal significance for materials that swell when exposed to water for example, compacted, clayey soils but can be a very serious problem d55856 materials that might tend to shrink and pull away from the walls of the permeameter.
