A head of water is superimposed on the undisturbed water-saturated soil sample. The water will flow through with a certain speed per unit time.
Soil water permeability is the property of the soil pore system allowing fluid to flow through. Generally the pore sizes and their connectivity determine whether a soil has high or low permeability. Water will flow easily through soil with large pores with good connectivity between them. Small pores with the same degree of connectivity would have lower permeability, because water would flow through the soil more slowly.
In many land use systems worldwide soil deformation is a major problem due to increasing land use intensity. Altered soil functions, in particular reduced hydraulic conductivities and impeded aeration, may decrease crop growth and productivity as well as the filtering and buffering capacity of soils. A commonly applied method for the influence of compaction on permeability is determining the hydrologic permeability before and after static loading in oedometer tests.
