Universal Permeability test

The permeability test is conducted on soils to determine the rate at which the soil allows water to flow through it. Soil permeability depends on the grain structure of the soil and the void spaces in the soil.There are several laboratory and in situ tests that can be done to estimate the permeability of the soil and every test has its own advantages and disadvantages. The two most common are “the constant head permeability method” and “the falling head permeability method”.
