Permeability of clay soil
WebPERMEABILITY TEST METHOD A. SCOPE. The permeability test is a measure of the rate of the flow of water through soil. In this test, water is forced by a known constant pressure through a soil specimen of known dimensions and the rate of flow is determined. This test is used primarily to. determine the suitability of sands and gravels WebApr 16, 2024 · Clay soils are known to have low permeability, which results in low infiltration rates and poor drainage. As more water fills the pore space, the air is pushed out. When all pore spaces in the soil are filled with water, the soil becomes saturated. Why is the permeability of clay low?
