Permeability of different soils
A number of factors affect the permeability of soils, from particle size, impurities in the water, void ratio, the degree of saturation, and adsorbed water, to entrapped air and organic material. Websoil. Permeability of the different soil mixes was determined by the constant head test method and falling head test method. The direction of flow of water is also important, …
