WebJun 26, 2024 · Soil permeability is the quality of a soil enabling it to transmit air or water through the soil pores. Texture, structure, cracking, and the amount of organic matter influence the permeability. The permeability of the least permeable horizon should be … If a soil is moister, it requires less rainfall to reach the point where the soil becomes … The coefficient of permeability varies with the void ratio as e/sup>/(1+e). For a given soil, the greater the void ratio, the higher the value of the coefficient of permeability. Here 'e' is the void ratio. Based on other concepts it has been established that the permeability of a soil varies as e or e /(1+e). Whatever may be the exact relationship, all soils have e versus log k plot as a straight line.
