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. http://www.civil.uwaterloo.ca/maknight/courses/CIVE353/Lectures/week%203/permeability.pdf nash rambler wheels
