"WebAs the angularity of the grains rises, the porosity of the sediment decreases because the granules can pack closer together, with the bumps of some grains fitting into indentations in others. Because small grains can occupy the crevices between larger grains, the porosity of the particles is reduced if it is inadequately sorted. " - Porosity in granular filtration
