WebIntroduction. The permeability of a soil is a measure of the ability of soil to allow water to pass through it. It is typically represented by the letter ‘k’ and is measured as the volume of water (m3) that can pass through an area (m2) per second (m3/ m2/s, or more simply m/s). WebPermeable surfaces (also known as porous or pervious surfaces) allow water to percolate into the soil to filter out pollutants and recharge the water table. Impermeable/impervious surfaces are solid surfaces that don’t …
