WebWhat soil has high porosity? The most porous is clay. Clay acts as an aquitard, blocking the flow of water. Gravel and sand are porous, which makes them good candidates for underground sources of water. Porosity is a measure of the resistance of a material to flow. The more porous the material, the easier it is for water to move through it.
